Summary: In this research, cryogenic friction stir welding (CFSW) using liquid nitrogen as a medium was performed to join two similar ZE42 magnesium alloy plates. The effects of welding parameters on welding characteristics were investigated, and the predicted optimum welding settings were utilized to compare the CFSW and NFSW performances. The results showed that CFSW improved tensile strength and hardness by 41.36% and 35.13% respectively, and reduced the wear rate by 23.53% compared to NFSW.

Summary: This study fabricates a superhard titanium boride coating on titanium surface using high power diode laser alloying. Amorphous boron is transformed into crystalline boron by high-power laser interaction and rapidly combines with titanium to form titanium boride precipitates. The laser borided coating exhibits dendrites and whisker-like microstructures, with microhardness ranging from 800-1600 HV0.2 and extreme hardness of 3800-4700 HV0.2 in some regions of boron precipitates. The formation of TiB and TiB2 phases shows a high negative Gibbs free energy and an activation energy of 140 kJ/mol, indicating the spontaneity of the reaction. The laser borided coating with TiB and TiB2 phases has potential for surface engineering applications.

Summary: In this study, Al7075+0%Ti-, Al7075+2%Ti-, Al7075+4%Ti-, and Al7075+8%Ti-reinforced alloys were prepared and examined for their microstructure, mechanical behavior, and dry-wear behavior. The addition of Ti increased the peak hardness and wear resistance of the Al7075 alloy, attributed to the formation of oxide films, precipitation hardening, secondary hardening, grain refinement, and solid-solution-hardening mechanisms.

The specimens were characterized by various methods and the results showed that increasing SiC content to 10 wt% improved the hardness and wear resistance of the nanocomposite samples. The dominant wear mechanism was found to be abrasive wear accompanied by oxidation wear. Additionally, the hybrid composite sample containing 7.5 wt% nano SiC exhibited the highest tensile strength compared to other hybrid composites.

Summary: Nd: YAG laser beam welding was used to join grade 2 titanium tubes. The effect of laser power was studied through metallurgical characterization and mechanical tests. It was found that as power increased, the bead geometry changed from wedge to parallel. The weld zone exhibited a rough, uneven, and serrated coarse granular texture. Laser power had a significant impact on the misorientation angle patterns, with higher power resulting in larger pores. The weld zone showed high density dislocation patterns and more sub grain boundaries. Laser welding strengthened the weld zone, with less strengthening observed at higher laser power in microhardness analysis. Lower laser power achieved higher tensile strength. Ductile failure was observed due to fine voids in the fracture surface analysis.

Summary: The microstructural, mechanical, and wear properties of Al-4.28 Cu-1.60 Mg alloy micro-alloyed with titanium (Ti) at different concentrations (0.02, 0.04, and 0.08 wt.%) were investigated. SEM and EDS analyses revealed the presence of two major phases, CuAl2 and Fe-rich (Al-Cu-Mg-Si-Fe-Mn) phase, in the as-cast base alloys. Addition of Ti resulted in increased hardness and tensile strength after aging. The improvement in tensile strength and elongation was higher for rolled alloys compared to cast alloys under peak aged condition, especially for 0.08 wt.% Ti. Wear study showed that Ti addition decreased the wear rate.

Summary: By adding Ti5Si3 to the titanium alloy and performing solution aging treatment, an ultrahard alloy was obtained. However, the wear resistance of the alloy is poor due to the increase in frictional forces caused by the reduction in Ti5Si3 and the generation of wear debris that leads to oxidative and adhesive wear.

Summary: This study aims to improve the microhardness and wear properties of as-cast titanium samples (CP-Ti, Ti-Al-4V, and TNZ-33) by creating a hard surface through plasma nitriding. The presence of nitrides was evaluated using XRD, and the microstructure and chemical composition were analyzed using electron microscopy and EDS. Plasma nitriding resulted in the formation of TiN on CP-Ti, TiN and Ti2N on Ti-6Al-4V, and TiN and ZrN on TNZ-33. The hardness of all materials significantly increased after nitriding, and the wear properties were improved.

Summary: In this study, WC-10Co-4Cr coating was deposited on textured and non-textured 420 martensitic stainless steel, and laser surface texturing (LST) was conducted to improve mechanical interlocking and hardness at the coating-substrate interface. The results showed that the lattice strain was highest on the textured surface due to surface dislocations caused by laser ablation, while the coated surface had less strain due to regularly ordered roughness. The LST also effectively increased the surface hardness of the coated specimens.
