Abstract
Nanostructured TiN/TiB2/Fe-Cr-Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form a uniform mixture of TiN and TiB2 within 2Â h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN and TiB2 are about 7 and 16Â nm, respectively, after 32Â h of milling. Through liquid phase sintering and optimizing the milling time, a compact body with almost full density could be obtained which has a narrow grain size distribution and exceptionally high hardness.
