Effect of SiC Location on the Ablation of C/C-SiC Composites in Two Heat FluxesLei Liu,Hejun Li,Kui Hao,Xiaohong Shi,Kezhi Li,Chang NiState Key Laboratory of Solidification Processing,Northwestern Polytechnical University摘 要:How layer-segregated distributi......
the effect of Al2O3 content on heat transfer of Al-TRIP steel of mold fluxes, and SEM and XRD were used to analyze the crystalline phase of the slag films. The results show that the heat flux density...% to 30%. As the w(Al2O3)/w(SiO2) ratio increases, the heat flux decreases, and under this experiment condition, the CaF2 crystal phase precipitates. Key words: Al-TRIP steel; mold fluxes; Al2O3; heat......
