Microstructure and Mechanical properties of the as-cast and equal channel angular pressed(ECAPed)Mg-Al binary alloys with different Al content(10 wt%~25 wt%)were investigated.

The process of brushing Ni-P compound layer on Al-Mg alloy surface;

Welding pipe of Al-Mg alloy;

The main materials of the ship made of aluminium are mainly used the hull planks of Al-Mg alloy (5083H226/H321) and the sec- tions of Al-Mg-Si alloy(6082-T2),and the welding technology for the hull is auto and/or semi-auto MIG welding as well as TIG welding(to weld tubes).

Although the Al-Mg alloys have good anticorrosion,excellent formidability and weldability,which are widely used in the military and civil ships,their strengths are not very high.

Dephosphorization of High Vanadium Steel and High Chromium Steel with Aluminium-Magnesium Alloy;

The deoxidation ablity and desulphurization ablity of aluminium-magnesium alloy,changing inclusion properties of aluminium-magnesium alloy,transforming inclusion characters of aluminium-magnesium alloy and removing inclusion are analysed in thermodynamics.

Under the same conditions,the Al-Mg alloys surface treatment was performed by the microarc oxidation with different components of electrolytes.
