内容提示: Calculated ternary diagram of Ti–Al–Si systemC. R. de Farias Azevedo and H. M. FlowerThe phase equilibria between b (body centred cubic, bcc), a (hexagonal closed packed, hcp), Ti 3 Al–a 2 (hcp), andTi 5 Si 3 (hcp) in the Ti–Al–Si system have been ...
Since the driving force of (Al) is much stronger than (Si) nucleation and the Al–Si phase diagram is extremely asymmetric, the (Al) readily overgrow than eutectic (Si). The last one with longer length and more branching is more stable than the second type of eutectic (Si), since the...
,由于Al 2Si 渗层有很好的抗高温氧化,耐腐蚀,耐热性能,且Si 元素造价比P t 等贵金属低,因而在实际生产中倍受关注。K 4104是一种新型高温合金,现有文献中没有对其A l 2Si 共渗研究的相关报道。只有清楚地了解渗层的组织结构,才能更好地预测各种性能,指导实际生产。因此,本工作利用SE M ,X RD 和EP MA 对...
