| Abstract: | The low-alloy and low cost wear-resistant HSLA NM400 steel plate with high toughness was developed by Ti-Cr-B micro alloying,then direct rolling at austenite recrystallization zone with low-temperature tempering after quenching.Its mechanical properties,microstructure,fracture morphology and precipitates were tested and investigated by means of optical microscope(OM),scanning electron microscope(SEM) and transmission electron microscope(TEM).The results showed that the microstructure of specimens is mainly ... |
