“…In addition, compared with the Mg matrix PMMCs strengthened by transition metal elements or rare earth elements [27,28], the 8.2AlN in /Mg-8Al composite has lower density and cost. Furthermore, compared with the Mg-Al alloy reinforced by SiC, TiC, TiB 2 and AlN particles [8][9][10][15][16][17], the 8.2AlN in /Mg-8Al composite is not only easy to synthesize but also has better mechanical properties. Therefore, this paper may bring new insights for synthesizing Mg composites utilizing various methods.…”

In this paper, 8.2AlN/Mg–8Al composites reinforced with in situ and/or ex situ AlN particles have been synthesized. The in situ-formed AlN particles are nano-sized, performing as particle chains. It has been clarified that the in situ AlN particles are more efficient than ex situ particles for the enhancement of mechanical properties. The in situ-prepared composite exhibits improved density, hardness and compressive strength compared to the ex situ ones. This work may be referred to for designing particle-reinforced Mg composites by various methods.

“…The network-like of particle distribution was determined by theparticles and the solid/liquid interface of Mg during solidification. particle near the solidification front will either be captured or pushed due to quickly move forward of solid/liquid interface front during magnesium melt containing good dispersed ceramic particles [15,16]. Therefore, compared with particle distribution in magnesium melt, solidified composites would have the new changes.…”

The present work aims to research the treatment processing of magnesium reinforced with 1 μmsilicon carbide particle (SiCp) using stir casting combined by ultrasonic vibration. Present studies have been done on six different materials: (a) AZ31B alloy without particles, (b) 5 vol.% SiCp/AZ31B composites fabricated with different semi-solid stirring time (5 min, 10 min, 15 min and 20 min), (c) composite with 20 vol.% SiCp. The effects of 1 μm/SiCp pretreatment and stirring time on microstructure and interfacial wettability as well as mechanical properties of the materials were confirmed. Both short and long stirring time for the particle dispersion brought particle agglomeration. Results of SEM microstructure and tensile properties exhibited that the optimal stirring parameters of 625 °C/1500 rpm/15 min are exploited, and 20 vol.% SiCp/AZ31B composite was fabricated by the optimal stirring parameters. The application of optimal stirring parameters for the treatment resulted in homogeneous particle distribution. The addition of SiCp leads to a reduced matrix grain, and 20 vol.% SiCp/AZ31B composite showed smaller grain size than. 5 vol.% SiCp/AZ31B composite. The interface between SiCp and matrix is clear and interfacial wettability well. Tensile test results show that with increasing SiCp content, strengths increase while ductility decreases.

In the past, aluminium alloys greatly influenced the aerospace, automotive, and medical fields, particularly in biomedical applications. However, in contemporary times, magnesium alloys have emerged as highly promising materials for biomedical applications and casting processes. This study focuses primarily on magnesium metal matrix composites, utilizing ZE41 magnesium alloy as the base material. ZE41 possesses a high ductile nature, excellent mechanical strength, and impressive wear and corrosion resistance properties. In this experimental work, Nano-Graphene is employed as reinforcement particles. The investigation employs the stir casting methodology to create magnesium metal matrix nanocomposites. The responses considered in this work are compressive strength and microhardness. Both responses undergo Taguchi statistical analysis with varying process parameters. A Taguchi L16 orthogonal array is utilized to assess the optimization parameters of the stir casting process. The parameters include reinforcement percentage (3%, 6%, 9%, and 12%), stirring speed (300, 400, 500, and 600 rpm), melting temperature (700, 750, 800, and 850°C), and stirring time (15, 20, 25, and 30 mins). The mechanical properties, specifically compressive strength and microhardness, are thoroughly examined. The highest compressive strength, reaching 276.66, was achieved with 12% reinforcement, a stirring speed of 400 rpm, a melting temperature of 800°C, and a stirring time of 15 mins. Similarly, the maximum microhardness, recorded at 172 VHN, was influenced by 6% reinforcement, a stirring speed of 600 rpm, a melting temperature of 800°C, and a stirring time of 20 mins.
