Publication number: 20120020829Abstract: Disclosed is a heat-resistant aluminum alloy including aluminum and two types of alloy elements which are combined while forming a homogeneous solid solution reinforcing phase. The disclosed heat-resistant aluminum alloy includes the alloy elements that form a homogeneous solid solution and do not have a solvus line with respect to aluminum as a matrix metal and, therefore, the formed homogeneous solid solution reinforcing phase does not react with aluminum even at a temperature up to 300° C., thus not becoming coarse or undergoing phase decomposition. Consequently, the disclosed aluminum alloy may have remarkably enhanced heat resistance.Type: ApplicationFiled: January 25, 2010Publication date: January 26, 2012Applicant: KOREA AUTOMOTIVE TECHNOLOGY INSTITUTEInventors: Si Young Sung, Beom Suck Han, Young Jig Kim, Bong Jae Choi, Yung Mun Ryu, Dong Ok Kim, Sang Ho Noh, Chang Su Hahn
