Influence of the residual oxygen amount in reduced graphene nanoplatelets on microstructure and mechanical properties of ZK60 matrix composites

Recent advances in mechanical properties of Mg matrix composites: a review

“…5,41,42 In the literature, there are recent studies on Mg matrix composite produced by SC. [43][44][45][46][47][48][49][50][51][52][53][54] Fang et al 43 produced AZ31/Al 3 Fe composites by SC followed by hot rolling. The hot rolled samples were homogenised at 693 K for 12 h. Cross-rolling was performed at 673 K, and the samples were cooled in the air when the total plastic deformation was 70%.…”

“…Du et al 53 performed transmission electron microscopy (TEM) analysis of ZK60/GNPs composites for interfacial characterisation (Figure 1). The authors stated that the GNPs particles were well embedded and integrated with the matrix.…”

“…The increase in hardness is attributed to hard particles greatly restricting local plastic deformation during indentation. 44,45,53,124,125 Subramani et al 46 attributed the increase in hardness to grain refinement, secondary phase particles, and strain hardening. Yellapragada et al 49 reported that the reinforcement particles increased the hardness by increasing the load-carrying capacity, but when the reinforcement content exceeded the critical level, the hardness decreased due to particle 43 agglomeration.…”

“…142 Ragupathy et al reported that the enhanced tensile strength of AZ91/SiC-Gr composite was attributed to a strong bonding between matrix and reinforcement. Du et al 53 reported that in-situ formed MgO particles and semi-coherent interface of MgO/Mg improved the interface bonding between matrix and GNPs and increased the load-bearing capacity. Thanks to the formation of MgO, good wettability and improved interfacial adhesion are provided for ZK60/GNPs composites.…”

“…Different researchers reported that the Orowan mechanism contributed to the increase in yield strength. 44,45,53,[60][61][62]82 Borodianskiy et al 44 reported that the motion of dislocations was hindered by reinforcement particles due to the formation of Orowan loop, which leads to an increase in strength. As a result, the Orowan strengthening was identified as an important mechanism for the increase in yield strength.…”
