, China) 摘要:Modified 6005A alloy was reported and its mechanical properties were studied by tensile test, hardness measurement and TEM analysis. Results show that the favorable aging condition for 6005A is 175℃ for 8h, and the nose temperature of its TTP (Time-temperature-properties) curves is about 370℃. In a moderate temperature zone (270℃＜T＜390℃), the alloy has much high quench sensitivity......

for 1 h, the specimens were subjected to end quenching test, room temperature (RT) water quenching and boiling water quenching to obtain different quenching rates. Thermocouples were inserted into the specimens to record time-temperature data to estimate quenching rate. End quenching test led to quenching rates from 2 °C/s to 11 °C/s through the critical temperature range of 415-185 °C......
