“…Compared with HPDC, both the strength and elongation of rheomolded AZ91D reaches or exceeds even if the pouring temperature is at 640°C. It is well known that lowering the pouring temperature would promote the formation of equiaxed solidification [22][23][24]. Under the cooling effect of the injection cylinder, the melt with a low superheat may undercool quickly and abundant heterogeneous nucleation may occur throughout the slurry.…”

“…Under the cooling effect of the injection cylinder, the melt with a low superheat may undercool quickly and abundant heterogeneous nucleation may occur throughout the slurry. It results in the formation of numerous nuclei and the elimination of the columnar zone in the casting [22,23], and consequently, massive fine spherical a 1 -Mg are formed (Fig. 6d).…”

An advanced rheomolder, equipped with a thinwalled phone cover mold, was introduced and used to manufacture the AZ91D magnesium alloy. Effects of different processing parameters including pouring temperature, cylinder temperature and injection velocity on the microstructure and mechanical properties were investigated. The results showed that, with the decrease of pouring temperature or the increase of injection velocity, the size of a 1 -Mg decreases while the sphericity increases, and the porosity fraction reduces, which raise mechanical properties of rheomolded AZ91D. As the cylinder temperature decreases, the size of a 1 -Mg decreases and the sphericity increases initially and then remains relatively unchanged while the solid fraction increases continuously. Also, the cylinder temperature has a significant effect on mechanical properties of rheomolded AZ91D and the highest mechanical property is obtained at a cylinder temperature of 555°C. The optimal rheomolded AZ91D with tensile strength of 273 MPa and elongation of 7.2 % were obtained at the pouring temperature of 600°C, injection velocity of 2.1 m/s and cylinder temperature of 555°C. Compared with high pressure die-casting, the tensile strength and elongation were increased by 22.4 and 213 %, respectively.

“…The whole melt was undercooled and copious heterogeneous nucleation took place immediately throughout the melt. A large proportion of the nuclei survived and contributed to the formation of fine dendritic structures [15,16]. After pouring, the solidification of molten metals under pressure took place.…”

In this work aluminium based silicon carbide composite material with different percentage of silicon carbide and magnesium has been fabricated. Various tests such as XRF, hardness test, roughness test, tensile test, compressive test have been conducted to determine the various properties of the composite material. From the various tests it has been observed that with the addition of silicon carbide the hardness of composite material increases. This material is suitable for the manufacturing of gears for low and medium load application.
