雾化喷射沉积成形中沉积体内的凝固过程(Ⅰ)──理论分析

Analysis of Solidification Behavior in Spray Deposited Preform (Ⅰ)──Theoretical Analysis

采用“虚拟”凝固层的概念，通过对沉积坯内凝固过程的温度分布、凝固时间、虚拟凝固层厚度等参数的理论分析，建立了相应的理论模型，并求得了这些参数的数值解．

A concept of 'Vertual' solidification layer is applied to establish a theoreti-cal model to simulate the temperature distribution, solidification time and thickness of thevertual solidication layer during the solidification process in preform during spray forming.Using mathematical simulation methods, these factors mentioned above are solved.
