Establishment of hydrogen measurement system for magnesium alloy melt XU Si-xiang(许四祥), WU Shu-sen(吴树森), MAO You-wu(毛有武), AN Ping(安 萍) State Key Laboratory of Material Processing and Die &..., a rapid and reliable measurement system for hydrogen content in magnesium melt was set up with CPU controller and electric circuit. With this instrument, measurement experiments were carried out......
chloride solution showed that the corrosion potential shifted to more negative values with additions of Sb, Bi and Sr, respectively. Corrosion immersion tests also revealed that the element additions have a detrimental effect on the corrosion rate of alloys, due to the increase of boundaries between the Al and eutectic Si phases. Key words: aluminium die cast alloy; melt treatment; mechanical......
Development of magnesium composite alloy by a new method combining B2O3 addition and melt stirring BU Le-ping(卜乐平)1,2, S. TANAKA1, M. TSUSHIDA3, S. ANDO3, H. TONDA3 1. Graduate School... Abstract: For developing high performance magnesium alloys, a new method in combination of B2O3 addition and melt stirring was applied. When 0, 3%, 6% and 12%( mass fraction) B2O3 was added into pure Mg......
