Microstructure and mechanical property of the ECAPed Mg2Si/Mg composite

Recent Research on the Deformation Behavior of Particle Reinforced Magnesium Matrix Composite: A Review

“…Jia et al [54] carried out ECAP on the Mg 2 Si p /ZK60 composites, the results indicated that the UTS was increased from 154.8 to 270 MPa, and the elongation was improved from 4.5 to 17.5% after four passes of ECAP. Gan et al [55] performed ECAP on the in situ Mg 2 Sip/ Mg composites and found that the grain of Mg matrix was refined and the intensity strength of (0002) basal plane texture was weakened after the application of ECAP process. However, it was interesting to note that the grain size of Mg matrix changed a little during the subsequent ECAP process [55].…”

Microstructure and tensile properties of SiC nanoparticles reinforced magnesium matrix composite prepared by multidirectional forging under decreasing temperature conditions

“…Several conventional deformation processes, such as extrusion, rolling and forging [8][9][10], have been successfully used to enhance the strength and ductility of nanoparticles or micron-particles reinforced magnesium matrix composites. In recent years, severe plastic deformation (SPD), which can refine the grain size of metallic materials into submicrocrystalline and nanoscale, has been applied to process magnesium alloys [11][12][13][14][15][16]. Among SPD techniques, the best known are: accumulative roll-bonding (ARB), high-pressure torsion (HPT), multidirectional forging (MDF) and equal channel angular pressing (ECAP).…”

Using ARB process as a solution for dilemma of Si and SiCp distribution in cast Al–Si/SiCp composites

“…So, it is necessary to improve the mechanical properties of the cast composites by a secondary mechanical processing such as compressing, rolling, extrusion, forging, and severe plastic deformation (SPD) methods including equal channel angular pressing (ECAP). Some investigations such as Mitra et al (2004) and Gana et al (2009) have shown that these mechanical processes can minimize or eliminate porosity of cast composites and also improve the reinforcement-matrix interfacial bonding, with a subsequent increase in mechanical properties. According to Wu et al (2010) and Lee and Subramanian (1992), mechanical processes can improve reinforcement distribution in cast composites.…”
