The use of elemental metallic powders and in situ alloying additive manufacturing (AM) is industrial relevance as it offers the required flexibility to tailor batch powder composition. This solution has been applied AM nickel-titanium (NiTi) shape memory alloy components. In this work, we show that laser bed fusion (LPBF) can be used create a Ni55.7Ti44.3 alloyed component, but chemical composition build large heterogeneity. To solve problem three different annealing heat treatments were...
The plasticity of hexagonal titanium is reexamined based on the split slip modes phenomenon, revealing existence subslip in prismatic and pyramidal hcp systems. energetics dislocation emission motions were described using all-dimension relaxed atomic models crystal slip, calculated with density functional theory. proposed computational methodology generalized stacking fault energy concept respects all elastic effects arising within nucleation. As a result, improved accuracy has been obtained...
Molecular dynamics simulations and first-principles calculations are carried out on first order pyramidal plane (π1) of magnesium to study both compression twinning (CTW) dislocation slip. To this end, a generalized stacking fault energy analysis is employed dense (π1D) loose spaced (π1L) π1 planes. The crystal shearing resistance extracted by using minimum-energy path (MEP) finder called the nudged elastic band (NEB) method. MEP regarding 1¯012101¯1π1L slip system shows that unfaulted...
Unprecedented mechanical properties of the novel TWIP/TRIP titanium alloys are controlled by {332}<113> twinning and stress-induced martensitic transformation, which can operate separately, simultaneously or even in synergy, following a still unclear atomic-scale mechanism. Using ab initio calculations experimental observations, we show that be described as polymorphic solid-state transformation able to produce either twinned structures with unified path. The required lattice strains atomic...
Plasticity of hexagonal titanium–aluminum alloys depends on the solute concentration and order state Al atoms. Development short-range (SRO) modifies strengthening impacts competition between prismatic basal slip modes. Using ab initio calculations, we study interaction a screw dislocation with isolated atoms pairs in an hcp Ti existing ordered Ti–Al alloys. Calculated activation energies reveal pronounced hardening caused by addition for both systems, which become competitive. This is...
