Dynamic Recrystallization Of Titanium Alloy Ti-6Al-4V During Thermal Deformation

Dynamic recrystallization of titanium alloy Ti-6Al-4V during thermal deformation

Titanium alloy ti-63al-4v is widely used in the field of aerospace, which has low thermal conductivity and low elastic modulus.At the same time, it is also a kind of difficult to machining material, in the process of machining, the high temperature and high pressure produced by the cutter-chip contact area accelerates the wear of the tool, the titanium element is easy to react with a variety of alloys and the elements in the tool, and the plastic deformation will lead to greater vibration between the tool and the workpiece.At present, the main method to solve the contradiction between the wide application of titanium alloy and the difficulty in machining is high speed cutting.Therefore, the study of the thermal deformation law and properties of titanium alloy ti-6al-4v under high temperature and pressure environment has become a research hotspot.

Dynamic recrystallization is a microstructure change phenomenon of pure metals, alloys, alloy compounds and non-metallic materials under high temperature and pressure.Titanium alloy ti-6al-4v will undergo dynamic recrystallization under high temperature and pressure, and the stress softening effect is obvious.
