“…Table 5 summarizes the composition, synthesis method, and mechanical properties of typical Ti-based BMG composites [153,[170][171][172][173][174][175][176][177][178][179][180]. It is found that most developed Ti-based BMG composites are of an in situ β-phase dendrite-reinforced type, as β-Ti possesses good ductility and a low modulus compared with hexagonal α-Ti.…”

“…However, the microstructure of BMG composites prepared via copper mold casting is not always uniform because of the cooling rate difference. Zhang et al [178] introduced a new technology named Bridgman solidification, which ensures the uniform microstructure of the prepared BMG composites by precisely controlling the processing parameters, but the corresponding equipment is more complex than traditional arc-melter. Moreover, the enhancement of ductility is always obtained at the price of lower strength.…”

Abstract:Ti-based bulk metallic glasses (BMGs) are very attractive for applications because of their excellent properties such as high specific strength and high corrosion resistance. In this paper, we briefly review the current status of the research and development of Ti-based bulk metallic glasses. Emphasis is laid on glass-forming ability, mechanical properties, corrosion resistance, and biocompatibility.

“…So the Mg matrix composites attract large attention in recent years due to the more advantageous mechanical properties than the Mg matrix alloys. The reinforcements of composites have long fibers, short fibers, whiskers or particles, interpenetrating phase and etc [4,5,6]. The Mg alloys interpenetrated by steel materials have such special microstructure characteristic as continuous and tri-dimensional, inter-twisting and interpenetrating reinforcement with Mg matrix.…”

The interpenetrating magnesium composites reinforced by three-dimensional braided stainless steel wire reinforcement were fabricated. And, the deformation behavior of materials was analyzed in four extrusion velocities by DEFORM-3D software. The results show that with the increases of extrusion velocities, the equivalent stress values exhibit a gradually increasing and then decreasing trend. Owing to the effect of three dimensional reinforcement, the basal plane orientation occur tilt. And, the microstructure turns refined.

“…However, the poor workability of wrought magnesium alloys limit their extensive application which attribute to their hexagonal crystallography and the associated lack of sufficient independent slip systems at room temperature. The hot extrusion process can activate the non-basal slip system such as prismatic and pyramid slip systems at evaluated temperature [4,5].…”

The three-dimensional finite element (FE) numerical simulation of extrusion forming of AZ31 matrix magnesium alloy was analyzed in four extrusion velocities. The flow pattern and the influence of extrusion velocity for the temperature, the distribution of effective stress and strain of composites were analyzed. The results showed that, when the extrusion velocity increased from 1.5 mm/s to 4.5 mm/s, the heat flux under steady extrusion state would change from-2.77e+004 (Wm2) to 1.14e+005 (Wm2), meanwhile the effective stress and strain increased at first and then decreased, and the average effective strain and stress value were smallest when v = 4.5 mm/s. It showed that along with the increase of the extrusion velocity, the rise degree of the temperature increased and the distribution of the effective stress and strain tended to be more evenly. Finally, the best extrusion technical parameters of AZ31 magnesium alloy were determined, that was the extrusion velocity was equal to 4.5 mm/s when extrusion ratio was 25 and extrusion temperature was 350 °C.
