摘要
研究了合金元素Ca和Ba对镁合金AZ63的燃点与熔体粘度的影响。结果表明:随着Ca或Ba量的增加,镁合金的燃点逐渐增大;随着温度的降低,镁合金熔体的动力粘度逐步增加,并且在963 K处降低;加Ba和加Ca的AZ63的燃点与粘滞性之间存在着某种关系,即粘滞性增大,镁合金燃点则提高。因此,可以通过测定不同的合金元素与镁合金的粘滞性的关系来判断该元素的阻燃作用,这是一条寻找有效阻燃合金元素的新思路。
Effects of alloying elements Ca and Ba on ignition temperature and melt viscosity of magnesium alloy AZ63 were investigated. Results indicated that with the increase of Ca or Ba content, ignition temperature of magnesium alloy was increased; Dynamic viscosity of magnesium alloy melt was increased gradually with the decrease of the temperature and dropped at 963 K; There existed a certain relation between ignition temperature and melt viscosity of magnesium alloy AZ63 containing Ca or Ba. viscosity increased, ignition temperature of magnesium alloy increased, too. So ignition-proof effect of an alloying element can be judged by testing relations between different alloying elements and viscosity of magnesium alloys and this is a new approach to research effective ignition-proof alloying elements.
