通过对宏观上致密、适中、疏松的海绵钛试样进行微观组织结构分析,认为虽然海绵钛坨各部分宏观结构不同,但是其与自身的微观组织、相及晶粒度无关,海绵钛坨宏观结构的疏松和致密只是一个纯物理量的概念;还认为海绵钛质量的优劣,不仅反应在其杂质含量多少和布氏硬度高低上,还与其组织结构(致密性)有很大关系,两者之间没有必然的联系,并且探讨了还原蒸馏工艺对海绵钛结构的影响。
By analyzing the microstructure of the macroscopically dense, moderate and loose sponge titanium samples, it is concluded that although the macroscopic structure of the sponge titanium lumps is different from each other, it has nothing to do with its own microstructure, phase and grain size. Loose and compact structure is only a concept of pure physical quantity; also consider the advantages and disadvantages of sponge titanium quality, not only the reaction in the amount of impurities and Brinell hardness level, but also with its organizational structure (dense) has a great relationship between the two There is no necessary connection between them, and the effect of reductive distillation process on the sponge titanium structure is also discussed.
