Effect of Quenching Conditions

From (6)-(8), the transformad fraction for the SRO reaction via both nonoverlapping processes can be also expressed as, 

As pointed out before, -0 is a measure of the dominance of stage 1, which is, in turn, determined by thee quenching conditions, namely quenching temperature, quenching rate and specimen shape. Disc-shaped samples of Cu-19% A1 quenched from two different temperatures using a high quenching rate device

Abstract. The Thermal Analsysis (TA) applies a great variety of techniques suitable for determining the thermophysical properties of solids. Here after a wide and detailed review on more conventional methods of differential thermal analysis (DTA) and differential scanning calorimetry (DSC) to study non-equilibrated materials, the experimental results obtained from Short-Range Ordering (SRO) in a Cu-Al alloys is presented and discussed. The kinetic parameters and laws in these materials are deeply discussed focusing attention also to vacancy behavior and effects of quenching conditions.
