Inhomogeneous Distribution of Second Phase Particles in Grain Oriented Electrical SteelsYang Li 1), Weimin Mao1, 2) and Ping Yang 1) 1) Department of Materials, University of Science and Technology...="ChDivSummary">The second phase particles were observed during the whole manufacturing process of conventional grain oriented electrical steels, exhibiting that the areal density of particles in the center......
. The microstructure analysis reveals that a part of Zr solves into the Mo matrix , which enhances the tensile strength of the alloys, while the other part of Zr forms oxide second phase particles. However, over-dose oxide particles would generate negative influence on the property of the alloy. Key words: Mo-Zr alloy; solid solution; second phase particles 钼由于具有熔点高,强度大,硬度高,导电导热性好,热膨胀系数低,耐磨损和抗腐蚀性能强及良好的抗热震性能和耐热......
