Mean flow stress of HSLA steel of type Ni-Cu-Cr-Mo-Nb

Popis výsledku v původním jazyce

In laboratory conditions the heat of the HSLA steel of the type Ni-Cu-Cr-Mo-Nb, which should comply with requirements of the standard API-X100, was manufactured. Rolling temperatures ranged from 750 to 1150°C, effective height reduction to the value of 0.45 and strain rate from 8 to 88 s-1. The obtained values of mean flow stress were used for set-up of the model of deformation resistance. It is difficult to describe the temperature dependence of mean flow stress by a simple equation in the whole rangeof experimental temperatures, even though its accuracy is from purely statistical point of view satisfactory. That is why two additional models of mean flow stress of the investigated steel were also developed, namely for temperatures below 950°C and above this value. The deformation resistance characteristics of the given steel and the HSLA steel of the type Mn-Ni-Nb-Ti, investigated before, were compared as well.
