ANALYSIS OF CHANGES IN MICROSTRUCTURE AND TEMPERATURES OF MARTENSITIC TRANSFORMATIONS IN TiNi ALLOY WITH DIFFERENT STRUCTURES
ANALYSIS OF CHANGES IN MICROSTRUCTURE AND TEMPERATURES OF MARTENSITIC TRANSFORMATIONS IN TiNi ALLOY WITH DIFFERENT STRUCTURES
DOI: 10.22184/1993-8578.2024.17.1.56.70
In the presented article studies were carried out of the influence of multiple martensitic transformations B2-B19’ on the structure and temperatures of transformations in different structural states of the TiNi alloy. It is shown that in coarse-grained, ultrafine-grained and nanocrystalline TiNi alloys, consistent changes occur in the microstructure and temperatures of phase transformations, with an increase in the number of thermal cycles to n=100 with rapid heating and rapid cooling to -196 °C. Transformation temperatures in the ultrafine-grained Ti49.15Ni50.85 state are more resistant to thermal cycling (TC) than in the coarse-grained state. The formation of martensite nanotwins in the nanostructural state after multiple thermal cycles was discovered.
