Ion release from experimental Au–Pt-based metal–ceramic alloys [PDF]

open access: yesDental Materials, 2010
The aim of the study was to assess the effect of individual metallic elements within experimental Au-Pt-based dental alloys for porcelain veneering on ion release.A binary Au-10at% Pt alloy (AP10) was designed as a parent alloy. Six ternary AP10-X (X=In/Fe/Sn/Zn) and four quaternary (AP10-In2)-Y (Y=Fe/Sn/Zn) alloys containing oxide-forming elements, X ...

Impact of experimental conditions on material response during forming of steel in semi-solid state [PDF]

open access: yes, 2010
Semi-solid forming is an effective near-net-shape forming process to produce components with complex geometry and in fewer forming steps. It benefits from the complex thixotropic behaviour of semi-solids.
