摘要：

Mechanical alloying for Ti-Al-Cr mixture of elemental powders was performed by a vibrational ball mill in Ar atmosphere under reduced pressure. The effect of Cr addition for mechanical alloying process was studied by X-ray diffraction and SEM. The microstructure of mechanical alloyed Ti-Al-Cr alloy after sintering was studied by optical microscope and EPMA. An addition of Cr made particle size of mechanical alloyed powder fine and sintering easy. Mechanical alloyed Ti-Al-Cr alloy containing 4 to approximately 6 mass%Cr had needle-like crystals of Ti3Al after sintering at 1673 K for 1.2 ks.
