METAL MATRIX COMPOSITE MATERIAL ENHANCED IN STRENGTH, DAMPING CAPACITY, RADIATION RESISTANCE AND CORROSION RESISTANCE

摘要

PURPOSE: To provide a metal matrix composite material enhanced in strength, damping capacity, radiation resistance and a corrosion resistance. ;CONSTITUTION: This metal matrix composite material contg. a shape memory element is the one in which the deformation stress (resistance) on the low temp. side before the inverse transformation of the shape memory alloy material element 1 produced by a rapid solidifying method or the like and imparted with high performance is lower than that of a mother phase metal 2 which is the amorphous one or the one constituted of nonocrystalline substance, and inversely, the shape memory recovering power and deformation stress (resistance) on the high temp. side after the completion of inverse transformation are higher than those of the mother phase metal. The metal matrix composite material is one in which the material performance of the mixed shape memory alloy element and metal mother phase produced by a rapid solidifying method or the like are made use for in particular at the time of producing this composite material, its radiant damage, resistance, corrosion resistance, specific strength and damping capacity are remarkably increased and applicable to the fields of nuclear engineering, space aviation, ocean development or the like.;COPYRIGHT: (C)1995,JPO
