The Satyanarayan Puja is a Hindu (Devanāgarī: हिन्दु) religious observance. It is a ritual performed by Hindus before/on any major occasion. The Satyanarayana Puja is usually done on the Purnima day of every month (the day of the full moon) or a Sankranti. It is also done on special occasions and during times of achievements as an offering of gratitude to the Lord.

The puja starts by a prayer to Lord Ganesha, to remove all obstacles that may occur as a result of incorrectly performing the puja. This is done by chanting all the names of Lord Ganesha and offering prasad (a food offering, usually consisting of one of Lord Ganesha's favorite foods - modak, a sugar and coconut mixture, or lhadu) and the showering of flower petals.

Another part of the prayer involves a prayer to the Navagraha's - the nine important celestial beings in the universe. They consist of Surya (the Sun), Chandra (the moon), Angaaraka/Chevaai (Mars), Budha (Mercury), Guru aka Bruhaspati (Jupiter), Shukra (Venus), Sani (Saturn), Rahu (the head of the Demon snake), and Ketu (the tail of the Demon snake).

The rest of the puja consists of worship to Satyanarayana, an extremely benevolent form of Lord Vishnu. First "panchamritam" is used to clean the place where the deity is placed. After placing the deity in the correct position, Satyanaraya swami is worshipped. Names of Satyanarayana are chanted along with offering of a variety of prasad (including a mixture of milk, honey, ghee/butter, yogurt, sugar) and flower petals.

Another requirement of the puja is that the story of the puja be heard among all those observing and partaking in the pooja. The story involves the origin of the puja, the benefits of it, and the potential mishaps that may occur with the careless performance of the puja.

The prayer concludes with an Aarti, which consists of revolving a small fire-lit-lamp in the vicinity of an image of the Lord. After the puja is over, participants and observers of the pooja are required to ingest in the prasad that was offered and blessed by the Lord.

It is told that Satyanarayan Katha is in REVA volume of Skanda Purana. But this volume is devoted to pilgrimages on the valley of river REVA. In Satyanarayana there is no Reva river. In original Skanda Purana there is nothing like Satyanarayana. Recent Skanda Puranas added it with clear note of its new addition in Skanda.

The paper to be presented by TCR Engineering Services (www.tcreng.com) will be on the following topic:

METALLURGICAL QUALITY CONTROL FOR HEAT TREATMENT INDUSTRIES

Paresh Haribhakti and V K Bafna

Abstract:

Varieties of heat treatment are done on metallic engineering components to achieve desired mechanical properties and enhanced service life. Improved designs and engineering practices, rising production cost which has compelled industries to opt for high production volumes at a lower cost has propelled the heat treatment industries to reduce rejection and achieve perfection. In this present context a well organized modern in house quality control is a must for any heat treatment shop. Conventional practice of Hardness Test in vogue is often misleading as it does not reflect all the metallurgical parameters that the new design aspects demand more and more. Microstructure Examination, Magnetic Particle, ultrasonic and Dye Penetrant Testing, Mechanical Testing, micro hardness testing are gaining ground besides Dimensions and Hardness Measurements.

Microstructure can draw inferences with regard to metal cleanliness, prior austenite grain size, soaking time, effectiveness of hardening and tempering, solution annealing, precipitation hardening, etc. With radical changes in demands from the design with regard to surface engineering aspects, surface treatment like carburizing, nitriding, induction hardening and others require micro structural interpretation through subject quality control methods.

Normal practice is to place a sample test bar that has undergone same manufacturing process that would be later on used for carrying the prescribed tests to ensure quality after heat treatment. Nevertheless, In-Situ Metallography, On line Ultrasonic and Magnetic Particle Testing are getting more popular. Even more sophisticated tests like residual stress measurement are demanded for certain critical components after heat treatment. Good database created based on the various test results will act as useful guide to solve any problem which may crop up from time to time. Nowadays, heat treatment shop requires hardness testing machine, metallographic facilities, softwares like image analyzer, micro-hardness testers and NDT facilities like UT and MP Testing equipments.

