Engineering, Northeastern University, Shenyang 110819, China Received 29 July 2013; accepted 30 September 2013 Abstract: A low-grade nickel laterite ore was reduced at different reduction temperatures. The morphology of metallic particles was investigated by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Experimental results indicate that the metallic nickel and iron......
Warm compaction powder metallurgy of Cu NGAI Tungwai Leo(倪东惠), WANG Shang-lin(王尚林), LI Yuan-yuan(李元元), ZHOU Zhao-yao(周照耀), CHEN Wei-ping(陈维平) (Guangdong Key Laboratory for Advanced Metallic... contents, different compaction pressures and temperatures in order to study the warm compaction of copper powder. Results show that too much admixed lubricant will lead to the squeeze out......
