In this study, quenching and tempering were employed to achieve the optimal match of strength toughness high-strength low-alloy (HSLA) 15CrNi3MoV steel. The effect temperature on microstructure evolution carbides precipitation steel was also investigated using scanning electron microscopy (SEM), a X-ray diffractometer (XRD) transmission (TEM). results showed that after at different temperatures...

thermomechanical control process steel produced by rolling has a significant anisotropy. the elongated grains and inclusions formed during hot rolling of ferrite and low carbon hsla steels directly influence the anisotropy of the steel’s mechanical properties as a result of microstructural anisotropy. the present research deals with this anisotropy, and particular attention has been paid to the...
