摘要：

The objective of this study is to observe the thermoelastic coupling effect in a monocrystalline Cu-Al-Be shape-memory alloy. The orientation of the austenite crystal is measured by Microfocus X-ray texture analysis. Uniaxial cyclic loading is applied to the specimen at room temperature. Infrared thermography is used to capture temperature fields on the specimen surface. The approach consists in analysing the cyclic temperature oscillation of points located on the surface of the specimen. The study highlights first the significant difference between the thermoelastic couplings in austenite and martensite. Second the anisotropy of both phases, especially the martensite, is evidenced.
