In the presented work on the basis of extrema on curves: efforts of resistance of draft, parameters of thin structure, metalgraphic structure depending on temperature and also numerous literary data on anomalies of physicomechanical properties of iron and staly transformation is declared at ~ 650 C. The research was conducted on samples from almost pure iron (0,008% C). An experiment (the metalgraphic research, the X-ray diffraction analysis, resistance to draft (Gleeble-3800) carried out through each 20 C.
