Abstract
Functional characteristics of bar semiproducts from shape memory NiTi alloys obtained by equal channel angular pressing, worm forging, and their combination are determined. The functional characteristics are measured and the phase transitions are studied under the conditions of three-point bending and thermocycling at a constant load. It is shown that the bar specimens subjected to warm forging at 350°C and to a combination of equal channel angular pressing at 450°C and warm forging possess the best level of functional properties.
