Effect of Strain on Room Temperature Compression Deformation Mechanism of Ti-55531 Alloy after Two-phase Solution Treatment AITranslate
Abstract AITranslate
Room temperature compression deformation experiments of Ti-55531 alloy after two-phase solution treatment were carried out using Gleeble3800 thermal simulation test machine and 6.3 MN forging simulator.SEM,XRD and TEM were used to characterize the deformed microstructure.The effect was studied of strain on room temperature compression deformation mechanism of Ti-55531 alloy after two-phase solution treatment.The results show that the microstructure of Ti-55531 alloy after two-phase solution treatment consists of primaryαp phase and residualβr phase,andαp phase has lower hardness thanβr phase.When the engineering strain of room temperature compression is 8%~10%,the dislocation of the alloy is mainly concentrated inα_p phase.As the strain increases,the dislocation density inα_p phase increases.When the engineering strain increases to 20%,a large number of dislocations are clustered atαp/βr phase boundary,serious dislocation accumulation and dislocation entanglement are formed inαp phase,and the number of activated slip systems inβr phase is also gradually increased.When the engineering strain increases to 30%,dislocation accumulation and dislocation entanglement also occur inβr phase.When the strain continues to increase and the engineering strain increases to 60%,the equiaxed primaryαp phase is elongated along the deformation direction,and a large number of dislocation cells appear in bothαp phase andβr phase.
