Effects of Heating Rate and Temperature Holding Time on Mechanical Behaviors of Aluminum Alloy

Abstract:

In this paper, the mechanical properties of several aluminum alloys are obtained experimentally at different temperatures, from room temperature to about 4000C by using the Gleeble 1500 thermomechanical system. Besides, the thermal softening characteristics, effects of heating rate and temperature holding time are discussed in details. It is found that the strength of LF6, a kind of antirust aluminum alloy, is not sensitive to the heating rate (0.1-1000K/s) and temperature holding time (0-1h). However, the mechanical behaviors of other alloys depend on these factors very obviously. At last, these phenomena are discussed in the viewpoint of the microstructures and techniques of ageing strengthening of these alloys.
