For the aged aluminum alloys which generally contain disc/plate-shaped or rod/needle-shaped precipitates, a model has been established, from the viewpoints of thermodynamics, kinetics and strengthening theory, to relate quantitatively the yield strength to the size, volume fraction and aspect ratio of precipitates which all were analytical associated with the chemical compositions of alloys, aging temperature and aging time. This model has been experimentally proved to well predict the variation of yield strength with the evolution of disc/plate-shaped or rod/needle-shaped precipitates for present Al-4. 62wt% Cu-0.65wt% Mg alloy aged at 513K and Al-1. 12wt% Mg0.57wt% Si alloy aged at 463K, respectively, and the yield strengths simulated by this model were also found to be in well agreement with previously measured values for a series of aged Al-Cu binary alloys, AA6061 and Al-Zn-Mg alloys.

This thesis examines the antecedents of the voluntary behavior of retired teachers in the context of an integrated behavioral model that incorporates a wide variety of important factors from previous researches on volunteer behavior into a single theoretical framework provided by the Theory of Planned Behavior. The model was tested using data from a sample of 219 individual respondents by Structural Equation Model. Moreover, four voluntary teachers and six school administrators were interviewed to thoroughly explore factors affecting the success of the "Voluntary Teaching Program" in Taipei County.
