摘要

研究了铸轧坯料和均匀化退火态的Al-0·8Mn-0·5Fe系合金的显微组织

分析出均匀化退火温度对显微组织的影响及温度和组织间的变化规律。结果表明:经过540℃×4h的热处理后

材料析出大量细小弥散状分布的第二相粒子

合金可获得较均匀的显微组织。在540℃之前的均匀化处理

铸轧板坯晶粒几乎没变化

经580℃均匀化处理后

晶粒明显长大

是均匀化前的几十倍。

Abstract

Microstructures of as-cast and homogeneously annealed Al-0.8Mn-0.5Fe alloy sheet have been observed

and effects of homogeneously annealing temperature on microstructure of the alloy sheet have been approached. The uniform microstructure in alloy can be observed due to amounts of dispersively distributed fine secondary phase precipitated from the alloy after annealing at 540 ℃ for four hours. The change of grain size in the casting-rolling sheet is absent with homogeneously annealing temperature lower than 540 ℃ while the grain remarkably grows with homogeneous annealing at 580 ℃

which is ten times more than that of ones before homogeneous annealing treatment.
