Abstract :
TiB powders with submicrometer size were synthesized by mechanical alloying (MA) the mixture of elemental Ti and B powders in argon atmosphere using vibration ball mill. The ball-to-powder weight ratio was 10:1. The phase transition and the morphology of the powders during MA were investigated. Amorphization occurred after ball milling for 10h, after which the cubic TiB were formed and keep stable until the end.
