High Temperature Deformation Behavior and Strengthening Mechanisms of Heat Resistant High Entropy Alloys
Abstract
High entropy alloys, HEAs, which consisted of multicomponent elements and often stabilized as a single solid solution due to a high configurational entropy effect, have shown extraordinary mechanical properties. Due to these unique and excellent properties superior to those of conventional alloys, HEAs become promising materials for structural applications. In particular, several specific compositions of high entropy alloys have exhibited higher strengths at elevated temperatures compared to those of Ni base superalloys. Although a few HEAs have shown improved high temperature mechanical properties, the researches on heat resistant HEAs are still in the early stage and raise questions regarding the unexplored fundamentals on alloy design, deformation behavior and strengthening mechanisms at elevated temperatures. This proposed research will focus on the understanding of the high temperature deformation
