Aluminium Alloys Measurement in Quenching Dilatometer and Application of the Data

Abstract:

Thermal expansion is an important material property. From change of this quantity phase transformations can be evaluated. Therefore dilatometry is a common tool for construction of transformation diagrams in steel and prediction of material structure according to the performed heat treatment. However there are some restrictions for quenching dilatometers, such as magnetic properties of the material or weldability of the controlling and measuring thermocouple. In this article the quenching dilatometry is proposed for evaluation of precipitation during continuous cooling from solution annealing temperature. Aluminium alloy EN AW 6082 was chosen as the experimental material. Due to poor weldability of the experimental material new sample geometry was introduced.
