The effect of the third-element addition on the fatigue properties of mechanically alloyed Al–Ti alloys
TL;DR: In this article, the fatigue properties of MA Al-Ti alloys were examined at room temperature, 300°C and 400°C, and a decrease in fatigue strength was observed as the temperature was increased.

Evolution of microstructure and tensile strength of rapidly solidified Al-4.7 pct Zn-2.5 pct Mg-0.2 pct Zr-X wt pct Mn alloys
TL;DR: In this article, an analytical transmission electron microscopy and thermal analysis of as-extruded Al-4.7 pct Zn-2.5 pct Mg-0.2 pct X wt pct Mn alloys was carried out to elucidate the microstructural change and accompanying mechanical properties during subsequent heat treatments.
Journal ArticleDOI
Comparison of torsion and compression constitutive analyses for elevated temperature deformation of Al–Li–Cu–Mn alloy
TL;DR: The torsion and compression results were analysed using equation A(sinh ασ)n=Z=e exp(QHW/RT), where Z is the Zener- Hollomon parameter.

A finite element model of the effects of primary creep in an Al-SiC metal matrix composite
Steven L. Atkins,J. C. Gibeling +1 more
TL;DR: In this article, a two dimensional axisymmetric finite element model was developed to study the creep behavior of a high-temperature aluminum alloy matrix (alloy 8009) reinforced with 11 vol pct silicon carbide paniculate.

Damage Tolerance in Discontinuously Reinforced Metal-Matrix Composites
H. J. Rack,P. Ratnaparkhi +1 more
TL;DR: In this paper, the fatigue and fracture toughness behavior of particulate-reinforced MMCs can be described utilizing linear-elastic fracture mechanics, but the generalized use of this methodology for short fiber-based composites, where reinforcement orientation effects may be paramount, must be approached with caution.
