Improving the strength and the toughness of Mg–Cu–(Y, Gd) bulk metallic glass by minor addition of Nb

Mg–Cu–Y–Ag bulk metallic glasses with enhanced compressive strength and plasticity

“…component) [10]. By employing this routine, we have investigated the effect of Be, Nb and rare earth elements on the mechanical properties of Mg-based BMG alloys, and found that the addition of proper elements with larger E and can obviously increase the fracture strength and toughness of BMG alloys [11][12][13][14]. Considering that Ag has larger E and and lower G/B than Mg [15], the mechanical properties of Mg-based BMGs can be expected to be improved by the substitution of Mg with Ag.…”

Mechanical properties and fracture mechanism of as-cast Mg77TM12Zn5Y6 (TM=Cu, Ni) bulk amorphous matrix composites

“…In order to overcome the brittleness of Mg-based BMGs, the synthesis of amorphous matrix composites by using ex situ [13] and in situ [14] methods were investigated, and 2-3% plastic strain was obtained. Recently, Li et al [15] and Zhang et al [16] have demonstrated that some elements, such as Ni, Nd and Nb can improve the fracture strength and the toughness of the Mg-based BMG alloys. However, in order to use Mg-based BMGs in engineering, plastic deformation, or ductility of this kind of materials is very important.…”

Numerical simulation on the microstress and microstrain of low Si-Mn-Nb dual-phase steel

“…In addition, element Nb can improve the strength and plasticity of dual-phase steel by refining the grain size during metadynamic recrystallization. Therefore, the Si-Mn-Nb dual-phase steel is one of the key materials in the area of high-strength steel for automobiles [9][10][11].…”
