摘要: This paper used numerical and experimental methods to investigate the mechanical properties of amorphous NiAl alloys during nanoindentation process. A simulation was performed using many-body tight-binding potential method. Temperature, plastic deformation, elastic recovery, hardness were evaluated. The method based on measurements, allowing a precise prediction Young's modulus values for comparison with results. indentation results showed significant increase recovery increasing Ni content. Furthermore, that are in good agreement Adhesion test at room temperature is also described this study.
