	High-temperature fatigue of Ni-based single crystal superalloys is studied at 1000 \&deg;C in a wide range of loading conditions (\&minus;1 ? R ? 0.8) and number of cycles (103 \&minus; 109). Under fully reversed conditions, a competition between crack initiations from the surface\&mdash; assisted by oxidation\&mdash;and from internal metallurgical defects\&mdash;mostly large casting pores\&mdash;is observed. Increasing the testing frequency shifts the competition to a higher number of cycles. Conversely, decreasing the casting pore size or coating the specimen promotes surface initiations. When a positive mean stress is added (R ? 0), a creep deformation/damage mechanism mainly controls fatigue life, despite fracture surfaces presenting a variety of initiation types. Fatigue life can be predicted by a simple creep law if the contribution of the alternating stress is considered. A linear damage summation method that considers pure fatigue and pure creep damage is used to predict the fatigue lives, and Haigh diagrams for different alloys are presented.

	Two phases dominate the performance of commercial Mg alloys: (1) \&beta; Mg17Al12 and (2) porosity. Alloy design and process design to optimize the morphology of the first and to minimize the second are discussed. Second phase \&beta; can be designed to improve tensile strength, fatigue strength, toughness, texture, formability and corrosion resistance of Mg alloys. Processing is applied to refine the grain size, to array this phase in micron sizes at grain boundaries, and to further precipitate this phase in nanometer arrays within the grains. Therein, the 2nd phase \&beta; plays the following roles: (1) retarding grain growth, (2) randomizing texture, (3) Hall\&ndash;Petch hardening, (4) Orowan hardening, and (5) moderating corrosion. Porosity is a detrimental 2nd phase common to cast Mg alloys in the form of gas or voids; its control being essential to engineering applications. Porosity can be diminished by sub-liquidus molding with high-velocity/high-pressure injection and then eliminated by subsequent hot deformation.
