PURPOSE:To obtain an alloy having satisfactory workability and showing a significant shape memory effect in a state in which the atoms are irregularly arranged, by adding a specified amount of Pt to Fe. CONSTITUTION:Fe and 25-30atom% Pt are melted and the resulting molten alloy is cast into an ingot. This ingot is repeatedly subjected to cold rolling and process annealing three times to form a strip and this strip is heat treated to carry out final strain relieving. The strip memorizes the shape during the final strain relieving. The arrangement of the atoms is in an irregular state. |