The Failure Analysis Team at TCR is jointly headed by Mr. Virendra Bafna (MD, TCR Engineering) and Mr. Paresh Haribhakti (MD, TCR Advanced Engineering). The TCR Advisory Board is often consulted on failure analysis projects.

Mr. Paresh Haribhakti is a B.E. (Metallurgy) M.E. (Materials Technology) from M.S. University, Vadodara. Mr. Haribhakti has done basic research in study of hydrogen embrittlement of steels and stainless steels. Mr. Haribhakti previously worked as trouble shooting metallurgist for India's largest fertilizers and petrochemicals complex, GSFC Ltd., Vadodara for nearly 10 years. His areas of interest are microstructure degradation of components exposed to high temperature and high pressure. He has working experience of more than 250 failure investigation cases of power plants, fertilizers, chemicals and petrochemicals industries. He has solved materials engineering problems and performed failure analysis on components from petrochemical plants, oil and gas transmission pipelines, offshore structures, ships, pharmaceutical plants, food processing equipment, gas turbine engine components, and weldments. Mr. Haribhakti investigates the available physical evidence, and performs the necessary tests to develop the most probable accident scenario. He simplifies complex engineering theory into easy to understand and useable concepts. He uses simple analogies, every day examples, and laymen terms to explain data and findings so clients, corporate executives, government officials, or attorneys may easily understand engineering concepts.

TCR has completed more than 800 investigation assignments, including 100 major projects on manufacturing or metallurgical failure analysis on ASME boiler and pressure vessels, Aircraft /Aerospace, Gas turbine engine components, Oil and gas transmission pipelines, Food processing equipments, Heat exchangers, Medical supplies, Automotive components, Refineries, Petrochemical plants, Offshore structures, Industrial machinery, Weldments etc.

TCR's failure analysis strength is in evaluating high temperature and high pressure failures. The Failure Analysis Team at TCR Engineering has experience in the materials, failure analysis, metallurgical, welding, quality assurance, and forensic engineering fields and is conducted by engineers holding advanced degrees in metallurgy, and mechanical, civil, chemical, and electrical engineering.

TCR Engineering works with our clients to plan the failure analysis before conducting the investigation. A large amount of time and effort is spent carefully considering the background of failure and studying the general features before the actual investigation begins.

In the course of the various steps listed below preliminary conclusions are often formulated. If the probable fundamental cause of the metallurgical failure becomes evident early on in the examination, the rest of the investigation focuses on confirming the probable cause and eliminating other possibilities. The metallurgical failure analyst compiles the results of preliminary conclusions carefully considering all aspects of the failure including visual examination of a fracture surface, the inspection of a single metallographic specimen, and the history of similar failures.

Procedure to conduct a Failure Analysis
Cause of failure is determined using state-of-the-art analytical and mechanical procedures and often includes simulated service testing. A combination of analysis and physical testing locates problems and provides recommendations for solutions.

Our initial step to perform failure analysis begins with visually studying the failed part and asking detailed questions regarding associated parts, plant environment and operational procedure. A complete evaluation sequence of the failure investigation steps are summarized as under:
•Collection of background data and selection of samples
•On-site evaluation and consulting services and Preliminary examination of the failed part
•Complete metallurgical analysis of failed material
•A thorough examination of the failed part including Macroscopic and Microscopic examination and analysis (electron microscopy may be necessary)
•If necessary tests also include Weld Examination, Case Depth, Decarburization Measurement, Coating/Plating Evaluation, Surface Evaluation and/ or Grain Size Determination
•Chemical analysis (bulk, local, surface corrosion products, deposits or coating and microprobe analysis)
•If necessary Tests to simulate environmental and physical stress that may have played a role in the failure
•Analysis of all the evidence. Formulation of conclusions and writing the report (Including recommendations).
