Shear-thinning behavior of the CaO–SiO2–CaF2–Si3N4 system mold flux and its practical applicationYing Xu1,Zhi-peng Yuan2,Li-guang Zhu2,Yi-hua Han2,Xing-juan Wang21. Hebei Provincial Key Laboratory...="ChDivSummary">Satisfying the mold-flux performance requirements for high-speed continuous casting necessitates the development of a new non-Newtonian-fluid mold flux with shear-thinning behavior, i.e., a mold......
Influence of flux treatment on the glass forming ability of Pd-Si binary alloysNa Chen, Kefu Yao, and Fang Ruan Key Laboratory for Advanced Materials Processing Technology, Ministry of Education... spinning and B2O3 flux treatment. A compari- son between the ribbons prepared from the fluxed ingots and the non-fluxed ones has been carried out. The result reveals that after fluxing treatment......
