the effect of subsurface deformation on the wear behavior

Effect of Hot Deformation and Aging of AA7075-Based 10 wt

Jun 05, 2020 · The graphite-reinforced Al-based composite finds application in improving wear behavior. The present work investigates the effect of secondary processing such as hot forging and heat treatment on monolithic alloy and 10 wt.% graphite-reinforced AA7075 composite fabricated by liquid metallurgy route. Melting was carried out in an induction furnace and cast in a steel mold having dimension 45 Effect of Hot Deformation on the Wear Behavior of Al O Pin on disc wear test was used to study wear behavior of prepared Al2O3/A356 nano composites while scanning electron microscopy used to build up the wear mechanism. The results showed that the hot deformed nano Al2O3 /A356 composites have lower wear rate compared with non deformed one.

Effect of Layer Thickness on the Rolling-Sliding Wear

Jul 01, 2002 · However, subsurface plastic deformation occurs beneath the layer, leading to the catastrophic failure of the layer and a transition in the wear rate after a limited duration of testing. The thickest layer tested produces the best wear performance under the present rolling-sliding test conditions. Effect of Microstructural Evolution and Hardening in Aug 28, 2013 · The results illustrate the correlation between the wear behavior and evolution of microstructure and hardness in subsurface, and reveal that in the load range of 5-120 N, surface oxidation and hardening originating from large plastic deformation play an important role in maintaining the mild wear, and softening originating from dynamic recrystallization in subsurface and surface Effect of Tool Wear on Subsurface Deformation of Nickel Fig. 2(a), (b) and (c) demonstrate the effect of tool wear on the deformation of subsurface layer when tool changes from new, semi-worn and worn tool. The deformations and slip in grain boundaries and elongation of grains indicate the severe plastic deformation in the subsurface layer. When cutting with a

Subsurface Dynamic Deformation and Nano-structural Aug 20, 2019 · Pronounced vortex structures are generated in the localized subsurface zones due to high strain localization and shear instability. With the prolongation of sliding distances, vortex structures suffer dynamic embrittlement and exfoliation from the wear surface as a result of periodically excessive hardening effect, leading to the high wear rate in stable wear stage.

Worn surface and subsurface layer structure formation

While wear rate significantly decreased with increasing sliding time due to oxidation of wear debris on worn surface and formation of deformed layer with grain refinement resists the plastic deformation by strengthening the subsurface layers.The effects of subsurface deformation on the sliding wear Aug 01, 2004 · It was shown that deformation induces a martensitic phase transformation below the wear track. This was not expected, since a high amount of interstitially solved nitrogen generally stabilizes the austenite lattice and thereby inhibits any thermally induced martensite formation, even at cryogenic temperatures [19] .
