To improve the strength,hardness and heat resistance of Mg-Zn based alloys,the effects of Cu addition on the as-cast microstructure and mechanical properties of
The demand for high performance cast aluminum alloy components is often disturbed by increasing impurity elements,such as iron accumulated from recycled scraps.
Strontium was introduced into CeO2-ZrO2 mixed oxides (CZ) by doping and impregnation methods,and then Pt was impregnated on the Sr-modified CZ to obtain the cat
In-situ ZrB2/AZ91D magnesium matrix composite was successfully synthesized with Al/K2ZrF6+NH4BF4 by means of Direct Melt Reaction.The fabricated ZrB2/AZ91D magn
A navel electron beam welder (EBW) power supply was developed.Compared with the traditional 3-phase control 12-pulse rectifying supplies,it requires a much lowe
