FIELD: metallurgy.
SUBSTANCE: invention relates to composite materials based on nitinol, and is intended for production of micromachine and machinery parts, medical instruments. Composite material based on nitinol comprises wt %: Cu - 5-10, Zr - 5-10, Ti - 36-44, Ni - 36-44, and at least one alloying element extracted from cobalt - not less than 5, yttrium - not less than 2, niobium - not less than 5, and boron - not less than 1, the rest. Material has a biphasic structure consisting of nitinol crystalline matrix phase and amorphous phase disposed along grain boundaries of the matrix phase.
EFFECT: material of diameter up to 5 mm with high strength and ductility with superelastic effect is obtained.
