Abstract

Through molecular dynamics simulations, the mechanical responses of Cu50Zr50 metallic glasses were investigated during the indentation and scratching process. The effects of different temperatures were analyzed through the surface morphology, pile-up height, hardness, machining forces, resistance coefficient, and radial distribution function (RDF) diagram. The results indicated that the pile-up height and the hardness reduce as the temperature increases. The chip height is the lowest and the scratching groove is the smallest at the highest temperature of 900 K. The forces and the resistance coefficient curves are very close in the temperature range from 300 to 700 K, while they are lower at 900 K. The peak point of RDF decreases as the increasing temperature.
