Investigation on Aging Behavior of AZ91D Magnesium Alloy

Abstract:

Article Preview

The aging hardening curve of AZ91D magnesium alloy was gained, and aging behavior of the alloy was investigated with Vickers hardness measurement, differential scanning calorimetry (DSC), transmission electron microscope (TEM) after solution treated at 415°C for 10h , and water quenched at room temperature , afterwards aged at 175°C for 0-38h with a 2h interval. The result show that there are three aging peaks at aging hardening curve of AZ91D magnesium alloy, and that four types of β-Mg17Al12 precipitates were responsible for the aging peaks.
