镁和镁合金由于具有重量轻、比强度、比屈服点、切削加工性能和吸振动性能好等优点,可以作为轻质目的的结构材料使用,但是目前的现状主要还是用于作为向铝合金中的添加元素。铝合金由于含有微量的氢气,所以我们可以看到,在压延后产生气孔,在铸造时产生微裂等现象,使其机械性能和化学性能显著降低,这是众所周知的事实。因此,我们进行了许多关于铝在精炼或铸造过程中尽可能减少氢含量的技术研究和关于除氢的研究。例如,我们能够看到许多关于向铝中吹进氯、氮、Cl_2—N_2混合气体、CCl_2F_2、CCl_2F_2—N_2混合气体以及用熔剂处理进行除气的研究报告。
Magnesium and magnesium alloys can be used as structural materials for light purposes due to their advantages of light weight, specific strength, yield point, machinability and vibration absorption. However, the current status quo is mainly used for the production of aluminum alloys Add element. It is a well-known fact that aluminum alloys contain a trace amount of hydrogen, so we can see that pores are formed after calendering, resulting in micro-cracking during casting, resulting in a significant reduction in mechanical and chemical properties. As a result, we have conducted many technical studies on the reduction of hydrogen content in aluminum as much as possible during refining or casting and on hydrogen removal. For example, we can see a lot of research reports on the blowing of chlorine, nitrogen, Cl_2-N_2 mixed gas, CCl_2F_2 and CCl_2F_2-N_2 into aluminum and degassing with flux.
