The gold solder, gold alloy interface

Australian Dental Journal, 1977
Abstract— With soldering the physical properties of the basis metal must be maintained and a minimum of molten metal is used. An examination of joints in 17 gauge platinized gold wire is made with 18 k gold solder following quenching immediately after flow and cooling in air; there is a widening of grain boundaries and intergranulation penetration in ...

Hardening of Gold-Based Alloys

Journal of Dental Research, 1977
The relationships between composition, heat treatment, hardness and microstructure have been investigated for a number of commercial dental casting alloys and for several series of experimental gold-silver-copper compositions. The results indicate that at least two distinct hardening mechanisms must occur in these alloys.

Laser Welding of Gold Alloys

Journal of Dental Research, 1972
A neodymium glass laser was used to produce weld joints between test pieces of four different casting gold alloys. The mechanical properties of the welds were determined and their microstructures were evaluated. The results of this study indicate that laser welding of dental casting gold alloys is metallurgically feasible.

Low-gold fixed prosthodontic alloys

The Journal of Prosthetic Dentistry, 1982
Abstract Properties, heat treatment characteristics, composition, and microstructure of three low-gold dental casting alloys were studied. The materials exhibited vast compositional differences but strikingly similar structural features. Laboratory evaluation of the properties of these test materials suggest their potential use in fixed ...
