“…Also, the roughness should vary within a narrow range for the entire surface. Roll surface roughness is vital in imparting these properties to a sheet surface (Çolak, 2021;Çolak & Kurgan, 2018). No matter how homogeneous the roll surface roughness is, it may not be sufficient to get a homogeneous roughness distribution on the material surface.…”

This study investigated the effect of rolling parameters such as speed, thickness reduction, roll surface roughness, material thickness, surface condition (dry or lubricated), and rolling force on the roughening characterization in asymmetrical rolling. The surface roughness of the samples subjected to rolling tests was measured. The roughness values' average and standard deviation were found, and 3-D scanning images were acquired. Lubricated texturing experiments revealed that lubrication reduced roughness transfer. It was found that the introduction of roughness on the material surface decreased as the rolling speed increased. On the other hand, a higher speed increases the rolling force, which increases the surface roughness. The effect of speed on the standard deviation varies in direct proportion. Furthermore, lubricated rolling produced a more homogenous roughness distribution at higher speeds, while dry rolling produced homogeneous roughness at lower speeds. It was revealed that the rolling force is higher with thicker materials. While the roll roughness did not affect the rolling force using thicker material much, this effect was more pronounced in the very rough roll using thinner material. The standard deviation was lower in smaller reduction ratios using rough and very rough rolls. According to the results, although asymmetrical rolling has some advantages compared to conventional rolling, it was concluded that it is not a suitable method for roughening steel strips.

“…Aluminum alloys have excellent strength-to-weight ratios and high corrosion resistance. Therefore, they are widely used for automotive, aerospace, construction industries, and marine applications [1][2][3]. Aluminum 7075 alloy is age-hardened among all other aluminum alloys; hence, comparatively, it possesses higher strength [4,5].…”

Laser shock peening is a well-known surface treatment process that dominates other modern surface treatment processes. Though several materials are investigated toenhance mechanical properties by LSP treatment, only a scarce number of studies have concentrated on Low Pulsed Laser Shock Peening (LPLSP) without an ablative layeron Aluminum Alloy 7075 T651 material. Thus this article investigates the optimization and effect of LPLSP on the mechanical behavior of AA 7075 T651. Grey Relational Analysis is chosen to optimize the Process Parameters on Low Pulsed Energy of LSP. The significant contributions of the optimized parameters on the mechanical behavior such as hardness, compressive residual stress, roughness and friction wear property are investigated. A drastic improvementof three times in the average hardness value occurred in LPLSP over the un-peened specimen. A maximum compressive residual stress is observed with the LPLSP specimen for the optimized parameters. An improvement of 65 % in the minimum wear rate was recorded in LPLSP compared to unpeened specimens. The microstructural studies carried outusing an optical microscope and scanning electron microscope show a typical grain refinement and increase in the boundary for LPLSP specimen.

Surface Topography: Metrology and Properties (STMP) is reaching its 10th Birthday soon and this paper looks at the inception of the journal and the goals set in the mid 2010s and will look back at what it has published in the most highly cited areas and detail future initiatives to serve the readership. STMP publishes the latest physics, chemistry, life science, materials science and engineering research on applied, functional surfaces. It has published ground-breaking work on surface design, measurement, instrumentation, manufacturing, functionality and modelling as well as cross-disciplinary work on surface and interface engineering across an array of different applications. It is the home of papers from the biannual international conference on Metrology and Properties of Surfaces series. The journal was awarded it’s first impact factor in 2017 and has a current value of 2.038 (2020) and is now working to improve on this. A new initiative for 2021 is to offer a collection of papers from emerging leaders within the scope of the journal.
