This study carried out the microstructural characterization, by light microscopy, of sintered SiC in the presence of liquid phase at temperatures of 1800, 1850 and 1900 ºC, added with Al2O3 and Y2O3 a
Aluminum alloys of the ANSI series 319 present Si and Cu as the main alloying elements and the mechanical strength of these alloys can be improved by the precipitation of the metastable Al2Cu phase du
OBJECTIVE: The aim of this study was to evaluate the microhardness in pressing layers of prefabricated modified acrylic resin teeth. METHODS: Lower first molar teeth with two (Biotone(r) IPN and Biofo
