Abstract

Statistical design of experiments was employed to assess the effect of mechanical alloying variables and the chemical binder, allyl hydridopolycarbosilane (AHPCS), percentage on the crystallite size of mechanically alloyed titanium silicide powder, and the microhardness of samples consolidated by chemical bonding. The results indicate that mechanically alloying the powder with higher milling time, higher milling speed, and lower ball-to-powder ratio, and consolidating with 7.5% AHPCS gives a combination of fine nanocrystalline size in the powder and good microhardness in the compact.
