Abstract
The influence of ingot homogenization on the microstructure of 3003 aluminum alloy extrusion was investigated. When precipitates in the ingot were almost smaller than 0.1 μm size and precipitated with high density, extrusion became fiber structure. But the thermal stability of fiber structure was depended on the form of constituent particles in the ingot. When constituent particles covered the cell boundaries, extrusions became fully fiber structure. On the other hand, when constituent particles transformed into necklace structure and became smaller during homogenization, the surface of extrusions recrystallized and became abnormal grain growth structure. When precipitates in the ingot were almost bigger than 0.1 μm size, precipitated uniformly and matrix had much solutions, extrusions recrystallized easily so that extrusions became fine recrystallized structure. When precipitates bigger than 0.1 μm size were less and they did not disperse uniformly, extrusions became bigger recrystallized structure.
