“…Strikes, which can also be described as micro-cold forging, cause severe plastic and elastic deformation at the near surface layer, thus creating a nanocrystalline structure with a compression residual stress of around 10 μm in depth [55]. Strikes also create controllable micro-narrows at the surface of the sample, which improves the tribological characteristics of the interlocking surfaces in relative motion [56]. Each of the micro-dimples produced by laser surface texturing can function as a micro-hydrodynamic bearing that mitigates the detrimental effects of poor lubrication in sliding or rolling contact conditions, thereby enhancing the performance and durability of the lubricated system [57].…”

Metastable austenitic stainless steels (MASS) are widely used in various industrial applications due to their exceptional compromise between mechanical properties and corrosion resistance. However, the mechanical properties of these materials can be further enhanced by surface treatments. This paper reviews various surface treatment methodologies used to improve the mechanical properties of MASS, with particular attention to laser treatments. The effects of these surface treatments on the microstructure and chemical composition in the thermal affected zone of the MASS are discussed, and their impact on the material’s mechanical properties, such as hardness, tensile strength, and fatigue life, are investigated in detail. Additionally, the paper highlights the limitations of these surface treatments and points out some areas where further research is needed. The findings presented can be used to guide the selection of appropriate surface treatment techniques for specific applications, ultimately improving the performance and lifespan of MASS in various industrial settings.

“…Among various titanium-based alloys, Ti-6Al-4V alloy is considered one of the most common biocompatible alloys due to its lower elastic modulus than stainless steel and cobalt–chromium alloys [ 4 , 5 , 6 ]. However, the presence of toxic elements such as aluminum and vanadium in the human body can lead to various health issues over time [ 7 , 8 , 9 , 10 , 11 ].…”

The use of titanium and titanium-based alloys in the human body due to their resistance to corrosion, implant ology and dentistry has led to significant progress in promoting new technologies. Regarding their excellent mechanical, physical and biological performance, new titanium alloys with non-toxic elements and long-term performance in the human body are described today. The main compositions of Ti-based alloys and properties comparable to existing classical alloys (C.P. TI, Ti-6Al-4V, Co-Cr-Mo, etc.) are used for medical applications. The addition of non-toxic elements such as Mo, Cu, Si, Zr and Mn also provides benefits, such as reducing the modulus of elasticity, increasing corrosion resistance and improving biocompatibility. In the present study, when choosing Ti-9Mo alloy, aluminum and copper (Cu) elements were added to it. These two alloys were chosen because one element is considered a favorable element for the body (copper) and the other element is harmful to the body (aluminum). By adding the copper alloy element to the Ti-9Mo alloy, the elastic modulus decreases to a minimum value of 97 GPa, and the aluminum alloy element increases the elastic modulus up to 118 GPa. Due to their similar properties, Ti-Mo-Cu alloys are found to be a good optional alloy to use.

“…Today, there is an increasing demand for ultra-precision finishing due to the complex geometries of workpieces in advanced industries and the significant effects of surface roughness on the function and durability of workpieces [1,2]. Traditional finishing methods, such as grinding and honing, not only have low efficiency in the ultra-precision finishing of complex shapes but also cause surface and subsurface damage to the workpiece.…”
