High-frequency induction heated sintering of ball milled Fe-WC nanocompositesT. Zanganeh2,A. Najafi22. Department of Materials, Saveh Branch, Islamic Azad University, Saveh, Iran摘 要:Fe-WC nanocomposites were successfully fabricated by high-frequency induction heated sintering of ball milled nanostructure powders. The ball milled powders were......

powders were obtained via a patented reaction ball milling technique. The Sn melt reacted with the solid-state Cu during the milling process at different temperatures for different intervals. Two kinds... mechanism and advantages were discussed in comparison with that of high-energy ball milling. The results show the solutionizing of Ni powders in the Cu6Sn5 intermetallic. Key words: Cu-Sn binary......
Thermal Conductivity and Tensile Properties of Carbon Nanofiber-Reinforced Aluminum-Matrix Composites Fabricated via Powder Metallurgy: Effects of Ball Milling and Extrusion Conditions... were fabricated via ball milling and spark plasma sintering(SPS), SPS followed by hot extrusion and powder extrusion. Two mixing conditions of CNF and aluminum powder were adopted: milling at 90 rpm......

of the sintered composites both increased with increasing the ball milling time. Key words: Ti35Nb2.5Sn/10HA; ultrafine grain; powder metallurgy; milling time 1 Introduction Recently β titanium alloys... 1) The α-Ti would transform into β-Ti completely after 12 h milling because of the mechanical alloying during the high energy ball milling. Nb and Sn solid diffuse into β-Ti to form Ti(Nb,Sn). 2......
2H); Trituration of micrograded tungsten carbide by high energy ball milling Abstract: The ultrafine tungsten carbide was prepared directly from micrograded raw products by high energy ball milling. The average particle size reaches its minimum at 0.4 μm after milling for 80 h, while the crystallite size reaches 10 nm. It means the as prepared WC particles......
