| 摘 要： | 镁合金由于具有比强度高、比刚度高、电磁屏蔽性能强等特点，而成为当今研究的热点金属材料之一。但是加工变形能力差和不耐腐蚀的缺点限制了镁合金的发展。本文采用轧制复合的方法制备包铝镁板，提高镁合金的加工变形能力和耐腐蚀能力，并研究镁．铝复合机理、工艺制度对镁一铝结合的影响。研究结果表明：镁埠；轧制复合的机制主要是裂口机制，当轧制变形率超过临界值时，才能实现镁-铝良好的结合；轧后退火对镁-铝的结合强度影响很大，退火中镁—铝原子的互扩散有助于提高镁—铝的结合强度，但是中间相的出现大大降低结合强度。

| Abstract: | Though magnesium alloys are attractive materials for their high specific strength,high stiffness,excellent machinability and super damping capacity,development of magnesium alloys is restricted for their poor formability and low corrosion resistance.In order to resolve these problems,aluminum cladding magnesium alloys were fabricated by rolling-bonding method,the mechanism of rolling-bonding has been studied and the effects of various parameters in the processes on bonding strength have been analyzed.The re... |
