Abstract

Attention focuses on the heat propagation in metal polycrystals where the grain or subgrain size affects the strengthening—as a result of surface plastic deformation, for example. Effects associated with change in grain size are described by the Hall–Petch phenomenological model. A differential equation is obtained for the steady heat propagation in metals and alloys where plastic deformation within the statistical mean grain and close to its boundary modifies its size and shape.

晶粒尺寸变化的可变形多晶金属中的热传播

摘要

注意集中在金属多晶体中的热传播，在金属多晶体中，晶粒或亚晶粒的大小会影响强化，例如，由于表面塑性变形而引起的。Hall-Petch现象学模型描述了与晶粒尺寸变化相关的影响。对于金属和合金中的稳态传热，可以得到一个微分方程，其中统计平均晶粒内及其边界附近的塑性变形会改变其尺寸和形状。
