Abstract
This study systematically investigates the microstructure, mechanical, and corrosion properties of hot-extruded Al3102 alloy flat tube, with direct comparisons to as-cast equivalents. Microstructural analysis revealed that both materials primarily consist of an aluminum matrix, with widespread distribution of Al₆(Mn,Fe)-type precipitates in their initial structures. The flat tube exhibited an average..... More

Abstract
A modified alloy (Al-0.7Mn) was designed and fabricated with an increased Mn content up to 0.7wt.% and a controlled Fe content of 0.1wt.% and compared with the conventional Al3102 (Al-0.3Mn) alloy using the air-slip casting process. Both alloys were homogenized at 510°C for 10 hours and then air-cooled. The microstructure,..... More

Abstract
This study investigated the high-temperature wear characteristics of Ta-10W alloy, composed of 90% tantalum and 10% tungsten, known for its high melting point, excellent corrosion resistance, and oxidation resistance. Wear tests were conducted using a ball-on-disc method with alumina balls at temperatures of 200°C, 400°C, 600°C, and 700°C. The results..... More

Abstract
In this study, we designed and manufactured a new Fe-bearing Al-10Si-Mg casting alloy (F alloy) and investigated its microstructure, mechanical properties, and thermal conductivity. Two types of Fe-bearing Al-10Si-Mg alloys were used: the Conventional-F alloy, injected at 720 ℃ and cooled by water quenching, and the Superheated-F alloy, heated to..... More

Abstract
This study investigated the effect of the electromagnetic stirring (EMS) process on the microstructure and mechanical properties of hyper-eutectic Al-15 wt.%Si alloy. The tensile and high-cycle fatigue properties of the EMS Al-15wt.%Si alloy were examined and compared with conventional direct chill (DC) cast alloy. The initial microstructure of the as-cast.....

Abstract
A Ni-Cr-B-Si-C coating layer was manufactured on a plate of Fe base alloy using a laser cladding process, and the microstructural and mechanical properties of the laser cladded coating layer and a Ni electroplating layer (used as a reference material) were investigated. To identify the microstructural and mechanical properties, scanning..... More
