单相合金平面凝固时固相平均成分的变化规律

Variation of Average Composition in The Solid Phase When a Single Phase Alloy Solidified With Plane Interface

本文从 Scheil 方程出发,推导了单相合金在固相无扩散、液相充分混和条件下,平面凝固时固裙平均成分随固相分数变化规律的数学表达式,并对此表达式进行了讨论.

When a single-phase alloy solidified with plane interface on condition that no diffusion at all in the solid phase,and the liquid phase mixed sufficiently,the average composition varies as the solid fraction increases In this paper,the expression for this variation is formulated and discussed based on the Scheil Equation.
