The invention relates to cold rolled medium manganese steel with an ultra-high strength and ductility product and a preparation method thereof, and belongs to the technical field of steel for automobiles. The key point of the cold rolled medium manganese steel with the ultra-high strength and ...
whereas substantial uniform ductility is associated with a combination of transformation and twinning induced plasticity during deformation. Additionally, very low volume percent of voids (∼0.1 %) along with high strength-ductility shows excellent printability of the CS-HEA using laser-based additive ...
Noting the structure of the developed relations, we use dimensional analysis to formulate a version of the ductility-strength and strength-ductility relations that are dimensionless and independent of the seismic hazard intensity. These novel, dimensionless master relations are the μμ-R*-H/B-κκ...
It is thought that one reason for the lack of ductility is that the development of f1011g—f1012g double twins (DTW) cause premature failure of magnesium alloys. Here we show with a magnesium alloy containing 4 wt% lithium, that the same impressively large compression failure strains can ...
the high aluminium content of these materials leads to problems. Rahnama says: “The addition of aluminium leads to the formation of hard-but-brittle phases such as kappa-carbide (k-carbide) and B2 intermetallic compounds.” These make the steels hard, but limit their ductility, so they are ...
Zha et al. [175] obtained high strength and ductility in Mg-1.1Al-1.1Zn-0.2Sn-0.3Ca alloy by sub-solidification followed by hot rolling and annealing process, and the yield strength and elongation at room temperature are ∼ 249 MPa and ∼ 14%, respectively, where the contribution of ...

Here we report a novel selective laser melting process to simultaneously enhance the strength and ductility of stainless steel 316L by in-process engineering its microstructure into a <011> crystallographic texture. We find that the tensile strength and ductility of SLM-built stainless steel 316L ...
The dependence of yield strength, uniform elongation, and toughness on grain size in metallic structural materials was discussed. The toughness is defined as the product of yield strength and uniform elongation. The yield strength versus grain size can be well described by the Hall-Petch relation;...
Thus, the role of brittle resin with less ductility has less effect on the impact behaviour. Furthermore, thermoplastic resins can also increase the absorbed energy and impact strength compared to thermoset materials [19,192]. At low impact energy, the bending of fibres and the resin are ...
