| Abstract: | By means of isothermal forging forming of some shaft-hubs used 2A14 aluminium alloy, the die-designing, the material specification, the forging temperature and the heat treatment parameters were searched for the influences on mechanical properties and microstructure of it, and the contrast of the mechanical properties and mierostructure of isothermal forging with usual methods were also discussed. The mechanical properties of isothermal forging of 2A14 aluminium alloy were higher and the grain microstructure was relatively thinner compared with common forging. Furthermore, this forging method of shaft-hub producing have the advantages of technologically stabilizing, fast-shaping, high usage of material and high production efficiency, important engineering value and promising future. |
