Research of Mechanical Properties of Ni-Ti-Nb Alloys on Low Temperature and Restriction Behavior
Mechanical properties of Ni-Ti-Nb alloys taken by the different heat treatment processes and constraint reply conditions at low temperature had been tested respectively to analyzing the variation law. The results show that the mechanical properties of alloys under vacuum heat treatment is much better than that of alloys under cold-drawn and the general heat treatment. Additionally, there is not clear the yield plateau on the stress curve of constraint reply samples whoseσ0.2 is far greater than σs of unconstraint reply specimens, and the tensile strength is higher than the latter also.
