Al 7075합금의 열간단조와 반응고 단조에 있어서 조직, 성형성 및 경도 특성 비교
Comparison of Conventional Hot Forging and Thixoforging of Al 7075 Alloy According to Microstructures, Formability and Hardness
초록
Conventional hot forging and thixoforging of Al 7075 alloy have been compared with respect to microstructures, formability and hardness. Two distinctive temperature-strain rate ranges for hot forging of Al 7075 alloy were observed from the results of simple compression tests with strain rates of 10-3∼101 sec-1 in the temperatures between
