Effect of chlorine on the tensile behavior of reactive-sintered TiAl–Mn alloys

Ti–43.5 mol%Al–1.6 mol%Mn–2 vol.%TiB2–(0–600) mass ppm Cl alloys were fabricated by using a reactive sintering process, and tensile behavior of the reactive-sintered TiAl–Mn-based alloys having various chlorine contents was investigated. It was revealed that at room temperature tensile properties are hardly affected by the amount of chlorine. In contrast, at 1073 K, elongation decreased with increasing chlorine content, although yield strength was almost insensitive to the amount of chlorine.
