DOI:10.19476/j.ysxb.1004.0609.2019.09.16 粉末冶金高熵合金研究进展 刘 咏,曹远奎,吴文倩,宋 旼,张 伟,刘 彬 (中南大学 粉末冶金国家重点实验室,长沙 410083) 摘 要:高熵合金是一类由4,5种或者更多金属元素,以近等原子比例构成的新型金属材料,也称为复杂组元合金.由于其主要组元的非单一性,该类合金具有比传统合金特殊的性能,例如高的强度和韧性,优异的耐腐蚀性能和抗辐照性能等,但在制备方面,材料的组织均匀性以及缺陷控制也存在较大难度.粉末冶金与铸锭冶金相比,在复杂成分合金的元素分布均匀......
[23]和DETTENWANGER等[26]研究表面光洁度(Surface finish)分别为1 ?m和23 μm γ-TiAl合金纯氧和大气环境高温氧化行为,氧化初期光洁表面形成TiO2+Al2O3混合氧化而粗糙表面形成连续Al2O3氧化膜并在氧化膜/基体界面形成再结晶层(Recrystallization layer),因此光洁表面合金氧化速率比粗糙表面合金快2~3个数量级.目前关于表面状态对......
