This study presents an advanced approach utilizing vacuum distillation (VD) to purify Al from Al–Mg alloys. The activity coefficients of Al-Mg binary alloy components were meticulously determined by applying the molecular interaction volume model (MIVM), non-random two-liquid (NRTL) model, and Wilson equation. Comparative analysis between experimental data calculated enabled selection optimal exhibiting high computational accuracy extensive applicability. NRTL chosen for its precision, was then employed compute across various temperatures, leading development a vapor-liquid equilibrium (VLE) diagram. VLE diagram provides robust quantitative foundation assessing purification limits within temperature range 973–1373 K in process. Theoretical analyses underscore that VD offers rapid efficient method purification. Experimental verification at kilogram scale, conducted 1373 120 min, achieved purity level 99.9989% with direct recovery efficiency 97.98%. Notably, this process aligns environmental standards sustainable metallurgical practices, as it prevents release gaseous emissions or effluents, thereby meeting industry's growing demand eco-friendly recycling methods.

Wire arc additive manufacturing (WAAM) stands as an efficient and cost-effective method for producing large-scale engineering components while minimizing waste. This study explores the influence of WAAM process parameters on nickel aluminum bronze (NAB) parts, focusing wire feed rate (WFR) a key factor governing heat input its effects bead geometry, microstructure, mechanical properties. The investigation involved depositing single from NAB alloy varying WFS within 2–7 m/min range, resulting in inputs ranging 20.600 to 57.960 kJ/m. results revealed that increasing up 34.944 kJ/m led augmentation dimensions increased hardness due κ-precipitates formation α-Cu matrix. However, with further increments 49.088 kJ/m, exhibited decline uniformity intermetallic κ distribution lessened. Through optimization parameters, defect-free single-wall was successfully manufactured enhanced tensile strength along horizontal direction found be superior vertical direction, irrespective specimen's extraction regions. Additionally, bottom specimen slightly higher than center upper specimens being initial layers wall deposited substrate plate, undergoing faster cooling rate. These findings underscore potential robust fabrication larger precision efficiency.
