Compound energy field with temperature and ultrasonic assisted forming process of titanium alloy and its applications
Based on high-temperature softening effect under temperature field and the volume effect and surface effect under the ultra-sonic energy field of the material,the compound energy field(CEF)with temperature and ultrasonic assisted forming method of titani-um alloy was proposed,which hoping to further improve the deformation ability and forming quality of titanium alloy sheet metal parts in hot forming by using the ultrasonic vibration energy field,or reducing the hot forming temperature of titanium alloy under the same form-ing quality.The forming principle and device of CEF with temperature and ultrasonic was introduced.The effects of CEF on the mechan-ical properties,microstructure,and friction between titanium alloy sheet and die were analyzed.On this basis,the method was applied to the forming process of bending of titanium alloy and complex curvature bending parts,and the forming quality and forming perform-ance were analyzed.Finally,the existing problems and development trends of CEF assisted forming process were summarized and pros-pected.
