Abstract Railway wheels are commonly made from medium carbon steels (~0.55 wt.% C), heat treated to a near pearlitic microstructure with 5–10% pro-eutectoid ferrite. During the operation of freight trains, where block brakes used, high thermal loads occur together contact stresses, which combined can affect mechanical properties material. In this study, effects annealing on local and in railway...

Molten LiCl-KCl salt and liquid cadmium are proposed as the electrolyte reactive cathode for electrorefining of spent nuclear fuels, but they can be corrosive to structural alloys. The down-selection existing materials through corrosion testing is necessary ensure longevity electrorefiner vessel electrode assemblies. Haynes C276, Inconel 600, AISI 316L stainless steel, 42CrMo low-alloy steel we...

In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...

A model that describes pearlite-to-austenite transformation during continuous heating in a eutectoid steel has been developed. The influence of structure parameters, such as interlamellar spacing and edge length of pearlite colonies, and heating rate on the austenite formation kinetics has been experimentally studied and considered in the modeling. It has been found that the kinetics of austeni...

Critical aspects of innovative design in engineering disciplines like infrastructure, transportation, and medical applications require the joining dissimilar materials. This study investigates literature on solid-state bonding techniques, with a particular focus diffusion bonding, as an effective method for establishing bonds. Welding brazing, while widely used, may pose challenges when materia...

Laser fusion chamber walls will experience large, pulsed heat loads at frequencies of several hertz. The heating, consisting of x-rays, neutrons, and ions, occurs over a few microseconds and is deposited volumetrically over the first few microns of the wall. For a reasonable chamber radius, the heating will be such that the surface temperature is a significant fraction of the melt temperature o...
