Quench factor analysis: step-by-step procedures for experimental determination

摘要

There have been a number of procedures reported for the prediction of physical properties of aluminum based on cooling rate data. One of the most common is the cooling rate calculation procedure described by Fink and willey in their now-classic work on 7075 characterization. Staley has more recently described the use of "Quench Factor Analysis" (QFA) to better predict various properties of aluminum which is the subject of this paper. A discussion of the principles of the calculation and the experimental procedure used for QFA determination from cooling curve data will be provided here. The generation of the multiparametric C_T function from cooling curves will also be discussed.
