The rechargeable lithium ion (Li-ion) battery market was $11.8 billion in 2011 and is expected to increase $50 by 2020. With developments consumer electronics as well hybrid electric vehicles, Li-ion batteries demand will continue increase. However, are not widely recycled because currently it economically justifiable (in contrast, at present more than 97% lead-acid recycled). So far, no commercial methods available recycle with different cathode chemistries efficiently. Considering our...
Single-phase body-centered cubic (bcc) refractory medium- or high-entropy alloys can retain compressive strength at elevated temperatures but suffer from extremely low tensile ductility and fracture toughness. We examined the toughness of a bcc alloy, NbTaTiHf, 77 to 1473 kelvin. This alloy's behavior differed that comparable systems by having over 253 MPa·m
Since commercial production of aluminium by the Hall-Heroult process, use and its alloys has been widespread, applications continue to increase. The casting process always a major manufacturing method for based products, parts have produced using all traditional processes. However, recent advances in die technology, coupled with improvements materials, made most commonly used producing alloy castings. Despite innovations technology that significantly expanded cast development complementary...
The exceptional mechanical properties, particularly at cryogenic temperatures, of the equiatomic CoCrNi alloy are documented in numerous published studies. Similar to CoCrFeMnNi (so called Cantor alloy), from which ternary was derived, possesses low stacking fault energy that promotes complex deformation modes, as well activation twinning ambient temperatures and increased strain. In addition outstanding mechanisms, chemical short-range order face-centered cubic (FCC)-hexagonal close packed...
To meet the growing demand for transportation and energy consumption around world, more efficient turbine engines power generators with higher operating temperatures are needed, which require alloys retained strength levels at elevated temperatures. In past decade, refractory complex concentrated (RCCAs) have gained prominence through numerous reports of superior strengths homologous compared to those conventional super alloys. However, these RCCAs, comprised transition metals from subgroups...
The crystal structure and electrochemical properties of LiNi1/3Mn1/3Co1/3O2 (NMC) synthesized from a lithium ion battery recovery stream have been studied previously. In this report, we study the Cu impurity effects on NMC in detail. difference structures were examined for pure copper included products. Scanning electron microscopy figures show that precursor particles are slightly bigger than with impurity. After undergoing 150 cycles at 2C, X-ray diffraction refinements results lattice...
Most metal additive manufacturing approaches are based on powder-bed melting techniques such as laser selective or electron beam melting, which often yield uncontrolled microstructures with defects (e.g., pores microcracks) and residual stresses. Here, we introduce a proof-of-concept prototype of 3D freeform fabrication process by direct writing metallic alloys in the semi-solid regime. This is achieved through controlling particular microstructure rheological behavior alloy slurries,...
