Comparison study on the annealing behaviors of dispersion strengthened copper alloys with different nanoparticlesGUO Mingxing,WANG Mingpu,LEI Ruoshan,TAN Wang,and JIN Peng School of Materials Science... of resistance to softening at elevated temperature is weaker than that of the Cu-Al2O3 alloys. However,when annealed at a temperature of 300-400°C,probably owing to the precipitation strengthening......
The Strengthening of Cu-15Ni-8Sn Alloy WANG Ming-Pu1,WANG Yan-hui1,HONG Bin1 (1.School of Material Science and Engineering, Central South University, Changsha China) 摘要:The microstructure... structure.The ordering structure includes two types of DO22 and L12 ordering. Their strengthening for the alloy is much stronger than that of spinodal decomposition. 关键词:Cu-15Ni-8Sn alloy; DO22 ordering......
. The strengthening contributions form solid solution strengthening, grain refinement, dislocation strengthening, precipitation hardening and dispersion strengthening were evaluated using standard equations. It was estimated that the maximum contribution was from grain refinement due to cryorolling followed by precipitation and dispersion strengthening. Key words: Al alloy; cryorolling; metal matrix......
