Effect of Vanadium Addition on the Surface Roughness and Fatigue Crack Propagation in a Railroad Wheel Using Twin Disc Wear Test

Autor: S.T. Fonseca, Paulo Roberto Mei, Domingos José Minicucci, G.A. Amorim, A.B. Rezende

Publikováno v: Defect and Diffusion Forum. 391:66-73

To verify the effect of 0.13 % vanadium addition (% in weight) on the wear resistance of a railroad wheel steel with 0.7 % carbon, twin-disc rolling-sliding test were performed. These two steels were named 7V and 7C. The test discs were analyzed to v

Going Beyond Conventional Problem Solving for Two Railroad Wheel Defects

Autor: S. Dedmon

Publikováno v: 2019 Joint Rail Conference.

Conventional problem solving is a time-honored and accepted methodology for solving many problems we encounter in our daily home and work lives. Thought processes can be linear (like a programmer) or non-linear and still use conventional problem solv
