In this study, we obtained different morphology and size of epsilon carbides (ϵ-carbides) via low temperature tempering 0.32 wt-% C alloy wear resistance steel. The objective is to elucidate the determining role on mechanical properties three-body impact resistance. formation small needle-like ϵ-carbides was responsible for increase in yield strength, toughness However, when were large rod-like, hardness, significantly reduced. mechanism steel containing primarily involved plastic...
Keeping through‐thickness homogeneity of mechanical properties has been a great challenge for producing heavy gauge steel plates. Herein, superior microstructure and hence strength toughness achieved in quenched tempered (QT) 210 mm‐thickness plate produced by advanced electroslag remelting casting roller quenching (ESR–RQ) technologies are reported. Some comparisons made with QT 178 mm conventional mold immersion the water tank (MC‐IQ). The martensite as‐quenched ESR–RQ is distributed...
Large-section ultra-heavy steel plates feature low cooling rate of central part during quenching process, as well great differences in texture and performance along thickness direction. Wet jet impingement test apparatus multi-channel temperature recorder were developed to explore the drop characteristics its influential factors plate. The curves with different (160, 220, 300 mm) weight (23-43 tons) recorded accompanied exploration on distribution rules gradient, heat flux density direction...
The cover shows the world’s first set roller quenching equipment for ultraheavy plates up to 300 mm thickness developed independently by Northeastern University in China. advanced electroslag remelting casting and processes make it possible produce extra heavy steel with excellent comprehensive performance.
