The Effect of Globule size on the Mechanical Properties in Semi-Solid Forming of Aluminium Alloys

알루미늄소재의 만용융성형 공정에서 구상화의 크기가 기계적 성질에 미치는 영향

One of the factors influences on microstructure of semi-solid product is forging pressure. Generally, the more forging pressure makes the more fine microstructure in semi-solid compression test. The microstructure and mechanical properties were investigated according to the forging pressure. The applied pressure is 110MPa, 140MPa and 170MPa, respectively. Heat treatment conditions also influence to the microstructure and mechanical properties of semi-solid product. T6 heat treatment was performed and the evaluation of microstructure and mechanical properties was investigated according to the aging time in T6 heat treatment.
