对超磁致伸缩材料退火过程中的物质传输和相变进行了研究。结果表明：两个主要过程协调发生：基体相由发达的枝晶转变为粗大的柱状晶;富稀土相熔化并被挤出棒材。这两个过程是获得优异磁致伸缩性能的必要条件，蘑菇状晶体的生长是这两个过程完成的重要标志。
A study was carried out on the matter transmission and phase transition in annealing process of GMM. It is show that both the primary processes occur in coordination: the base phase transforms from developed dendrite into thick column crystal; the rare earth-rich phase is melted and extruded out of the bar. The two processes are necessary for get excellent magnetostriction, and growing of the mushroom form crystal is an important sign for full processes.
