Abstract

The invention discloses a double-ultrasonic-assisted laser additive manufacturing device. The double-ultrasonic-assisted laser additive manufacturing device comprises a sample installation rack, an ultrasonic stirring system, an ultrasonic peening system and a laser additive manufacturing system. The laser additive manufacturing system and the ultrasonic peening system are arranged on the upper side of the sample installation rack, the ultrasonic stirring system is arranged on the lower side of the sample installation rack, the laser additive manufacturing system and the ultrasonic peening system are oppositely arranged, and a sample passes through the ultrasonic peening system after passing through the laser additive manufacturing system. According to the double-ultrasonic-assisted laseradditive manufacturing device, the double effects of ultrasonic stirring and ultrasonic peening are conducted on an anti-flaming titanium alloy in the laser additive manufacturing process, structure refinement and homogenization of the anti-flaming titanium alloy are achieved, and the alloy structure and the mechanical property can be effectively regulated and controlled.

Description

technical field [0001] The invention relates to the technical field of processing methods for titanium alloys, in particular to a dual-ultrasonic-assisted laser additive manufacturing device and method. Background technique [0002] Titanium alloys are widely used in turbine engines because of their small specific gravity, high specific strength, and high temperature resistance. Modern large engines with high bypass ratios use a large amount of titanium alloys in fan compressor components and other structures. However, conventional titanium alloys will burn under certain air pressure and temperature conditions, which will cause engine fire accidents (titanium fires) and affect the safety of aircraft. [0003] Flame-retardant titanium alloy is a special material developed to deal with the hidden danger of titanium fire. Its development is the most direct way to solve the problem of titanium fire. Two types of flame-retardant titanium alloys, Ti-V-Cr and Ti-Cu, have been dev...
