摘要

采用等离子体旋转电极法制备了T15高速钢（HSS）粉末。粉末颗粒中存在MC相（M主要是V相）、M2C相（M主要是W相）、α-Fe相和γ-Fe相。在103 ~ 105 K/s的冷却速率下，发现了初生枝晶和细胞晶。对于少量细粉颗粒如<；45 μm和少量粗粉颗粒，如>；250 μm的粉末颗粒分别达到105 K/s和103 K/s级，其他粉末颗粒达到104 K/s级。制备的PREP HSS粉末具有杂质含量低、流动性好、成分均匀、呈球形、无卫星粉等特点，有望取代商业气体雾化粉末，在超高性能致密HSS零件的生产中具有广阔的应用前景。

Preparation and characterization of a special high speed steel powder prepared by plasma rotating electrode process

A T15 high speed steel (HSS) powder was successfully prepared by plasma rotating electrode process (PREP). MC (M is V primarily), M₂C (M refers to W mainly), α-Fe and γ-Fe phases were observed in the powder particle. Both primary dendritic and cellular crystals were found due to the cooling rate of 10³-10⁵ K/s. The cooling rate for a small amount of fine powder particles such as < 45 μm and a few coarse powder particles such as > 250 μm achieves 10⁵ K/s and 10³ K/s class, respectively, and that of other powder particles attains 10⁴ K/s level. The PREP HSS powder displays low impurity content, good fluidity, uniform composition, sphericity and no satellite powder, which is expected to replace commercial gas atomization powder, and has promising application prospect in the production of dense HSS parts with ultra-high performance.

期刊介绍： The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
