摘要：

Cyclic strain hardening has been observed to be markedly sensitive to microstructural changes in microalloyed steels. Two significantly different microstructures, polygonal ferrite grains of average grain size 10-120 mu m and acicular ferrite/upper bainite colonies of dimensions 200-625 mu m, were examined in order to determine the influence of each on cyclic strain hardening and related properties. Tests were conducted at temperatures between minus 150 and 27 degree C.
