Abstract Scope |
The bending and uniaxial creep behavior of A205 aluminum alloy printed by laser powder bed fusion was studied in the temperature range of 150-200°C and stress range of 100-250 MPa. During bending creep testing, digital image correlation was employed for mapping the strains at different locations in the small size cantilevers. The stress and strain fields vary across the length and thickness of the cantilever beam, which facilitates in obtaining multiple stress-strain rate data points from a single test. The steady state creep rates obtained from the bending creep tests were well in line with those measured from conventional uniaxial creep tests performed at equivalent stress and temperature, which validated bending creep as a high throughput testing method. The intragranular nanoscale precipitates of Al-Cu (’) and Al-Cu-Ag-Mg () were responsible for excellent creep resistance and thermal stability, which makes A205 an attractive material for high temperature aerospace applications. |
