Abstract EN
A new master sintering curve (MSC) is proposed for Al-Mg alloy in order to effectively design the pressure-assisted sintering process.
In this work, hot pressing experiments of Al-Mg alloy powders are performed.
The changes of relative density during hot pressing are measured for the various heating rates of 5°C/min, 10°C/min, and 20°C/min at the fixed pressure of 50 MPa.
A work of sintering, designated as Θ, is introduced and defined as Θ(t,T)=∫0t1/Texp-Q/RTdt.
A work of sintering, Θ, could be interpreted as a measure for the amount of sintering work.
The MSC in this work defines the relation between the apparent density and a work of sintering, Θ.
Since the measurement of an apparent activation energy, Q, is very difficult, the correct value of Q is obtained numerically using a mean residual square method.
Then, the master sintering curves for sintering of Al-Mg alloy powders are proposed for the sintering temperatures of 400°C and 500°C through scaling procedures.
It is expected that the master sintering curves proposed in this work could help an engineer to design pressure-assisted sintering process for Al-Mg alloy.
