In current investigation binder comprised of paraffin wax, polyethylene glycol, stearic acid and low-density polyethylene are developed for moulding of composite powders of SS316L+WC-CrC-Ni, and sintered at 1200°C under hydrogen purged atmosphere. Composites are characterised with respect to rheological, thermal properties and microstructure by scanning electron microscopy, microhardness and density. Properties of sintering temperature and heating rate on the above properties have been evaluated to obtain a defect- free composite. © 2017 Elsevier Ltd. All rights reserved.

Introduction In present trend, the manufacturing process is developed for a large amount of small and complex parts with increased production rate to full fill demands of various products for modern day to day life. The manufacturing methods and processing of metal components have general limitations of traditional process for fabrication of metal components and it encouraging for finding alternative process. Hence alternative method for producing near net shape metal component is Metal injection moulding (MIM). The MIM is a mishmash of powder metallurgy and plastic infusion shaping procedure. MIM can produce low-cost products at large number, close tolerance and shape complexity, good mechanical properties, compare to other technologies since it eliminates secondary operations and also material damages while in case intricate geometries for numerous applications in today’s industry[1]. * Corresponding author.
