Influence of Al and Ti elements on the microstructure and properties of crnifecoalxtiy heas fabricated by ECAS

Abstract

CrNiFeCoAl<inf>x</inf>Ti<inf>y</inf> alloy series which fabricated by ECAS, were investigated in view of microstructure and microhardness properties. The differences were determined by changing Al and Ti ratios. The alterations on microstructure and microhardness values were determined by apply homogenization heat treatment. According to the results sintering process was successfully performed in a short time. Diffusion activities as well as interfusion of powders were observed in the microstructures following the sintering process. The bright phase has high Fe and Cr content, while the gray phase holds high Al, Ni and Ti content. Diffusion processes ended by homogenization and obtained more homogeneous distribution. The high microhardness values which obtained by sintering were raised further. © 2018 Elsevier B.V., All rights reserved.
