Effect of Solidification Time on the Microstructure and Physical Properties of Dental Gold Casting Alloys

Abstract

SYNOPSIS IN INTERLINGUA

LE EFFECTO DEL TEMPORE DE SOLIDIFICATION SUPER LE MICROSTRUCTURA E LE PROPRIETATES PHYSIC DE ALLIGATOS FUSIONAL DE AURO DENTAL.-Esseva determinate: le longor del tempore requirite pro obtener solidification, le dimensiones del grano, le duritate de Vicker, le grado de porositate, e limite del elasticitate in flexion, e le modulo del elasticitate de specimens de alligato de auro dental fusionate a 5 differentes temperaturas. Le resultatos indica que fundition a alte temperatura prologa le solidification del alligato e resulta in un producto con plus grossier structura granular, plus basse duritate, e extense porositate, e plus basse limites de elasticitate que productos fusionate a plus basse temperaturas.
