The Influence of Thermal Cycling on the Aging Processes and Physical and Mechanical Properties of a TiNi Alloy

摘要

—This work considers the influence of thermal cycling on the microstructure and aging processes of a TiNi alloy with a high Ni content relative to the stoichiometry. Changes in the microstructure during thermal cycling in coarse-grained and ultrafine-grained states as well as the characteristic features of the aging process at 400°C in preliminarily thermally cycled samples are shown.
