Abstract

Through our previous screening experiments for a new dental alloy design, anAu–11.9Pt–0.6Cu–0.5Snalloy was selected as a candidate in terms of good strength and surface properties. In this report, the effects ofIn(indium) on the microstructures and hardness of a dentalAu–11.9Pt–0.6Cu–0.5Sn–xInalloy (wherex = 0, 0.25, 0.5, 0.75, and 1.0 wt.%) was investigated. The hardness of theAu–11.9Pt–0.6Cu–0.5Sn–xInalloys increased with increasingIncontent up to 0.75 wt.% and then started to decrease with further increase inIncontent. Particularly, the alloy containing 0.75%Inexhibited noticeably high hardness of 172 Hv. With the addition ofInto theAu–Pt–Cu–Snalloy, grain size decreased and a large number of fine precipitates were formed. The precipitates were identified asPt3(Sn, In)by convergent beam electron diffraction (CBED) and nanospot energy dispersive spectroscopy (EDS). The increased hardness with the addition ofInwas attributed to the precipitation hardening ofPt3(Sn, In)and the grain refinement.
