Previous studies of a single lot of NiAl powder which had been ground under high intensity conditions in liquid nitrogen (cryomilling) indicated that this processing leads to a high strength, elevated temperature NiAl–AlN composite. Because this was the first known example of the use of the reaction milling process to produce a high temperature composite, the reproducibility of this technique was unknown. Two additional lots of NiAl powder and a lot of a Zr-doped NiAl powder have been cryomilled, and analyses indicate that AlN was formed within a NiAl matrix in all three cases. Compression testing between 1200 K and 1400 K has shown that the deformation resistance of these heats is similar to that of the first lot of NiAl–AlN; thus cryomilling can improve the creep resistance of NiAl by a factor of six. Based on this work, it is concluded that cryomilling of NiAl powder to form high temperature, high strength NiAl–AlN composites is a reproducible process.

Large extrusion and forgings of Al-9Fe-1.9Mo-1.7Si (wt.%, FMS0918) aluminum alloy for elevated temperature applications were produced by rapidly solidified powder metallurgy process. Powders of FMS0918 alloy were produced by inert gas atomization, and then screened, canned, degassed, extruded and forged. The extrusion exhibited good strengths and elongation in longitudinal orientation, but low elongation in long- and short-transverse orientations. After forged, the tensile strengths of the forgings showed little change, but the long- and short-transverse elongation was improved.

Increasing Temperature

This paper presents the effects of elevated temperature on the mechanical response of a glass fibre reinforced epoxy (GFRE) composite. The mechanical properties taken into account are tensile, compression and shear. All tests are carried out at temperatures of 30°C, 70°C and 110°C, below the glass transition temperature of the resin. The properties along fibre direction and perpendicular to fibre direction are investigated, with two sets consisting of 0° and 90° fibre direction for tensile and compression tests. Stress-strain profiles at each temperature are firstly compared. Subsequently, the elastic modulus and the ultimate strength with respect to temperature are assessed. The results indicate that tensile properties remain relatively unaffected at 70°C but drop rapidly at 110°C. In addition, compressive properties decrease steadily from 30°C to 110°C, while shear properties are heavily degraded with increasing temperature. Fibre dominated properties have better heat resistance compared to matrix dominated properties due to matrix softening and weakening.
