A Novel Approach for Determining Critical Fracture Strain of a near Alpha Titanium Alloy during Hot Compression Deformation

Abstract:

A novel high-speed photography is introduced to determine the critical fracture strain of a near alpha titanium ally during hot compression deformation. This method precisely captures the nucleation site and propagation process of cracking, and thus is an excellent method to represent dynamically the hot-deformation fracture. Compared with the traditional way, it can significantly decrease the number of trials and improve the accuracy. Based on this method, the critical fracture strain is measured, and a critical fracture model is developed.
