The Mechanical Property of Al7075 Rheology Material with Heat Treatment T6 to Eliminate Liquid Phase

용탕단조 공정을 응용한 액상이 제거된 Al7075 레오로지 소재의 T6 열처리 후 기계적 특성

Apply electromagnetic stirring system to making rheology slurry of Al7075. This experiment has important element which is the relation between solid fraction percent and melt temperature of Al7075. The rheology slurry of Al7075 eliminated liquid phase to include alloying element of copper and zinc by squeeze casting process. In result the most structure was composed entirely of globular primary $\alpha$. Used this material for this study. This study made a comparison of mechanical property according to heat treatment T6 at each melt temperature ($619^{\circ}C$ and $615^{\circ}C$). The microstructure and component are observed how heat treatment T6 weight with the mechanical property by SEM-EDS.
