中文摘要：金属热变形时涉及到组织晶粒度的变化，晶粒度对产品性能有直接关系，基于有限元法的产品晶粒度预报技术对控制产品质量具有重要意义。本文旨在推广晶粒度预报技术的应用，介绍了金属热变形组织晶粒度预报的典型应用及几种金属的再结晶演化模型。晶粒度预报技术能便于厂商控制产品质量，从而降低生产成本，会得到更广泛的使用。
英文摘要：Hot deformation involved in the metal grain size changes, which is directly rlated to product performance, forecasting the grain size based on FEM method is important to control the quality of product. This article aims to promote the grain size prediction technology, introduced typical applications of the hot deformed metal grain size forecast and evolution model of several metal. Grain size prediction technology can facilitate manufacturers to control product quality, reduce production costs, will be more widely used.
