This research created hot-pressed composites of the AA6063 matrix with varying concentrations ZrO2 (0.25, 0.5, and 1 wt %). At sliding speeds 80, 120, 150 mm/s, wear performance specimen was studied at loads 10 N, 15 20 25 N. The authors analyzed counter-face material, debris, worn surfaces to learn about mechanisms. Developing these three machine learning (ML) algorithms evaluate ability predi...

هیدروفرمینگ لوله به‌طور گسترده، در تولید قطعات ساختاری اتومبیل استفاده می‌شود. یکی از خصوصیات تولید‌شده با این فرایند، نسبت استحکام به وزن بالا می‌باشد. لولۀ فشار پایین، روش‌های پیشنهاد‌شده برای حل مشکلات قبیل نیاز بالای سیال و آب‌بندی روش انجام پایین لوله، شبیه فشردن جسم جامد است آن برخلاف بالا، قالب بالایی طول فرایند ثابت نبوده هم‌زمان اعمال داخلی حرکت کرده را تحت قرار می‌دهد. مقاله، لوله‌های...

Information is presented on the conceptualization, experimental study, and numerical process simulation of tailor heat treated aluminum alloy blanks. This concept intended to improve forming behavior parts in challenging conditions. The implementation requires precise control laser treatment parameters within a suitable industrial framework. study details material properties, parameters, result...

Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...
