The morphology of chromium in chilled Cu-Cr alloys with 0.14% Cr has been studied. The results showed that eutectic Cr phase takes a fibrous shape, and pre-eutectic Cr is dendritic in the studied chilled Cu-Cr alloy. During solute treatment of the eutectic and super-eutectic Cu-Cr alloys, only part ...

在0.6 MPa的纯氢气氛中,采用金属/氢共晶定向凝固技术,制备得到不同Cr含量的GASAR多孔Cu-xCr合金试样(x=0,0.3%,0.5%,0.8%,1.0%,1.3%(质量分数,%)),并研究了Cr含量对多孔Cu-xCr合金气孔率和气孔平均直径的影响规律。结果表明:随Cr含量的逐渐增大,氢在...
