Atmosphere Influence on Sintered 316L Austenitic Stainless Steel Matrix Composites Reinforced with Intermetallic and Carbide Particles

摘要

This paper studies the change in properties of 316L stainless steel, depending on the nature and the volume fraction of the added reinforcement, and on the sintering atmosphere. Used reinforcements have been AlCr_2, Cr_2Ti, CV, SiC; and the amounts 1,5 and 3 vol./100. All materials have been manufactured mixing the Powders with a 0.6 wt-/100 of wax, compacted at 700 MPa, and sintered at 1230 deg. C. in order to analyze the Effect of sintering atmosphere, three different media were used: 75/100H_2-25/100N_2, pure H_2 and vacuum.
