Landmark Research Contribution:
Dr. Ashok Kumar Ray is a specialist in Materials Science and Technology & Metallurgical Engineering with specific emphasis on Energy conservation and Component integrity evaluation. His contributions in the area of Life Extension Studies of Aged Components in Power Plants and Petrochemical Industries, High Temperature Materials covering Advanced Ceramics, Development of High Temperature Creep Resistant Mg-alloys and creep behaviour of modified squeeze-cast AZ91 magnesium alloy for power train applications, Development & Thermo-Mechanical Characterization of Thermal Barrier Coatings (TBCs) for Aero & Gas Turbine, Titanium Aluminide Coatings on Ti based alloy for Kaberti Marine Gas Turbine Applications respectively, have been outstanding. The output of his research on TBC coated superni C263 is applicable to Kaveri Engine Project. NTPC Plant Dibiyapur is using bond coated blades, with Udimet 520 superalloy as substrate for better efficiency and serviceability, based on recommendations made as a result of his collaborative research programme with NTPC. The life of turbines increases significantly due to thermal barrier coated components (combustor liners, vanes and blades). It ultimately leads to saving of high value turbine material by extending its life. This in fact improves reliability of power generating system, leading to safety and better quality of life. The high quality of his publications and the projects executed by him speak very highly of his contributions. He has an excellent academic and research background.BPCL Mumbai has already replaced the entire CCU Reactor Unit for safety reasons in April – May 2014, in order to avoid loss of life, based on the recommendations [4,95,96] from the collaborative research with them since the last 25 years on “RLA of service exposed CCU reactor, stripper vessel and FPU-D1 column shell plates”. Mangalore Refinery and Petrochemicals (ONGC) is also replacing the pig tail porion of their Reformer unit based on the recommendations made from the collaboration with MRPL Mangalore on “RLA of hydrogen reformer ,pig tail, crude distillation heater and visbreaker tubes” during their plant shut down for safety and economic reasons. The output of Dr. Ray’s research on “Influence of Saline Environment on the creep rupture life and low cycle fatigue behaviour of Superalloy Nimonic- 263” is applicable to Kaveri Marine Gas Turbine project. Thus Dr. Ray’s work has made significant contributions in energy saving and is highly futuristic. It contributes in a large measure to National wealth and technological well being.
