Abstract: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.
Keywords:oxidation-reduction  regeneration  high density tungsten alloys  microstructure
