反应球磨制备TiC/Cu复合材料

Preparation of TiC/Cu Composites Mterials by in Situ Reaction

采用反应球磨制备Cu/TiC复合粉末,然后进行压制和烧结,制备了TiC弥散强化铜基复合材料;描述了球磨过程中混合粉末的物理化学变化,研究了压制压强与材料致密度和硬度之间的关系。材料的显微组织表明,TiC在铜基体中有着均匀的分布。

TiC/Cu composite powder were fabricated by reaction milling,which were suppressed and sintered,then TiC dispersionstrengthen Cubased composites materials were fabricated.Physical chemistry diversification of composites were described during milling.Relation of pressing pressure,relative density and hardness were studied.Materials mircostructure indicated that TiC were distributing even in Cu group.
