Gamma Titanium Aluminide의 용접균열 감수성에 관한 연구
A Study of Weld Cracking Susceptibility of Gamma Titanium Aluminides
초록
Five cast gamma titanium aluminides, Ti-45~48%Al-2%Nb-2%Cr (nominal composition in at. %), were laser welded and their weld cracking susceptibilities were evaluated. Laser power, traversing rate and preheat temperature were systematically varied to generate a series of welds exhibiting a wide range of cooling rate (
