The relation between working temperature (T°K), degree of deformation. (γ%) and the lapse of time before recrystallizing (t sec.) was obtained as the curves, as shown in Fig. 1. Specimens were carbon steels, Cr steel, Cr-Mo steel and high speed steels. Considerations were given on these curves and the empirical formula was given. The results are as follows :
\ oindent(1) The relation between logt and 1⁄T, under γ=constant, came out nearly as a straight line for every steel. Activation energies were calculated from them.
\ oindent(2) It was ascertained that the relation between t and γ could be expressed by the following formula for every steel, \[lnt+Aγ1⁄n=B\] where, A and B depend on the material and the temperature, and n varies with the material but not remarkably with the temperature.
