摘要：

X-ray and magnetometric methods are used to investigate the effect of multiple gamma double left right arrow alpha. transitions on the crystal structure and characteristics of the subsequent martensitic transformations in carbon iron-nickel alloys. It is shown that the effect depends on the heating rate in the range of the reverse alpha --> gamma transitions and is mainly governed by the thermal stability of the carbon gamma -solid solution in relation to decomposition with precipitation of carbon.
