Evaluation of mechanical properties of ternary compound Cr_2AlC at 25-1000°C

摘要

Although Cr_2AlC exhibits attractive properties against oxygen atmosphere or corrosive salt at high temperature and was predicted to be a promising high temperature structural material based on calculated elastic properties , its strength and fracture behaviour under tensile stress at high temperature is still not available in the literature. This work is to study the high temperature behaviour of Cr_2AlC by using four-point bending test.
