Ductility and structure of some cobalt-base dental casting alloys -

The shape of the clasps on removable partial dentures often has to be adjusted by bending. Occasionally they fracture during the small plastic deformation that takes place during the adjustment. The tendency to brittle failure of three Co-Cr-Mo alloys for prosthetic use with different carbon and chromium contents was investigated by tensile testing

Ductility of a dental Ag-Pd-Cu-Au alloy -

A silver-palladium type of dental alloy for fixed restorations has been investigated with regard to the ability of the material to be plastically deformed in uniaxial tensile testing after two different age-hardening treatments. A certain degree of ductility is required for the burnishing of the margins.
