High Temperature Oxidation Behavior of High Speed Steel for Roll in Water Vapor LIU Fang1,ZHOU Li1,SUN Da-le2,LIU Chang-sheng1 (1.College of Material & Metallurgy, Northeastern University, Shenyang 110004, China;2.BAOSHAN Iron & Steel CO., LTD. Technology Center, Shanghai 201900, China) 摘要:The oxidation behavior of high speed steel (HSS) was researched by high temperature thermo balance......
observed at Tp=295K. Tp is a transition temperature between metal and insulator phases[1, 2]. From the thermal magnetization, the Curie temperature of the sample is found to be Tc=303K, which is near... on the recent studies on the tunneling magnetoresistance model in the nanostructured materials[13] and percolation model near Curie temperature[13-16], we construct the percolative structure......
(i.e. the high Debye temperature); (4) the modest Curie temperature (TC) in the vicinity of room temperature to guarantee that the large magnetic entropy change can be obtained in the whole... intermetallic compounds [19-20]. The magnetic entropy change and Curie temperature of several magnetic material families at ΔH=5 T are shown in Fig.3, indicating that TC of the most binary and ternary......
