Evaluation of whisker alignment and anisotropic mechanical properties of ZK60 alloy reinforced with SiCw during KOBO extrusion method

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

“…Another advantage of this method is that higher deformation is achieved and does not require annealing, and recrystallisation is not observed. 54 ARB includes steps such as rolling, cutting, stacking and bonding. 99 High temperatures are used to improve bonding in the ARB process, but lower temperatures are recommended to prevent grain growth.…”

“…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%.…”

“…The authors reported that the significant deformation leads to the formation of sub-grained boundaries. In the KOBO extrusion process, the local temperature rises 54 rapidly, and dynamic recovery and dynamic recrystallisation occur. 113 The perpendicular cross-section microstructure of the composite can be seen in Figure 9(d).…”

“…Subramani et al 46 reported that GNDs form due to a large difference in CTE between the matrix and hybrid reinforcements. The GNDs at the interface regions behave as a 54 barrier to dislocation movement and lead to an increase in strength. 84 Wang et al 60 reported that new dislocations were formed during the cooling process due to difference in the CTE between the matrix and reinforcement.…”

The Effect of Adding V and Nb Microalloy Elements on the Bake Hardening Properties of ULC Steel before and after Annealing

“…Despite the increasing development of lighter materials, steel sheets are still considered the most important consumables in the automotive industry due to their properties such as corrosion resistance with the use of coating, high energy absorption capacity during collisions, high work hardening rate, aging ability, and excellent paintability [ 5 , 6 ]. Although materials such as aluminum, magnesium, and plastics have been implemented in the manufacture of car parts to reduce their weight, high-strength steels in the form of sheets are the most important option due to their wide range of strengths, chemical compositions, and surface qualities [ 4 , 7 , 8 , 9 ]. If high-strength steel sheets are used in the construction of an automotive body, it is possible to use sheets with a lower thickness in the construction of the automotive body without reducing the resistance to indentation, which is considered one of the determining parameters of automotive safety, and as a result, the weight of the automobile can be significantly reduced.…”
