The Effect of Cyclic Heat Treatment on the Microstructure and Mechanical Properties of 18CrNiMo7-6 Gear Steel [PDF]
MaterialsTo avoid grain coarsening resulting from high-temperature carburizing, the effects of cyclic quenching and tempering on the microstructure and mechanical properties of 18CrNiMo7-6 gear steel were investigated. Three groups of samples were compared, which went through 0/1/3 times of quenching–tempering cycles after initial pseudo-carburizing.

Simulation and Mechanical Properties of Fine-Grained Heat-Affected Zone Microstructure in 18CrNiMo7-6 Steel. [PDF]
Materials (Basel), 2022 Heat-affected zones (HAZs) in real welds are usually quite narrow, and consequently most standard mechanical tests are difficult or even impossible. Therefore, simulated microstructures are often used for mechanical tests. However, the most often used weld thermal cycle simulator produces only a few millimeters wide area of simulated microstructure in ...

Effect of temperature on the frictional behavior of 18CrNiMo7-6 under lubrication
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022 In the process of gear meshing, the tooth surface will produce friction heat, which will in turn act on the friction coefficient. The temperature does not directly affect the friction coefficient of the gear tooth surface, but indirectly through ...
