in this paper, the properties and microstructure of foam glasses obtained from the wasted cathode ray tube (crt) display panels were investigated. the foam glasses were prepared at the temperatures of 850, 950 and 1050c using 2, 4, 6 and 8 wt.% silicon carbide (sic) as the foaming agent. the physical and mechanical properties of the samples including the density, porosity, four-point bending s...

AlxCoCrFeMnNi high-entropy alloys with different aluminum concentrations (x = 0.5, 1, and 1.5 at%) were synthesized by mechanical alloying followed consolidation using two sintering methods, conventional (CS) high-frequency induction heat + (HFIHS CS). The results show the presence of FCC, BCC, B2ordered phases in all systems, regardless method. BCC phase exhibits morphological changes (cuboida...

Productivity in the manufacture of aircrafts components, especially engine must increase along with more sustainable conditions. Regarding machining, a solution is proposed to cutting speed, but engines are made very difficult-to-cut alloys. In this work, comparison between two tool materials, namely (a) cemented carbide and (b) SiAlON ceramics, for milling rough operations Inconel® 718 aged co...
