Fatigue behavior of over-aged 2A12 alloys in a vacuum environment;

Fatigue behavior of underaged 2A12 alloy in vacuum;

The fatigue behavior of nature-aged 2A12 alloy in air and vacuum at room temperature was investigated using a vacuum tension-compression fatigue testing machine.

The 2A12 alloy material was suffered from equal channel angular pressing(ECAP) in this experiment,using an ECAP die with the inner angle =90° and outer angle ψ=30°.

Application of thermo-mechanical treatment process on 2A12 aluminum alloy in craft of rotary extrusion;

Microstructure of Ultrafine-grained 2A12 Aluminum Alloy Pressed by Equal-channel Angular Pressing;

Study on the pore of vacuum electron beam welding 2A12 aluminum alloy;

Study on near-net-shape forming process of thin-wall shell body made for 2A12 aluminium alloy

The effects of different deforming temperature on the superplasticity of 2A12 aluminium alloywere experimented and discussed.

Put forward the near-net-sharp forming process of warm extrusion and warm stamping to manufacture the precision forgings for the thin-wall shell bodies made of 2A12 aluminium alloy.

The creep-damage parameters,localization of damage and the damage degree were obtained through the uniaxial tension creep test with duralumin alloy 2A12 in the condition of constant temperature(210℃) and different loads.
