Hot Forging Die Design Optimization Using FEM Analysis for Near-Net Forming of 18CrNiMo7-6 Steel Pinion Shaft

Metals, 2023
The objective of the presented work was to develop a new forging process for a pinion shaft as a component of a wind turbine. A study of near-net-shape forming using Deform 3D software was performed to reduce operational cost, time, and material scrap ...

Tailoring the Hardening Behavior of 18CrNiMo7-6 via Cu Alloying

, 2016
In order to improve the rolling contact fatigue (RCF) behavior of gear steels, a concept to increase their damage tolerance is developed alternatively to the conventional approach of improving the degree of steel cleanliness. For that purpose, Cu is used

Evolution of friction and wear in rack-railway gear–rack pairs under heavy-load dry sliding conditions

AIP Advances
Rack railways commonly operate under extreme conditions—steep gradients, heavy loads, and dry sliding—where wear of the gear–rack pair becomes a critical limitation to both safety and cost-effectiveness.

Effect of the Carburizing Process on the Microstructure and Properties of 18CrNiMo7-6 Steel

High-temperature carburizing heat treatment of 18CrNiMo7-6 steel was carried out at 930 °C, 950 °C and 970 °C. The effects of carburizing process on the microstructure, hardness and wear resistance of 18CrNiMo7-6 steel were studied. The results showed that the microstructure after high-temperature carburizing was mainly tempered martensite, and there ...
