“…σY, σ o , k y , and d are the yield strength, a materials constant for the starting stress for dislocation movement, strengthening coefficient, and average grain size, respectively. Many of the previous researches also confirm the validity of Hall–Petch equation for the metals and alloys processed by SPD methods with ultrafine grains ranging from 1 µm to 100 nm [39,40,41,42,43,44].…”

In current research, the effect of the multi-directional forging (MDF) process on the microstructure, texture, mechanical and electrical properties of AA-6063 under different heat treatment conditions at various MDF temperatures was studied. The annealed AA-6063 alloy was processed up to three passes of MDF at ambient temperature. Three passes of this process were also applied to the solution-treated AA-6063 at ambient temperature and 177 °C. Microstructural investigations demonstrated that the MDF process led to a significant reduction in the average grain size as well as a considerable increase in the fraction of low angle grain boundaries. Texture analysis revealed that copper and Goss textures were mainly developed within the annealed and solution-treated samples of AA-6063, respectively. The hardness and shear strength values of all processed samples also showed a sizeable improvement compared to the initial heat-treated samples. For example, the hardness and shear yield strength value of the solution-treated sample MDFed for three passes showed more than 100 and 70% increase, respectively. The effect of the MDF process on the electrical conductivity of AA-6063 under different heat treatment conditions at various temperatures was negligible. So, it can be concluded that the MDF process increased the mechanical properties without an appreciable decrease in electrical conductivity.

“…The ranking of the hardness and the wear resistance was SHT alloy > FC alloy > AC alloy > HO alloy. The relationship between the hardness and the wear resistance could be explained by Archard's equation: (15) W Resistance = KH/N. K is the wear coefficient, H is the hardness, and N is the applied load during sliding.…”

The developments of biodegradable materials for orthopaedic implants has been progressing rapidly for decades. Biodegradable implants can eliminate the need for a second surgery and avoid the possible risks of retained metallic implants, such as corrosion or strength weakening. Magnesium (Mg) alloy is one of the potential materials for biodegradable implants because of its good biocompatibility and biodegradability. In this study, the microstructures and mechanical properties, especially the wear behavior and friction characteristics of Mg-Sn alloys, were investigated. Mg-Sn alloys fabricated by the ingot casting method were applied to different heat treatments, and then subjected to the pin-on-disc wear test. Experimental results showed that the Mg-Sn alloy processed by solution heat treatment (SHT) at 520 ℃ and quenching had the best wear resistance and lowest coefficient of friction (COF). The decrease in the amount of hard precipitate Mg 2 Sn and the solid-solution strengthening induced by the excess Sn atoms in the Mg matrix were the main causes of the enhancement of the wear properties of the Mg-Sn alloy upon SHT, compared with as-cast Mg-Sn alloy and the Mg-Sn alloys made by other heat treatments.

“…resistance than pure magnesium (Mg) and possess excellent mechanical properties and creepresistance at high temperatures due to the presence of the Mg2Sn phase. The melting point of this intermetallic phase in Mg-Sn alloys (770°C) is much higher than that of the Mg17Al12 phase in Mg-Al alloys (462°C) [11][12][13].…”

The present study investigated the effects of alloying and nano-reinforcement on the mechanical properties (microhardness, tensile strength, and compressive strength) of Mg-based alloys and composites. Pure Mg, Mg-3Sn alloy, and Mg-3Sn+0.2GNP alloy-nanocomposite were synthesized by powder metallurgy followed by hot extrusion. The microstructural characteristics of the bulk extruded samples were explored using X-ray diffraction, field-emission scanning electron microscopy, and optical microscopy and their mechanical properties were compared. The microhardness, tensile strength, and compressive strength of the Mg-3Sn alloy improved when compared to those of monolithic Mg sample and further improvements were displayed by Mg-3Sn+0.2GNP alloy-nanocomposite. No significant change in the compressive strain to failure was observed in both the alloy and the alloy-nanocomposite with respect to that of the pure Mg sample. However, an enhanced tensile strain to failure was displayed by both the alloy and the alloy-nanocomposite.
