- EPS templates attaching a compressed powder disk on a surface that are mainly consisted of Ni-WC powders were prepared. High manganese molten steels were poured into the templates forming a surface alloyed sample using V-EPC process. After water quenching from 1050ºC, the microstructures of the steels were observed and analyzed using optical microscope, SEM and EDS. Macrostructural observation exhibits that the surface alloyed layer is dense and there are no obvious defects. Microstructural investigation shows that the steels from surface to core are consisted of two different parts, the surface alloyed layer and matrix. There are no any retained Ni-WC particles in the surface alloyed layer and the microstructures within this layer are composed of a small amount of fish-bone-like tungsten-rich fine carbides,a large amount of interdendritic carbides and dendritic austenite. Small amounts of carbide particles and net carbides at the grain boundaries in the matrix near the surface alloyed layer can be observed.
