一、前言钛在熔融状态下非常活泼,与各种耐火材料均发生不同程度的交互反应。这种反应是一个复杂的物理化学过程,钛铸件的几种主要缺陷——表面沾污、气孔、表面裂纹、夹杂等,大都是因之而产生的。因此,熔融金属与铸型交互作用的研究,对铸钛来说,比其它金属更 First, the preface Titanium is very lively in the molten state, with a variety of refractories have varying degrees of interaction. This reaction is a complex physical and chemical process, titanium casting several major defects - surface contamination, pores, surface cracks, inclusions, mostly due to. Therefore, the interaction between molten metal and the mold research, for titanium casting, more than other metals
