摘要
为了控制DIMOX工艺中复合材料的生长速度和体积,采用压差法补加合金,使剩余铝合金熔体的成分得到调整并与正在氧化生长的Al2O3/Al复合材料层保持连续接触。试验研究了补加合金成分对Al-3Mg-10Si合金氧化生长的影响作用。结果表明:补加纯Al或低Mg、Si含量的铝合金,能够降低合金熔体的含镁量,缩短材料生长前沿合金熔体成分到达Al2O3-(Al,Mg)两相区的时间,促进传质过程,加速材料生长,有利于获取较大体积的复合材料。
In order to control the growth speed and volume of the composite in the DIMOX, the method of added metal or alloy is adopted with the help of pressure head, with the result that the composition of the remanent aluminum alloy metal can be adjusted and continuously contacted with the growing Al2O3/A1 composite material layer obtained by directed metal oxidation growth. The effect of the additional alloy composition on the oxidation growth of Al-3Mg-10Si alloy was studied. The results show that the additional pure aluminum or aluminum alloy with low Mg and Si content can reduce Mg content of aluminum alloy melt, shorten the time of reaching Al2O3-(A1, Mg)phase zone of the alloy melt of growth forward position, promote mass transmission process, accelerate material growth, and be favorable to obtain more larger volume composite material.
