本文系统研究了93W-Ni-Fe-Co(Mn)合金切屑由氧化还原法所得回收粉的化学纯度、粒度、主量组分的存在状态及由此回收粉所制再生合金的显微和断口形貌,W晶粒与粘结相的组成,主要杂质元素的含量、结合状态与分布,同再生合金力学性能之间的关系。
The mechanical properties of regenerated W-alloys relating to thechemical purity and size of reclamation powders of 93W-Ni-Fe-Co (Mn) alloychips, the structure of main constituents of the powders, as well as microstructureand fractograph of regenerated W-alloys made by the reclamation powders, compo-sition of W particle and binder phase, content, structure and distribution of mainimpurity elements have been studied by means of optical microscope, SEM, XRES,XRD, TEM, AES and chemical analysis. The feasibility of oxidation-reductionprocess for reclamation and the possibility of practical application of regeneratedW-alloys have been discussed.
