摘要：
The inhomogeneous distributions of strain and temperature of a bicrystal Cu-Al-Mn shape memory alloy were investigated. A large strain gradient was observed near the grain boundary. During the compression test, the top and bottom grains underwent outward and inward out-of-plane deformations, respectively, which led to the formation of cracks. © 2020 Elsevier B.V.
