been established that α and ω phase precipitates appear depending on aging temperature and time in hardenable (α+β) or metastable β alloys [5-6]. The homogeneous nucleation and subsequent growth... β grain structure is obtained but grain growth is significant. The average grain size is about 180 mm. The heat treatment was then followed by aging at 300-650 ℃ for different time. Fig.1 Optical......
at comparatively low aging temperatures and the aging time reaches the peak value usually after 10 h[10]. After 2 h, a stable stage of hardness can be observed for the specimens aged at 500 and 570 ℃. However...

response of extruded specimens is quick and marked when the samples are aged at 200 to 250 ℃ for different time, and the peak aging hardness is about HV120. The tensile strengths at 25, 200, 250 and 300... at three ageing temperatures, the peak aging hardness at 200 ℃ is the highest, but the time to peak-aging is the longest, the aging curve at 250 ℃ indicates that the effectiveness at 250 ℃ is not as good......

temperature increases, the creep strain increases from 0.018% at 143 °C to 0.058% at 153 °C, and then to 0.094% at 163 °C. Within 25 h aging, the number of creep steps increases and the duration time...(a) shows the creep strain of Al-Li-S4 aluminum alloy as a function of aging time under the same stress and different temperature. The creep strain of the material rises significantly......
