The initial microstructure and mechanical properties of composite powders have a vital role in determining the microstructure and mechanical properties of the subsequent consolidated bulk composites. In this work, Al-based matrix composite powders with a dense and uniform distribution of metallic glass nanoparticles were obtained by high-energy milling. The results show that high-energy milling...
The transport properties, including electrical resistivity , thermopower S , and thermal conductivity of bulk metallic glass alloys Cu64Zr28.5Ti7.1, Cu62.3Zr23.7Ti10, Cu60.6Zr26.9Ti12.5 and Cu58.8Zr26.2Ti15 in the temperature range 10–300 K are reported. The temperature variations of electrical resistivity in these alloys, with a negative temperature coefficient, are found to be rather weak. Th...
This study evaluated the strength required to remove glass-fiber and metallic cast posts with different lengths. Sixty endodontically treated canines were included and their roots were embedded in acrylic resin after discarding the crowns. Samples were randomly assigned to 3 groups according to the post length (n = 20): I- 6 mm, II - 8 mm and III- 10 mm. Each group was divided into 2 subgroups ...
