다국어 초록 (Multilingual Abstract)
The weldability of aluminum alloys made by the rapid solidification powder metallurgy was investigated by the hot cracking susceptibility test and microstructural examination. In this study, the optimum welding conditions for gas metal arc welding and electron beam welding processes were also established to weld aluminum alloys made by powder metallurgy. The weld beads of aluminum alloys insufficiently degassed showed nonuniform shape of beads, undercut and porosity in the weldments, while those of fully degassed aluminum alloys showed uniform beads and little porosity in the weldment.
Based on this study, it can be recommended that the hot cracking susceptibility of aluminum alloys made by powder metallurgy can be minimized by controlling the homogenization temperature and the degree of recrystallization, which produce the fine-grained microstructure.
