The influence of cryogenic treatment on titanium alloys mechanical properties

Abstract

One of the most promising applications of cryogenic therapy is its ability to transform a wide range of materials. In this study, Titanium alloy (Ti6Al4V) was subjected to both deep and shallow cryogenic treatment. In addition to the anti-aging treatment, a deep cryogenic treatment was administered to the patient. Tensile tests were used to examine how cryogenic treatment affected the mechanical characteristics and ductility of Ti6Al4 alloy. According to this studies, cryogenic treatment expands flexibility of Ti6Al4V alloy. After 24 and 36 h, the deep cryo-treated samples had Uniform Plastic Deformation Region (UPDR) that were 5.3% and 8.3% greater than the untreated ones. However, after 36 h of cryogenic treatment, the yield strength of the material decreased by 2%. When subjected to a 36-hour period of severe cryogenic treatment, the alloy's phase ratio decreased from 8.1% to 5.6%, resulting in structural changes within the material. The unstable a phase gave rise to both stable and unstable phases. Experiments have shown that cryogenic treatment raises the flexibility and durability of Ti6AI4V alloy while also controlling the microstructure and lowering residual stress when performed at room temperature.
