| Abstract: | The directional solidification technology is an important technology that can obtain a solidification structure with unidirectional orientation.The technology can control the lamellar orientation of the high-temperature structural materials——TiAl-based alloys.The paper describes the methods of the controlled lamellar orientation that is used widely at present.Moreover,it detailedly introduces that the used methods,the condition,the advantage and the disadvantage for the control technology of the lamellar orientation of TiAl-based alloys.Further research directions and new processing technologies are put forward. |
