The addition of lithium to high strength aluminum alloys significantly improves specific strength as is the case with AA 2195. However, unlike non-lithium containing alloys, such as AA 7075, lithium containing alloys display anisotropic mechanical pr

The dynamic yielding and tensile fracture (spalling) behavior of an annealed aluminum–magnesium alloy is investigated using symmetric plate impact experiments. The Hugoniot elastic limit displays upper and lower yield points, with the lower yield p

Investigations of the production of thin-walled steel alloys through the gas carburization of structures made from reduced and sintered metal oxide powders were performed. Extrusions with low-alloy steel composition were produced successfully without

Zirconium diboride and a zirconium diboride/tantalum diboride mixture were synthesized by solution-based processing. Zirconium n-propoxide was refluxed with 2,4-pentanedione to form zirconium diketonate. This compound hydrolyzed in a controllable fas

Potential interconnect alloys of Fe–Cr and Fe–Ni–Cr were fabricated via extrusion of metal oxide pastes followed by heat treatment in hydrogen. Thermal expansion of the different alloys was measured and compared with that of yttria-stabilized z

The metastable liquidi in the Al–In, Al–Bi, and Al–Pb systems were assessed through the thermodynamic modelling of the liquid miscibility gaps. The subregular solution model was applied to describe the Gibbs free energy of liquid phases and the

The microstructure of most as-cast superalloys is highly anisotropic and inhomogeneous. In precipitation hardenable materials it is desirable to know the precipitate dissolution temperature to homogenize the microstructure and tailor the size and dis

A method for the rapid fabrication of homogeneous potential interconnect alloys from metal oxide precursors and evaluation of their thermal expansion mismatch to solid oxide fuel cells is described. Pastes of metal oxide powders were extruded into ho
