Microstructural evolution of thixomolded AZ91D magnesium alloy with process parameters variation

Microstructure and tensile properties of thixomolded magnesium alloys

“…The microstructure in both alloys consisted basically of globular primary ␣-Mg surrounded by the eutectic structure. Such a microstructure could be considered as suspension of solid primary ␣-Mg particles dispersed in a liquid matrix in the absence of dendrites [9,30]. The eutectic structure consisted of a mixture of eutectic ␣-Mg and intermetallic compound ␤-Mg 17 Al 12 , which was also reported by Fan et al [5] and Czerwinski et al [13].…”

“…Thixomolding ® , a semisolid metal processing technology for producing net-shape magnesium parts in one step in a single machine, has received considerable interest in recent years [7][8][9][10]. Tensile properties of thixomolded AZ61A [11], AM50B [12] and AZ91D [9,10,12,13] magnesium alloys have been studied and correlated with the processing conditions such as shot velocity, barrel temperature, injection pressure, etc.…”

“…Tensile properties of thixomolded AZ61A [11], AM50B [12] and AZ91D [9,10,12,13] magnesium alloys have been studied and correlated with the processing conditions such as shot velocity, barrel temperature, injection pressure, etc. Some authors reported the creep strength of thixomolded AZ91 alloy [14,15], while some reported microstructural evolution of friction stir welded, thixomolded magnesium alloys AZ91 [16,17] and AM60 [18].…”

Microstructure evolution of AM60 magnesium alloy semisolid slurry prepared by new SIMA

“…Some studies on the microstructure evolution of semisolid slurry of A356 aluminum alloy deformed severely by ECAP [12], and that of Mg-9Al-1Zn alloy produced by mechanical stirring under low shear [13], and that of thixomolded AZ91D magnesium alloy [14] have been carried out. However, little was reported on the microstructure evolution of AM60 magnesium alloy semisolid slurry prepared by new SIMA.…”

Microscopic characterization of semi-solid aluminium alloys

“…Atkinson et al [13][14] studied the microstructural coarsening and recrystallisation of semi-solid aluminium alloys. In addition, some researches focused on the semi-solid forming of other materials [15][16][17][18][19][20][21]. Luo et al [15] studied the mechanical behavior and microstructure during compression of semi-solid ZK60 magnesium alloy at a high solid content.…”
