Hot rolling laboratory experiments were performed on an Al–Mn alloy, utilizing a rolling tribo‐simulator to characterize the evolution of near‐surface defects induced by tribological interactions between the work roll and alloy surfaces. A ten pass hot rolling schedule was conducted on Al–Mn samples using an AISI 52100 work roll polished to a surface roughness (Ra) of 0.01 μm. Micro‐cracks formed...
The effect of the work roll topography on the surface deformation of aluminum alloys during hot rolling was examined with the use of a rolling tribo‐simulator. AISI 52100 steel work rolls with two surface conditions, smooth (polished to a surface roughness (Ra) of 0.01 µm) and rough (WC‐coated with a surface roughness (Ra) of 5.68 µm), were used to hot roll Al‐Mg alloy samples under similar conditions...
