Mechanical, corrosion, and sliding wear behavior of intermetallics reinforced austenitic stainless steel composites
2009
The present work investigates the effect of supersolidus sintering and intermetallics (Ni₃Al, Fe₃Al) additions on the densification, mechanical, tribological, and electrochemical behavior of sintered austenitic (316L) stainless steels. The performances of the supersolidus liquid phase sintered (SLPS) compacts are compared with the conventional solid-state sintered (SSS) compacts of similar compositions. Correspondingly, the sintering was carried out at two different temperatures 1200 °C (SSS) and 1400 °C (SLPS). Supersolidus sintering results in significant improvement in densification, wear resistance, corrosion resistance, strength, and ductility in both straight as well as aluminide added composites.
