测量了高碳钢和低碳钢在拉伸应变过程中的中子衍射谱，以比较有无增强相时铁素体钢的内应力演化。在低碳钢中，晶间应力的产生占主导地位，而在高碳钢中，铁素体晶系之间类似的晶间应力叠加在相间大量的应力重新分布上。并与弹塑性自洽方法和有限元方法进行了比较。
Neutron diffraction spectra have been acquired during tensile straining of high and low carbon steels, in order to compare the evolution of internal stress in ferritic steel with and without a reinforcing phase. In low carbon steel, the generation of intergranular stresses predominates, while in high carbon steel similar intergranular stresses among ferrite grain families are superposed upon a large redistribution of stress between phases. Comparison is made to calculations using elastoplastic self-consistent and finite element methods.
