Deformation and Grain Growth of Low-Temperature-Sintered High-Purity Alumina
9 = 0.6 I / s ' 7 = 6.0 0 7 = 2 4 i ti 3 = 6 0 Through close control over green-state powder processing, pure alumina ceramics of 0.5-pm grain size were obtained by sintering at 1250°C. The static grain growth of this material was modest at temperatures below 1300°C. However, dynamic grain growth occurred rapidly during superplastic deformation. Therefore, although the ultrafine-grained alumina...
متن کاملHigh Temperature Erosion- Oxidation Behavior of Nickel- Based Alloys Containing Mo in Fluidized Bed Waste Incineration
High-temperature erosion-oxidation behavior of nickel-based alloys containing 0-7 wt.% Mo in fluidized bed waste incineration conditions was studied. A stream of hot condensed air with a flow rate of 25 L/min caused hot silica sand (700 °C) mixed with 0.5 wt.% of chloride salts to hit the specimens for 250 h. By removing the erosive factor, the high-temperature oxidation behavior of the alloys ...
متن کاملMo-Si-B alloys for ultrahigh-temperature structural applications.
A continuing quest in science is the development of materials capable of operating structurally at ever-increasing temperatures. Indeed, the development of gas-turbine engines for aircraft/aerospace, which has had a seminal impact on our ability to travel, has been controlled by the availability of materials capable of withstanding the higher-temperature hostile environments encountered in thes...
متن کاملDetermining the Hot Deformation Temperature Range of Medium Carbon Ni-Cr-Mo Low Alloy Steels using Hot Tensile and Hot Torsion Tests
The aim of this study was to investigate the suitable temperature range for hot deformation of three medium carbon Ni-Cr-Mo low alloy steels by hot tensile and hot torsion tests. Hot tensile tests were carried out in the te,prature range of 850-1150°C at a constant strain rate of 0.1 s-1 until fracture. Then, the tensile flow behavior, hot ductility and microstructural evolution of the steels w...
متن کاملOptimizaton of Mo-Si-B Intermetallic Alloys
Mo-Si-B intermetallics consisting of the phases Mo3Si and Mo5SiB2, and a molybdenum solid solution (“ -Mo”), have melting points on the order of 2000 °C. These alloys have potential as oxidationresistant ultra-high-temperature structural materials. They can be designed with microstructures containing either individual -Mo particles or a continuous -Mo phase. A compilation of existing data shows...
