In allusion to the problems existing at present, the portable aluminum alloy multi purpose rigs which are suitably used in soil and rock or their mixture formation, aluminum alloy drilling pipes, screw pump, screw air compressor and pneumatic hammer which consumes least air and whose diameter is least over China are researched and developed.

Aimed at the elimination of welding defects of hot cracks and welding deformation in site-welding assembly of LY12CZ aluminum alloy sheet with 2500 mm×6000 mm×2 mm,TIG welding process with Hammering and Rolling Technique(HRT)was adopted and investigated.

The effect of coating used to cover airplane on corrosion fatigue behaviour of LY12CZ aluminum alloy has been studied.

The evolvement of grain boundary morphology in commercial LY12CZ aluminum alloy with grain size between 19μm～21μm and non-pretreatment during superplastic deformation was observed and analyzed by optics microscope,SEM and TEM.
