Abstract
Cold-rolled Co-Cr-Ni alloy (Elgiloy) and Co-Ni-Cr alloy (SPRON 510) can be considered for diaphragm valve materials in gas valve systems. In this study, the effect of direct aging (DA) heat treatment on the tensile properties of Co-based alloys was investigated and the influence of microstructural changes on the tensile behavior.....
