dc.description.abstractThe effect of stress and temperature on the creep behavior of an Al-2.0wt%.Li alloy was investigated in the temperature range from 300 to 5000C. This temperature interval corresponds to a solid solution of Li in Al. Experimental results indicate that Al-2.0wt%Li behaves as a pure metal class alloy (class II). This is demonstrated by several creep characteristics including the value of the stress exponent (n - 5), the shape of the creep curve, and the nature of the creep transient after a temperature change. However, anomalous behavior of the activation energy was observed. Activation energies up to 55 kcal/mole, decreasing to approximately 33 kcal/mole at higher temperatures, were observed by the temperature cycling technique.
