Analysis of Solidification Behavior in Spray Deposited Preform (Ⅰ)──Theoretical Analysis
-
摘要: 采用"虛擬"凝固層的概念,通過對沉積坯內凝固過程的溫度分布、凝固時間、虛擬凝固層厚度等參數的理論分析,建立了相應的理論模型,并求得了這些參數的數值解.Abstract: A concept of "Vertual" solidification layer is applied to establish a theoretical model to simulate the temperature distribution, solidification time and thickness of the vertual solidication layer during the solidification process in preform during spray forming.Using mathematical simulation methods, these factors mentioned above are solved.
