- OS1910 Strain-rate history of aluminum
抄録
High-speed and quasi-static compression tests were conducted using short cylinder of pure aluminum A1050-0. The objective is to examine the effect of strain-rate history on the deformation behavior. The order of strain-rate was around 10^3 /s in high-speed or 10^<-2> /s in low-speed. The yield stress increased when the strain-rate changed from low-speed to high. The stress increased after the strain-rate change was more rapid comparing the slope where the bar was compressed under the low-speed condition only. On the other, the yield stress decreased in the case where the strain-rate changed from high-speed to low. The slope in stress-strain curve after the strain-rate change was steeper, in comparison with the result by low-speed compressive operation only. Further, the 3-step compressive operation was performed, where the specimen was compressed under high - low - high or low - high - low speed condition. Similarly, the positive effect in strain-rate history appeared.
