| 1 | 冷却速率对砂型铸造Mg-10Gd-3Y-0.4Zr合金凝固行为的影响(英文)显示文摘采用计算机辅助冷却曲线分析技术研究砂型铸造过程中冷却速率(1.4~3.5°C/s)对Mg-10Gd-3Y-0.4Zr合金凝固行为的影响。结果表明:随着冷却速率的提高,起始形核温度(Tα,N)由634.8°C升至636.3°C,再辉前最低温度(Tα,Min)由631.9°C降至630.7°C,形核过冷度(ΔTN)由2.9°C升至5.6°C,共晶反应起始温度(Teut,N)上升,固相线温度(T S)由546.0°C降至541.4°C,凝固温度区间(ΔTS)增加6.1°C。形核速率(N)的增加引起晶核数量的增加,从而降低α-Mg的平均晶粒粒径。相对于形核时间(ΔtN),形核过冷度(ΔTN)对α-Mg平均晶粒粒径的影响更大。温度增加值(T eut,N-T eut,G)与缩短的反应时间改变共晶反应进程,并且影响第二相的含量以及形貌。 | 庞松 吴国华 刘文才 张亮 张扬 Hans CONRAD 丁文江 | 2014 | Transactions of Nonferrous Metals Society of China2014，24，11： | 2 |
| 2 | 浇注温度对砂型铸造Mg-10Gd-3Y-0.4Zr合金凝固行为、组织与性能的影响(英文)显示文摘研究砂型铸造过程中浇注温度(680~780℃)对Mg-10Gd-3Y-0.4Zr合金凝固行为、组织与性能的影响。结果表明:随着浇注温度从680℃先提高至750℃再提高至780℃,α-Mg的形核过冷度从2.3℃提高到6.3℃后不再提高;α-Mg的平均晶粒尺寸先由44μm增加至71μm而后减小到46μm;共晶组织先由网格状转变为不连续的块状继而转变为大块的岛状;β-Mg_24RE_5相的体积分数增加,由颗粒状转变为短棒状;溶质富集的现象变得更加明显;合金的屈服强度由138MPa提高至151MPa,抗拉强度由186MPa提高至197MPa。750℃浇注的合金具有最佳的强度与延展性。断口形貌特征由准解理断裂转变为穿晶韧性断裂,并伴随着不同程度的缩松与氧化夹杂等铸造缺陷。相对于铸造缺陷、共晶组织以及溶质富集,α-Mg的晶粒尺寸是砂型铸造Mg一10Gd_3Y一0.4Zr合金屈服强度最主要的影响因素。 | 庞松 吴国华 刘文才 张亮 张扬 Hans CONRAD 丁文江 | 2015 | Transactions of Nonferrous Metals Society of China2015，25，2： | 2 |
