X-ray diffraction and microstructural study of PFM precious metal dental alloys under different metallurgical conditions

Determination of the electrical and thermal properties of Al-Sn-Zn alloys

“…SEM and EDX measurements were made. From the XRD patterns, the crystal symmetry and cell parameters of the samples were obtained by computer-interfaced advanced diffractometer Bruker AXS D8 XRD [17][18][19][20][21][22]. This machine is measuring between angular ranges 0 o < 2 < 90 o with using Bragg-Brentano geometry.…”

The electrical, thermal conductivity, microstructure and mechanical properties of Al–Sn–Pb ternary alloys

“…From the XRD patterns, the crystal symmetry and cell parameters of the samples were determined [16][17][18][19][20][21].The microstructures of the samples were characterized using a LEO 440 SEM equipped with an EDX spectrometer as well as a computer-controlled image analyzer. The Al, Pb, and Sn compositions of the samples were determined using the EDX technique.…”

“…The samples were cut transversely into ~3-5 mm long sections and then grounded for the electrical conductivity measurements [16][17][18][19][20]. The temperature of the sample was adjusted by a controllable Nabertherm furnace and measured using a 0.5 mm standard K type thermocouple which was placed very close to the sample and detected with the Keithley 2700 multimeter.…”
