PROCESS FOR MAKING TI-NI BASED FUNCTIONALLY GRADED ALLOYS AND TI-NI BASED FUNCTIONALLY GRADED ALLOYS PRODUCED THEREBY

摘要

The present invention relates to Ti-Ni based functionally graded alloys easy in proportional control, which are made by cold working and annealing Ti-Ni based alloys under a predetermined temperature gradient. The thus processed Ti-Ni based functionally graded alloys have a shape memory effect and an ultra elasticity and at the same time, have a consecutive variation of shape depending on a temperature variation.
