High-entropy alloy welding wire for TIG (tungsten inert gas) welding of titanium and steel and preparation method
The invention discloses a high-entropy alloy welding wire for TIG (tungsten inert gas) welding of titanium and steel. The high-entropy alloy welding wire comprises, in total atomic percent of 100%, 30-33% of Zr, 8-12% of Cu, 15-18% of Fe, 20-24% of Ni and 20-24% of Be. The invention further discloses a preparation method of the high-entropy alloy welding wire for TIG welding of the titanium and the steel. The amorphous high-entropy alloy welding wire is fine in smelting and machining property and low in manufacturing cost, and the preparation method and the process of the welding wire are simple. The titanium/steel TIG welding process by the amorphous high-entropy alloy welding wire is simple, the welding wire is effectively matched with the titanium and the steel, a welding zone is crack-free, a welding line is basically a single-phase solid solution texture, and the general mechanical performance of a joint is high. 1. For titanium and steel a TIG welding of high-entropy alloy wire, characterized in that comprising the following ingredients according to the atomic percentage composition: total percentage is 100%, Zr is 30-33%, cu to 8-12%, Fe is 15-18%, Ni is 20-24%, Be to 20-24%. 2. A the method for the preparation of high-entropy alloy wire according to Claim 1, characterized in that in accordance with the following steps to implement: Step 1, using ultra-high-vacuum arc furnace melting mother alloy According to the atomic percentage, wherein the Zr 30-33%, cu to 8-12%, Fe is 15-18%, Ni is 20-24%, Be to 20-24%, the total percentage is 100%, will be converted into the above-mentioned atom percentage of mass percentage, the weighted percentage according to the quality of the high purity metal, the above-mentioned component mix, for compacting bases; the blank in the ultra-high-vacuum arc furnace for melting, the parent alloy prepared; Step 2, using metal spins the achievement technology, the upper step the obtained mother alloy re-melting, the quench spins twists the wheel fast solidifying preparation into the amorphous high-entropy alloy wire, is formed. 3. Process for the preparation of high-entropy alloy wire according to Claim 2, characterized in that the step 2 in, the speed control in wheel line- spins the achievement 5-8m/s.
