THE SIZE DEPENDENCIES OF PROPERTIES OF Mo - W ALLOY OF EQUIATOMIC COMPOSITION

Abstract

Based on the parameters of the Mie–Lennard-Jones pair-wised potential of the interatomic interaction for Mo and W, the potential parameters for an equiatomic Mo - W substitution alloy were calculated. Size dependences for the equation of state, modulus of elasticity, coefficient of thermal expansion, isobaric heat capacity, surface energy and surface energy temperature derivative were obtained. Temperature dependencies of coefficient of thermal expansion and isobaric heat capacity for macro- and nano-crystals of Mo - W alloy were also obtained.
