Special Issue Information

Dear Colleagues,

Advanced lightweight structural metals, including aluminum (Al), magnesium (Mg) and titanium (Ti) alloys, are increasingly being used in the automotive and aerospace for weight reduction and for the increased demand of fuel economy. Developing innovative manufacturing processes increase the component performance and decrease the processing cost. Sheet metal forming technologies such as stamping, flanging, bending, hemming and trimming have been well established at room temperature (RT). Unfortunately, the poor RT formability of these lightweight metals, compared to steels, limits their high-volume and high-performance application.

Based on the advanced forming technologies, computational theory and numerical simulation, considerable efforts and significant progress, fundamentally and technologically, have been made on the wrought Al, Mg and Ti alloys. The present Special Issue on “Advanced Metal Forming Technologies - advanced experiment and integrated computational design” may shed light on bulk metallic genome “Crystal” corresponding to inter/intra-granular plastic deformation mechanisms such as slip, twinning, grain boundary sliding, grain size, recovery, recrystallization, texture, and yield asymmetry via experimentally metallurgical strategies (alloying and thermomechanical processing) and multi-scale modelings including thermodynamic/kinetic calculation, first principle calculation, molecular dynamic simulations, multi-phase field model, crystal plasticity model, continuum plasticity model, and finite element model. Thus, we invite researchers to contribute to this Special Issue focusing on the alloying–processing–microstructure–property relationship of lightweight metals via the advanced experimental characterization, novel metal forming technologies and Integrated Computational Materials Engineering (ICME) modelings.

An empirical potential under the formalism of second-moment approximation of tight-binding potential is constructed for an Al-Ni-Ti ternary system and proven reliable in reproducing the physical properties of pure elements and their various compounds. Based on the constructed potential, molecular dynamic simulations are employed to study metallic glass formations and their local atomic arrangements. First, a glass-formation range is determined by comparing the stability of solid solutions and their corresponding counterparts, reflecting the possible composition region energetically favored for the formation of amorphous phases. Second, a favored glass-formation composition subregion around Al0.05Ni0.35Ti0.60 is determined by calculating the amorphous driving forces from crystalline-to-amorphous transition. Moreover, various structural analysis methods are used to characterize the local atomic arrangements of Al0.05NixTi0.95-x metallic glasses. We find that the amorphous driving force is positively correlated with glass-formation ability. It is worth noting that the addition of Ni significantly increases the amorphous driving force configurations of fivefold symmetry and structural disorder in Al0.05NixTi0.95-x metallic glasses until the content of Ni reaches approximately 35 at%.
