摘要: Abstract In this study, a novel type of rotating disc unit was designed and constructed used to produce rapidly solidified AA2014 alloy powders. Copper stainless steel were as the material temperature cooling water selected 0°C 18°C. Effects production parameters, such material, temperature, superheat liquid metal speed on microstructure rate powders, have been investigated.The produced powders cellular changed cellular-dendritic with increasing powder size. It found that rates relatively higher using copper temperature. The results indicated 25 μm estimated 1·01×106 K s-1 9·02×105 for 18°C temperatures respectively. Decreasing also increased coo...
