【Abstract】 Effect of TIG welding procedure on the mechanical proper-tics of (Al, Cr) intermctallie compound is studied in this paper. The results show that the weldability of this alloy is very sensitive to the procedure variables and alloy composition. Improvement to the weldability is found by the addition of Nb element.更多还原
