Phase transformations and order parameter in the shape memory alloys are sensitive to the stress applications and these stresses may cause important changes in crystallographic properties of alloys. In this study, five stage of compressive stress were applied onto two CuAlBe shape memory alloys and some morphologic and crystallographic changes were observed. The order parameters, a/b, of 18R martensite were increased by increasing stress application.
