摘　　要：从铸铁的组织机构及力学性能出发,导出了铸铁在拉伸与压缩过程中温度与应力之间的关系式,阐明了铸铁拉伸时温度下降的反常现象。The relationship between the temperature changing and stress-stretch of cast iron is derived. From its microstructure and dynamic character, an extraordinary phenomena shows that temperature decreasing occurs when the cast iron is stretched.

关 键 词：铸铁形变 温度改变 物理机理
