The mechanical properties of chromium (Cr) and Cr-base alloys are reviewed, with particular emphasis on the ductility at ambient temperature and the strengths at high temperature. Analysis of rather scattered data and our recent results suggest that Cr-base alloy can be ductilized. greatly at ambient temperature and is quite capable of being strengthened to high levels at high temperature. New designs on composition would give high possibility to Cr-base alloys as structural materials used in high-temperature applications.
