Wear behavior and the corresponding work hardening characteristics of Hadfield steel
TL;DR: In this article, the wear properties of N+Cr alloyed Hadfield steel and traditional hadfield steel (i.e., Mn12CrN steel) were studied and the effect of N and Cr combination alloying on initial strength and twinning behavior was investigated.

Effects of austempering temperature on bainitic microstructure and mechanical properties of a high-C high-Si steel
TL;DR: In this paper, a high-C high-Si bainitic steel, by austempering around the nose-tip temperature of the TTTT diagram, revealed multiple lengths of nanobainite plates and various sizes and shapes of retained austenite.

Effect of N+Cr alloying on the microstructures and tensile properties of Hadfield steel
TL;DR: The microstructures and tensile behaviors of traditional Hadfield steel, named Mn12 steel, and hadfield steel alloyed with N+Cr, called Mn12CrN steel, were studied through optical microscopy, transmission electron microscopy and scanning electron microscope, among others.

Strain hardening and nanocrystallization behaviors in Hadfield steel subjected to surface severe plastic deformation
TL;DR: In this paper, a gradient nanocrystalline layer with a thickness in a range of millimeter magnitude was successfully produced on the surface of Hadfield steel by a novel severe plastic deformation technology, high speed pounding.

Low-cycle fatigue behaviors of pre-hardening Hadfield steel
TL;DR: In this article, the effect of pre-hardening on low-cycle fatigue behavior of the Hadfield steel was analyzed through comparing the cyclic hardening/softening behaviors and the changing regulations of stress amplitude, internal stress, and effective stress at different total strain amplitudes.
