Simulation of Cooling Rate for CuFe15 Alloy by Single Roller Melt-spinning
Pages: 10-12
Year: Issue:  19
Journal: Hot Working Technology

Keyword:  Cu-Fe合金单辊旋铸冷却速度快速凝固;
Abstract: 建立了单辊旋铸凝固过程的数值分析模型,将真空室、冷却辊和样品带作为一个整体换热系加以考虑,以单辊旋铸CuFe15和CuFe10合金条带为模拟对象,通过采用一维傅立叶热传导方程描述热传输过程,结合热传导理论和凝固理论对热传导方程的数学解析求解,计算了单辊旋铸法制备Cu-Fe合金薄带的冷却速度,得到了铜辊制备200μm厚CuFe15合金薄带的自由侧在凝固结束时的冷却速度为1.5×106K/s.这与早期...
