Monitoring Precipitation Kinetics in Heat Treatable Aluminium Alloys Using In Situ Resistivity in Gleeble Thermomechanical Simulator

Abstract:

A conventional way to determine precipitation kinetics in heat treatable aluminium alloys is to monitor the associated solute loss by in-situ resistivity. A Gleeble machine is used to perform so called isothermal quenching (IQ) resistivity measurements. IQ consists in quenching the alloy down to a given temperature and holding it at this temperature. The results are validated against measurements performed with a classical four-points method using continuous current on the same alloy.
