“…They found that the additions of CdCl 2 increased the weld penetration dramatically, and good weld appearances of welded joints were achieved. Lin et al [3] researched the evolution of microstructures and mechanical properties of AZ31B magnesium alloy weldments with active oxide fluxes and gas tungsten arc welding (GTAW) process. They found that the penetration depths increased significantly with the additions of SiO 2 , Fe 2 O 3 , and Al 2 O 3 fluxes.…”

The effects of SiC particles on the morphologies, microstructures, and mechanical properties of tungsten inert gas welded AZ31 magnesium alloy joints with TiO 2 flux coating were studied. The results showed that an increase in the amount of the TiO 2 coating improved the weld penetration and the depth/width (D/W) ratio of the TIG welded AZ31 magnesium alloy seams. The a-Mg grains of FZ of welded joints refined gradually with the addition of micro-sized SiC (<30%) =nano-sized SiC (<40%) particles in coatings, and then coarsened when more SiC particles added. In addition, the microhardness of the FZ and ultimate tensile strength of the welded joints increased with the addition of SiC particles, and nano-sized particles have more strong efficiency on the improvement of mechanical properties compared with micro-sized SiC particles.

“…They explored the casting of AM60/AL 2 O 3p MMCs, the strengthening of bar stock manufactured using an equal-channel angular pressing, and the binding ability and tribological behavior of base materials. Lin et al [4] investigated the microstructural evolution and mechanical properties of AZ31B magnesium alloy. Jacob et al [5] proposed the use of Taguchi method to optimize the control variables to reduce casting defects.…”

This study investigated the influence of vacuum casting parameters on defects in magnesium alloy as well as changes in the mechanical properties of these alloys and microstructural evolution under the effects of annealing. We used the Taguchi method in conjunction with an X-ray image detector to determine the percentage of area affected by internal defects, the results of which were verified experimentally. X-ray images of magnesium alloy specimens were filtered, binarized, and edge enhanced. The calculated area of internal defects was then used to optimize process parameters according to multiple performance indicators. Based on the average signal-to-noise ratio, Batch 1 (720 • C, 30 torr, 2 h, steel, and 120 min of argon gas injection) and Batch 8 (780 • C, 30 torr, 1 h, steel, and 120 min of argon gas injection) were both deemed optimal. The uniformity in the percentage of internal defect area observed in samples from Batch 8 is an indication of stability.
