Ablation with ultrashort laser pulses as a surface micromachining tool was studied using a
hybrid die-excimer laser system that has high energy per laser pulse (tens of mJ's), about …

Abstract Aging hardened Al-4.0 wt pct Cu alloy sheets with thicknesses (t) of 0.15 to 1.0 mm
were selected to explore the effects of the second phase and its interaction with the …

Micro-alloying technology is widely used in the development of high-performance Al–Cu
alloys for high-temperature applications. This study investigated Al–6 wt.% Cu alloys …

the direction of Dr. Mohammed Page 1 ABSTRACT CHEN, MUH-JANG. Defect Evolution and …

A coherent precipitate formed in a metallic alloy is of importance in its strengthening
mechanism, owing to dislocation/precipitate interaction. Therefore, the present study …

The main tenets of dislocation theory assume that dislocation behavior in the crystal
structure is statistically Gaussian and can be accurately determined by taking the average …

The synergistic effects of Er and Sc on the aging behavior and θ'precipitation stability of Al-
Cu alloys were systematically investigated. The combination of Er and Sc plays an important …

El endurecimiento por precipitación es uno de los mecanismos de refuerzo más eficaces
para aumentar el límite elástico de las aleaciones metálicas. La presencia de una …

Abstract Combination of High Angle Annular Dark Field-Scanning Transmission electron
microscopy (HAADF-STEM) images and STEM-EDX elemental mapping were used to …

The effects of anisotropic interfacial properties and heterogeneous elasticity on the growth
and ripening of plate-like θ′-phase (Al2Cu) in Al-1.69 at.% Cu alloy are studied. Multi …
