Sliding-induced stress gradients promote mechanochemical delamination, transforming bulk MAX phases into 2D layered structures.

The results indicated that while the addition of RE did not increase the depth of the carbonitrided layer, it did lead to an increase in both the size and content of carbides on the surface of the carbonitrided layer, thereby significantly improving its wear resistance. The underlying mechanism is as follows: RE compounds increase carburizing efficiency, which in turn increases the surface carbon concentration. Moreover, solid-solution RE atoms delay carbon diffusion into the center of the carbonitrided layer. Consequently, the carbon content is enriched on the surface of the carbonitrided layer, resulting in an increase in carbide size and quantity.

The resulting non-linear coupling between the normal and lateral directions is also investigated by measuring the changes in the indentation depth (conv. normal load) during the stiction of the adhesive contacts under imposed normal load (conv. indentation depth) conditions, with strong effects of contact confinement. From a comparison with adhesiveless linear contact mechanics calculations, we show that the experimental observations can only be accounted for by the occurrence of finite strains/displacements conditions.

Tempering was carried out at 300 ºC for 3 h and cooled under two different conditions, viz., in ambient conditions and the furnace environment individually. The processed Incoloy 925 samples were characterized using X-ray diffraction analysis (XRD). Energy dispersive X-ray Spectroscopic analysis (EDAX) and Scanning Electron Microscopic analysis (SEM) for microstructural changes. The Specimens were then subjected to microhardness measurements and wire electrical discharge machining (WEDM) to assess the effect of cryogenic treatment and tempering on the material's machinability using material removal rate, surface roughness, and kerf width. The process parameters of WEDM were optimized using Entropy-EDAS methods. It was understood from the results that the cryo-treated and tempered Incoloy 925 exhibited refined crystal size and surface morphology. The cryo-treated and tempered Incoloy 925 with furnace cooling exhibited a high microhardness value and machinability owing to more refinement in microstructure during the treatment and tempering process. From the optimization results, a minimum surface roughness, maximum materials removal rate and kerf width were obtained for a pulse on time of 25 µs, a pulse off time of 48 µs and an input current of 4 A.
