Mechanical Properties of a Heat-Treatable Al-Sc Alloy Reinforced with Al2O3 Dispersoids
The mechanical behavior of precipitation-strengthened Al-0.18 wt.% Sc alloys containing 30 vol.% Al2O3 dispersoids is studied at 25, 300 and 350°C. The effect of Al3Sc precipitate size is studied by varying aging treatments. Microhardness measurements show that both populations of particles (nanometer-sized Al3Sc precipitates and submicron-sized Al2O3 dispersoids) contribute to strength at ambi...
متن کاملMechanical Properties of Magnesium-Rare Earth Alloy Systems: A Review
Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the...
متن کاملSome Mechanical Properties of DTD 5025 Magnesium Alloy Castings 4 ’
SUMMARY This Report describes an investigation into the tensile and torsional properties of DTD 5025 magnesium alloy castings. Strength and stiffness values are given, and the variation of these parameters between different batches and manufacturers is shown. The effect on mechanical properties of long and short term temperature environments is mdwated.
متن کاملMicrostructure and mechanical properties of magnesium containing high volume fractions of yttria dispersoids
This paper examines the room-temperature microstructure and mechanical properties of dispersion-strengthened-cast magnesium (DSC-Mg) containing 30 vol.% of 0.33 mm yttria dispersoids. The dispersoids are reasonably well distributed in both cast and extruded materials and the extruded matrix grains size is about 0.88 mm, in agreement with existing models on grain pinning. The Young’s modulus mea...
متن کاملGrain Refinement and Enhancement of Mechanical Properties of Hot Extruded Rare-Earth Containing Magnesium Alloy
The effects of rare earth addition and hot extrusion process on the grain refinement of magnesium alloy were studied. The as-cast Mg-6Al-1Zn (AZ61) alloy had the average grain size of ~ 64 µm and its microstructure consisted of α-Mg and Mg17Al12 phase. By partial substitution of Al with Gd to reach Mg-4.8Gd-1.2Al-1Zn alloy, it was observed that the Mg17Al12 phase disappeared and two new interme...
