1Effect of intermetallic compounds on the fracture behavior of dissimilar friction stir welding joints of Mg and Al alloys显示文摘Joining Mg to Al is challenging because of the deterioration of mechanical properties caused by the formation of intermetallic compounds(IMCs) at the Mg/Al interface. This study aims to improve the mechanical properties of welded samples by preventing the fracture location at the Mg/Al interface. Friction stir welding was performed to join Mg to Al at different rotational and travel speeds. The microstructure of the welded samples showed the IMCs layers containing Al12Mg17(γ) and Al3Mg2(β) at the welding zone with a thickness(< 3.5 μm). Mechanical properties were mainly affected by the thickness of the IMCs, which was governed by welding parameters. The highest tensile strength was obtained at 600 r/min and 40 mm/min with a welding efficiency of 80%. The specimens could fracture along the boundary at the thermo-mechanically affected zone in the Mg side of the welded joint.Amir Hossein Baghdadi Zainuddin Sajuri Nor Fazilah Mohamad Selamat Mohd Zaidi Omar Yukio Miyashita Amir Hossein Kokabi 2019International Journal of Minerals,Metallurgy and Materials2019,26,10:5

3Wear behavior of copper-containing ferritic iron under a dry sliding condition显示文摘The effect of solute Cu and Cu precipitates on the wear behavior of ferritic iron under an unlubricated condition was investigated.The specific wear rate of Cu-containing steel abruptly decreased up to 50 N of load,and then gradually decreased with further increased load.The specific wear rate of the as-quenched specimen,in which Cu was in a solid solution,was the lowest among all the specimens at low loads,and all specimens had almost the same specific wear rate at high loads.Subsurface observation showed that the hardness increments of all specimens decreased with increased depth below the worn surface.The as-quenched specimen had a relatively large depth of deformed region than the other specimens even though the increments in hardness were almost the same for all specimens at low loads.With the same hardness at an unworn state,the as-quenched and over-aged specimens exhibited a substantial increase in hardness and large deformed regions below the worn surfaces.This finding indicated that the enhancement in plastic deformation and work hardening led to the decrease in the specific wear rate of the as-quenched specimen at low loads and the improvement in the wear resistance of all specimens at high loads.Junaidi SYARIF Agung ISWADI Mariyam Jameelah GHAZALI Zainuddin SAJURI Mohd Zaidi OMAR 2013Journal of Zhejiang University-Science A(Applied Physics & Engineering)2013,14,12:0
