摘要
The present invention is an Fe-Al-Si alloy powder, a method for chemical nitriding and in this mechanical and the crystallite size from coarse alloy powder by combining a method of grinding by ball milling energy ultrafine crystal size of 10~20nm a method of producing ultra-fine Fe-Al-Si powder using to gain comprises ultrafine Fe-Al-Si powder chemical and mechanical mixing and milling step. ; The present invention is found in about a process for producing an ultrafine powder from the Fe-Al-Si alloy powder, (a) obtaining a coarse Fe-Al-Si alloy powder; (B) to afford a, Fe-Al-Si-N alloy powder to nitriding treatment in order to increase the brittleness of the coarse Fe-Al-Si alloy powder; And (c) a step of obtaining the ultrafine powder of less than 1㎛ size and the Fe-Al-Si-N alloy powder-energy ball milling process. ; Ultrafine, Fe, Al, Si, powder, chemical, mechanical
