Beyond Ni-Based Superalloys OverviewThis article presents an overview of publications on mechanical properties of chromium and chromium-based alloys, with particular emphasis on ductility at low temperature and strength at high temperature. Analysis of rather scattered data suggests that a chromium or chromium-based alloy can be ductilized at ambient temperature and is quite capable of being strengthened to high levels at high temperature. A new composition design and process would open new opportunities for chromiumbased alloys as structural materials used at temperatures up to 1,300°C.
