High Temperature Fatigue Behavior of A356 and A319 Heat Resistant Aluminum Alloys
A356 및 A319 내열 알루미늄 합금의 고온 피로 변형 거동
Abstract
In this study, fatigue samples were prepared from cylinder head parts that are actually used in domestic (A) and foreign (B) automobiles; high-temperature, high-cycle, and low-cycle fatigue characteristics were then evaluated and compared. A study on the correlation between the microstructural factor and high temperature fatigue characteristic was attempted. The chemical compositions of the heat resistant aluminum alloys above represented A356 (A) and A319 (B), respectively. The result of the tensile strength test on material B at
