The oxidation of metals in high temperature

WebbDescription: High Temperature Oxidation and Corrosion of Metals, Second Edition, provides a high level understanding of the fundamental mechanisms of high temperature alloy oxidation. It uses this understanding to develop methods of predicting oxidation rates and the way they change with temperature, gas chemistry, and alloy composition. WebbThis temperature limit is based on creep properties rather than oxidation rate. r Austenitic Fe–Ni–Cr alloys, which form Cr2 O3 surface layers and have higher creep strength than ferritic alloys, are used to about 850 C. r Austenitic Ni–Cr alloys, which form Cr2 O3 surface layers, are used to about 950 C, which is the upper limit for oxidation protection by …
