Abstract

PURPOSE: To manufacture an NiTi shape memory alloy material having reversible shape change characteristics and small hysteresis by specifying the Ni content in an NiTi alloy as stock, conditions during heat treatment, the extent of strain produced during final shape memory heat treatment, and the cold working rate.
CONSTITUTION: A hot worked material of an NiTi shape memory alloy consisting of 50.0W60.0wt% Ni and the balance essentially Ti is cold worked at ≤60% working rate within the range defined by a line connecting point A (50.0% Ni content, 60.0% working rate), point B (50,0% Ni content, 15.0% working rate), point C (56.0% Ni content, 1.0% working rate) and point D (60.0% Ni content, 1.0% working rate). the cold worked material is subjected to soln. heat treatment at ≥650°C for ≥1min and 0.2W5.0% strain is produced in the material by final shape memory heat treatment at 300W650°C for ≥1min. Thus, a shape memory alloy material having desired characteristics is stably manufactured in such simple treatment shapes.
