Preparation of Nano-crystalline WC-Co-RE Powder AITranslate
Abstract AITranslate
The WC-Co-RE powder was prepared by high-performance ball milling.The structure,morphology and phase change of nano-crystalline powders were analyzed by means of XRD (x-ray diffraction),SEM (scanning electron microscope) and DTA (differential thermal analysis).The results showed that the nano-crystalline powder with grain size of 8.45 nm was obtained by 45-h ball milling and addition of trace rare earth was effective to diminish the grain size of the powder.The grain size of rare earth doped powder became two times smaller than that of the undoped powder,and the decrease trend of the grain size of the powder accord with linear regression equation after 25～45 h-ball milling.The XRD peak of Co phase disappeared after 25-h ball milling.A sharp peak of heat release at 597 ℃ was emerged in DTA curve.Upon the solidification,the powder exhibits fine grain size and good mechanical property.
