Özet:

 

The microstructural and mechanical characterization of heat  treatable 6xxx (Al-Mg-Si-Cu based) wrought aluminum alloys was  studied.  The aim of this work was to produce a fine grained, high  strength 6xxx series aluminum alloy by adjusting the processing  conditions, namely deformation, solutionizing and aging.  Their  effects were investigated in terms of microstructure using SEM  analysis and mechanical properties by tensile tests and hardness  measurements.  The initial characterizations showed that Mg2Si and  (Fe,Mn,Cu)3SiAl12 were the primary particles observed in the  a -Al matrix.  Nearly 140HB hardness was obtained with  solutionizing at 530 °C and aging at 175 °C for 8 h, which was the  optimum treatment for obtaining peak hardness.  When shaping  (deformation) was concerned, 10% swaging before solutionizing  yielded lower strength and hardness as compared to the 40% swaging  due to lower strains finalizing partial recrystallization in the  10% swaged specimens.
