and plates inter-connected with cotter pins in the present job-carrier design. This choice ensures the reliability and stability of the job-carrier while navigating thermal cycles and the demanding operating conditions within the furnace. Furthermore, the design of a lightweight and demountable job-carrier gains significance due to the limited load carrying capacity of 500 kg within the furnace. The focus on a light weight design facilitates efficient utilization of the furnace's work zone, while the demountable nature allows for easy assembly and disassembly. Thus, the use of TZM alloy in the job-carrier design, the incorporation of standard structural components and the emphasis on light weight and demountable features collectively contribute to the job-carrier's weight reduction to 55 kg and cost reduction by 70% including material and manufacturing cost. Acknowledgement We would like to express our sincere gratitude and appreciation to all those who contributed to the successful completion of this work. We wish to express our sincere gratitude to the vacuum furnace team at RRCAT (Raja Ramanna Centre for Advanced Technology) for their generous support. Their expertise and guidance in utilizing the furnace for brazing, diffusion bonding, and heat treatment were invaluable in the development of the job-carrier.
