| titleOfInvention | Creep-resistant and high-temperature-resistant cast aluminum alloy and manufacturing method thereof |
| abstract | A creep-resistant and high-temperature-resistant cast aluminum alloy belongs to the field of aluminum alloy manufacturing, and comprises the following mass percentages of Zn, 2.5-3.5% Mg, 2.0-3.0% Hf, 0.3- 0.6% Gd and 0.2‑0.5% Zr, the balance being Al and impurities. In the present invention, the precipitation phase growing along the prism surface can be generated by the addition of Hf or Gd elements, and the creep resistance of the alloy is improved. The combined action of Gd can form a large number of long-period ordered stacking structures, which can hinder the basal plane slip of dislocations, strengthen the matrix, and further improve the high temperature creep resistance of the alloy. In addition, the addition of Zr as a grain refiner can significantly Refine the grain and increase the yield strength of the alloy. |
