The increased stability of a coarse-grained and ultrafine-grained Ti49.15Ni50.85 shape memory alloy achieved with multiple martensitic transformations

Abstract

Abstract The influence of thermal cycling in the temperature range of B2-B19’ martensitic transformations on the TiNi alloy structure and properties are studied. The level of properties, obtained as a result of mechanical tests and measurements of microhardness, obtained in the process of thermal cycling, remains stable during soaking at room temperature in the TiNi alloy.
