It is known that high temperature tensile strength increases with increasing Cr content in Cr containing heat resistant steels. Recently, however, it was found that long-term creep strength decreased with increasing Cr content in the heat resistant s

In advanced industrial gas-turbine systems, there has been a great demand for new single crystal (SC) superalloys with an excellent combination of high-temperature creep strength, hot-corrosion resistance and oxidation resistance. In this study, 12 n

The effect of S in steels on high-temperature steam oxidation resistance was investigated with respect to the content and the state in high Cr ferritic steels. The beneficial sulfur effect on high-temperature steam oxidation resistance was verified i

The solvus temperatures of the Laves phase were investigated in heat resistant 10Cr ferritic steels containing 2.3-4.7 mass% (Mo+W) and 0-1.7 mass% Re. The measured solvus data was approximately represented as a solvus curve in the pseudo-binary syst

In order to elucidate the Re effect on oxidation resistance, a high-temperature oxidation test was conducted with two groups of Ni-based superalloys. One group of alloys was characterized by 10mol%Al content (10-Al series). The other group of alloys

The dependence of steam oxidation resistance on the sulfur content has been investigated systematically in both ferritic and austenitic steels. It is found that the presence of impurity S, being considered as a harmful element in the past, improves s
