| Abstract: | The heat-resistant Al alloy has a good prospect for application, and progress has been made in alloy design and its fabricating technologies. The main technologies in improving the heat-resistant properties of Al alloy include adding alloy elements to precipitate stable strengthening phases with a high melting point from aluminum alloy and achieving the precipitates in dispersed distribution by solidification control, heat-treatment and other technological measures to stabilize the matrix and strengthen the grain boundary. Currently, the top priority is to lower the manufacturing cost. |
