Abstract

Hot compression testing of as-cast Ti60 alloy was carried out 970-1120 °C, 0.01-10 s1 and 30-75%. The fracture behavior of the alloy was investigated by light optical microscope, scanning electron microscope. The result shows that, at high strain rate and large height reduction, 45° transgranular fracture and longitudinal intergranular fracture are observed, which are confirmed to be transgranular cleavage brittle fracture and ductile fracture respectively. Moreover, the cracking degree increases with the increasing height reduction. Besides, the alloy deformed at high temperature exhibits a good ductility, whereas lots of longitudinal cracks occurs on its surface due to the brittle alpha-case formation. Consequently, the systematic analysis on the fracture mechanism for as-cast Ti60 alloy is vitally necessary for the optimization of processing parameters in its cogging process.
