Process for manufacturing hot-forged parts made of a magnesium alloy |
摘要 |
A process for manufacturing a process for manufacturing a part made of a magnesium alloy is disclosed. The process includes a step of forging a block of the alloy followed by a heat treatment. The alloy is a casting alloy based on 85% magnesium, and containing, by weight: 0.2 to 1.3% zinc; 2 to 4.5% neodymium; 0.2 to 7.0% rare-earth metal with an atomic number from 62 to 71; 0.2 to 1% zirconium. The forging is carried out at a temperature above 400° C. In particular the temperature is set between 420 and 430° C. and the forging step comprises a plastic deformation carried out at a slow rate. The process allows one to produce parts such as elements of casing for aeronautical machines, operating at a temperature of around 200° C. and having good aging properties. |
