The effect of section size on the mechanical properties of wrought gold wires.

R ESULTS of tensile tests made with the nonprecious metals, notably aluminum, have proved that section size is not a factor in determining proportional limit, provided the grain size is not excessive.' However, these tests were made on specimens varying from 0.500 to 0.050 inches in diameter, and wrought dental gold wires, in which the diameter is as small as 0.030 inches, are often used. It is...

Mechanical properties and grindability of dental cast Ti-Nb alloys.

Aiming at developing a dental titanium alloy with better mechanical properties and machinability than unalloyed titanium, a series of Ti-Nb alloys with Nb concentrations up to 30% was made. They were cast into magnesia-based molds using a dental casting machine and the mechanical properties and grindability of the castings were examined. The hardness of the alloys with Nb concentrations of 5% a...
