6000系铝合金中的含Mn相
|
摘要
6000系铝合金主要含镁和硅以及少量锰,锰在该系列合金中的作用是强化合金,使再结晶温度提高20～100 K等。铸态6000合金中的含锰相为β-AlFeSi;6061合金中的析出相为α-Al(MnFe)Si,经560℃均匀化处理2 h后,该合金的析出相为Al_(167.8)Fe_(44.9)Si_(23.9);6005合金中的含锰相晶体为简单立方结构。
6000 series aluminum alloys contain primarily such elements as magnesium, silicon, and a small amount of manganese, and manganese serves to strengthen the alloys and to increase their recrystallization temperature by20 to 100 K. The manganese-containing phase in the as-cast 6000 alloy is(3-AlFeSi. The manganese-containing precipitated phase is α-Al( MnFe) Si in the 6061 alloy,and Al_(167.8)Fe_(44.9)Si_(23.9) in the 6061 alloy homogenized at 560℃ for 2 h. The crystal structure of manganese-containing phase in the 6005 alloy is primitive cubic.
