Method of production of products is very high load at failure on the basis of a steel austhenitique are unstable, and in the resultant.

摘要

According to this process is subjected to the steel to a first plastic deformation at a temperature higher than the limit temperature (md) of the formation of the martensite of deformation and below the recrystallization temperature, then to a second deformation at a temperature lower than the said temperature (md). During the second deformation, it deforms the steel in a determined temperature of formation of the martensite of deformation so as to a rational of 0,1, the increase in the amount of martensite formed does not exceed, at any instant, 20%.
