“…Likewise, heat treatment was reportedly carried out after hot extrusion in solid-state recycling. 51 The extruded rod was solution-treated at a temperature of 415°C for 24 h in an argon atmosphere followed by oil quenching, and finally aged at temperatures of 170°C and 215°C to improve the mechanical properties. Other than that, direct recycling can also be done by other means as described below.…”

This article provides an intensive review of the past and current research work on the solid-state recycling of light metals. The review includes an experimental aspect of the relevant works that clearly clarify the effects of several critical factors noted as chip preparation, reinforcing phases, die geometry, process parameter selection and performance of miscellaneous methods over the quality of the extruded profiles. Likewise, reviews of numerical and analytical works on the solid-state recycling were presented to understand the strengthening phenomena of chip-based billet through the plastic deformation. Finally, concluding remarks underline challenges of direct recycling method and subsequently highlight the potential future work on making the method as a promising alternative for sustainable manufacturing agenda.

“…For further improved mechanical properties, the semisolid extrusion process was developed, whereby the pre-compacted chips are heated to a specified semisolid temperature before the final extrusion [62,63]. It was studied that the mechanical properties can also be improved by suitable heat treatments [64]. However, solid-state recycling has not been widely used due to potential problems such as the dispersion of the second phase and the formation of the micro-voids [15].…”

Aluminium alloys are promising materials in EVs due to their advantages such as high specific strength, corrosion resistance and recyclability. However, forming complex-shaped thin-wall aluminium products is challenging due to their poor formability and limited dimensional accuracy. Meanwhile, recycling some of the high-strength aluminium alloys from EVs is still challenging. This review highlights some of the future potential aluminium forming techniques for EV production, including incremental sheet forming (ISF), hot forming and quenching (HFQ ® ) technique, and transverse stretching and local bending (TSLB). Also, the issues associated with aluminium recycling are listed and discussed. This review provides scientific guidance to the industry and the scientific community for advancing the applications of aluminium alloys in EVs.

“…Although light metals such as aluminum or magnesium are easier to machine, the magnesium alloys have a higher specific strength and stiffness than aluminum alloys. [1][2][3] Metallic implants made of stainless steel, titanium or cobalt-chromium alloys are used for stress shielding and revision surgeries, improving the quality of life and the healthcare system. On the other hand, due to their low density and compatibility, magnesium alloys are also very promising as orthopedic biomaterials compared to the other metallic alloys such as stainless steel and titanium alloys.…”

Mg alloy MA8M is used in the aerospace and food industries and in biomedical applications due to its lightness and biocompatibility. This paper presents the drilling performance of the standard HSS and TiBN-coated drill bits during the machining of the MA8M Mg alloy at various drill rotational speeds and feed rates. After the experiments, the surface roughness, topography and chip formation were analyzed. Atomic-force microscopy (AFM) and surface profilometer were used for this purpose. It was observed that higher drilling feed rates and drill rotational speeds lead to lower surface-roughness values. TiBN-coated drill bits exhibited undesired surface qualities. Keywords: MA8M Mg alloy, TiBN coating, twist drills, surface quality, multiple regression analysis, chip formation Mg zlitina MA8M se uporablja v letalstvu, prehrambeni industriji in v biomedicini, ker je lahka in biokompatibilna.^lanek predstavlja obna{anje pri vrtanju z normalnimi HSS in s svedri s TiBN prevleko na konici, pri obdelavi Mg zlitine MA8M pri razli~nih vrtljajih svedra in hitrostih podajanja. Po eksperimentih je bila analizirana hrapavost povr{ine, topografija in nastanek ostru`ka. V ta namen sta bila uporabljena mikroskop na atomsko silo (AFM) in profilometer povr{ine. Ugotovljeno je, da ve~ja hitrost podajanja in vrtenja svedra povzro~i manj{o hrapavost povr{ine. S TiBN prevle~eni svedri so povzro~ali neustrezno kvaliteto povr{ine. Klju~ne besede: MA8M Mg zlitina, TiBN prevleka, vija~ni svedri, kvaliteta povr{ine, multipla regresijska analiza, nastanek ostru`ka
