Special Issue Information

Dear Colleagues,

Aluminum alloys, titanium alloys, magnesium alloys, and nickel super alloys are some of the most widely used alloys in such strategic industrial sectors as the aeronautic, automotive, and biomechanical industries, both individually and hybridized with composite materials. Their excellent mechanical and physical-chemical properties, such as their high strength-to-weight ratio, corrosion resistance, high stiffness, good fracture toughness, and fatigue behavior make these light alloys an excellent alternative to other materials in engineering applications. However, many of these materials have problems in their ability to be manufactured, especially when sustainable manufacturing processes are applied, due to certain social, economic, and environmental issues.  

The goal of this Special Issue is to provide a comprehensive overview of the more recent advances in the field of sustainable manufacturing of light alloys, which include machining, forming and additive novel processing techniques, sustainable manufacturing technologies, eco-friendly lubrication and cooling systems, and advanced simulation methods.  

Examples of innovative and successful industrial applications, especially in the aeronautical, aerospace, automotive, biomechanical and biomedical sectors, as well as non-conventional experimental or numerical approaches and simulations, are also encouraged. 

Research and review papers addressing all aspects of the sustainable manufacturing of light alloys are welcome.

Applicability of the Electrochemical Oxygen Sensor for In-Situ Evaluation of MgO Solubility in the MgF2–LiF Molten Salt Electrolysis System

The measurement and evaluation of MgO solubility in the molten fluoride system is of significant importance in the recently proposed magnesium electrolysis reduction process. In the present study, an in-situ quantitative method of evaluating the concentration of dissolved MgO in molten fluoride is proposed. The MgO solubility in the 32.8MgF2–67.2LiF system was measured at 1083 and 1123 K using a combustion analyzer. MgO saturation was achieved in under 2 h, and higher solubilities were observed as the temperature increased. Thermodynamic assessment was carried out in order to ascertain the applicability of the electrochemical oxygen sensor, which indicated that the logarithm of oxygen concentration in molten fluoride has a linear relationship with the measured electromotive force (EMF) potential. The EMF potential of the controlled MgO concentration was measured, and a straight calibration line was obtained, describing the relationship between the measured EMF and the logarithm of MgO concentration. From the obtained calibration line, MgO concentration in the 0.4 wt% MgO was calculated. The calculated value was 0.44 wt% that was in excellent accordance with the controlled MgO concentration of 0.4 wt%, verifying the practical applicability of electrochemical oxygen for the in-situ monitoring and evaluation of MgO solubility in the electrolysis magnesium reduction process.

Fatigue behavior takes special relevance in structural parts for aircraft due to safety reasons. Despite its environmental advantages, dry machining of these parts may negatively affect their surface integrity, which may lead to a reduction in fatigue life. Nevertheless, there is a lack of research focused on the analysis of the cutting parameters influence on fatigue behavior in dry machining of aeronautical aluminum alloys, in spite of its importance. Therefore, in this work, an analysis of the cutting speed and feed influence on fatigue behavior of dry turned UNS A97075-T6 alloy is presented. The stress-fatigue life curves have been obtained and corrected according to the applied cutting parameters values. Additionally, the surface roughness and two macro-geometrical deviations (cylindricity and concentricity) have been controlled. The experimental results have revealed that fatigue life is reduced when high values of cutting speed and feed are combined. Finally, a parametric potential equation for fatigue life, as a function of the load and the cutting parameters, has been developed. The relation has been obtained for the theoretical fracture section and, as the main novelty, corrected for the real one. Full article
