during semi-solid isothermal heat treatment were investigated deeply in the present work. Results showed that the lamellar (Mg,Al)3Gd phases transformed into the particle-like Al2Gd phases in AZ31 magnesium alloys with Gd addition during semi-solid isothermal heat treatment, leading to yielding more spherical α-Mg grains. When Gd content is 2.0 wt. %, the size of semi-solid spherical grains......
for nanocomposites. T6 heat treatment (solid solution at 530 °C for 2 h and aging at 175 °C for 6.5 h in this work) is also considered an effective method to strengthen nanocomposites [15-17]. CASATI et al [16... samples were rolled at 500 °C with a speed of 20 mm/s, from 3 mm to 1.5 mm in three passes. Lastly, a solid solution treatment at 530 °C for 2 h and aging at 175 °C for 6.5 h, named T6 heat treatment, were......
of ZL114A alloy by adjusting heat treatment process is one of the high spots. Optimum heat treatment process is determined by adjusting the solution temperature[4-5], solution time[4-6], quenchant[4... of ZL114A alloy plate used in the present experiment. Six heat treatment processes were designed for evaluation, as listed in Table 2. Salt solution treatment was employed in molten salt, in which......
