J. Cent. South Univ. (2020) 27: 1168-1175 DOI: https://doi.org/10.1007/s11771-020-4357-3 Creep behavior and mechanical properties of Al-Li-S4 alloy at different aging temperatures ZHOU Chang(周畅)1... Abstract: Creep age forming techniques have been widely used in aerospace industries. In this study, we investigated the effect of aging temperature (143 °C-163 °C) on the creep behavior of Al-Li-S4......
magnetic resonance porosity enhancement. The constant load induces increasing rock plastic deformation, volume, and creep aging damage. As the loading stress increases, the instantaneous rock elastic...] proposed a rock brittle creep model based on aging damage, and revealed the law of microscopic crack propagation damage by numerical calculation. YANG et al [29] established an elastic and viscous......
