TiN颗粒与基体界面干净

无反应层。

Abstract

SEM and XRD were employed to observe microstructure and phase constituent of TiN/Ti composites prepared by the smelting-casting method.The formation of TiN was analyzed.The results showed that continuous chain-like enhancement phase in the composites was uniformly distributed.SEM observation revealed that the morphology of TiN with the grain size of 2～8 μm is sharp angle sheet shape

sheet or bulk shape.There is no reacted layer between TiN particle and matrix interface.
