Effect of tempering temperature on the toughness of 9Cr–3W–3Co martensitic heat resistant steel
TL;DR: In this paper, the effect of tempering temperature on the toughness of 9Cr-3W-3Co martensitic heat resistant steel was studied on the basis of the microstructures after normalized at 1100 ǫ c for 1h and then tempered at 740-780 c for 3h.

Effect of microstructural evolution on high-temperature strength of 9Cr–3W–3Co martensitic heat resistant steel under different aging conditions
TL;DR: In this article, the evolution of microstructures and high-temperature strength of 9Cr-3W-3Co martensitic heat resistant steel after aging at 650°C and 700°C for different time durations have been experimentally investigated using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), field emission transmission electron microscope (FETEM), and post-aged tensile tests.

Effect of normalizing temperature on the strength of 9Cr–3W–3Co martensitic heat resistant steel
TL;DR: In this article, the authors investigated the structural and room temperature strength of 9Cr-3W-3Co martensitic heat resistant steel after normalizing at 900-1200°C for 1 1/h and then tempering at 750-1/h for 1/4h.

Carbide precipitation in austenite of a Ti–Mo-containing low-carbon steel during stress relaxation
TL;DR: In this paper, the carbide precipitation behavior in austenite of a 0.04%C−0.21%Mo micro-alloyed steel was investigated by the stress relaxation method and transmission electron microscopy.

Microstructure evolution of a hypereutectoid pearlite steel under rolling-sliding contact loading
TL;DR: In this paper, the microstructure evolution on the rolling surface of GCr15 steel subjected to rolling-sliding and pure rolling contact loading was systematically investigated, and it was found that the pearlite structure of the surface layer in the rollingsliding sample transformed into nanocrystalline α-Fe-C alloy in which cementite underwent severe decomposition while the pearllite lamellae appeared unperturbed in the pure rolling sample.
