Title:
SHAPE-MEMORY HARD ALLOY
Document Type and Number:
Japanese Patent JPS58167737
Kind Code:
A
Abstract:
PURPOSE: To obtain the titled hard alloy having large hysteresis, by making the phase (x) composed of a compound (Cu, Al, Ni) Ti exist in an alloy contg. the specified ratios of Al, Ni, Ti and Cu.
CONSTITUTION: In the alloy comprising 13W14.5% Al, 2W4% Ni, 0.1W5% Ti and the balance substantially Cu, 1W25vol% the phase (x) composed of a compound (Cu, Al, Ni,) Ti is contained at a ratio of 2×105W1×107 pieces/cm2 in average. Accordingly, the titled hard alloy having the large hysteresis of thermoelastic martensite transformation and the approximate temp. of transformation-inverse transofrmation is obtained.
