Warm-temperature tensile ductility in Al-Mg alloys
Abstract Several binary and ternary Al alloys containing from 2.8 to 5.5 wt pct Mg were tested in tension at elevated temperatures (200 °C to 500 °C) over a range of strain rates ($ 10^{−4} $ to 2.0 $ s^{−1} $). Tensile ductilies of up to 325 pct were obtained in binary Al-Mg alloys with coarse grai...

| 520 | |a Abstract Several binary and ternary Al alloys containing from 2.8 to 5.5 wt pct Mg were tested in tension at elevated temperatures (200 °C to 500 °C) over a range of strain rates ($ 10^{−4} $ to 2.0 $ s^{−1} $). Tensile ductilies of up to 325 pct were obtained in binary Al-Mg alloys with coarse grains deformed in the solute-drag creep regime. Under test conditions in which solute-drag creep controls deformation, Mg in concentrations from 2.8 to 5.5 wt pct neither affects tensile ductility nor influences strain-rate sensitivity or flow stress significantly. Strength is shown to increase with increasing Mg concentration, however, in the power-law-breakdown regime. The solute-drag creep process, which leads to superplastic-like elongations, is shown to have no observable grain-size dependence in a binary Al-Mg material. Ternary alloying additions of Mn and Zr are shown to decrease the strain-rate sensitivity during solute-drag creep, negatively influencing ductility. An important cause of reduced ductility in the ternary alloys during creep deformation is found to be a transition from necking-controlled failure in the binary alloys to cavitation-controlled failure in the ternary alloys investigated. An increase in ternary element concentration, which can increase the relative volume percentage of proeutectic products, increases cavitation. | ||

Warm-temperature tensile ductility in Al-Mg alloys |
| abstract |
Abstract Several binary and ternary Al alloys containing from 2.8 to 5.5 wt pct Mg were tested in tension at elevated temperatures (200 °C to 500 °C) over a range of strain rates ($ 10^{−4} $ to 2.0 $ s^{−1} $). Tensile ductilies of up to 325 pct were obtained in binary Al-Mg alloys with coarse grains deformed in the solute-drag creep regime. Under test conditions in which solute-drag creep controls deformation, Mg in concentrations from 2.8 to 5.5 wt pct neither affects tensile ductility nor influences strain-rate sensitivity or flow stress significantly. Strength is shown to increase with increasing Mg concentration, however, in the power-law-breakdown regime. The solute-drag creep process, which leads to superplastic-like elongations, is shown to have no observable grain-size dependence in a binary Al-Mg material. Ternary alloying additions of Mn and Zr are shown to decrease the strain-rate sensitivity during solute-drag creep, negatively influencing ductility. An important cause of reduced ductility in the ternary alloys during creep deformation is found to be a transition from necking-controlled failure in the binary alloys to cavitation-controlled failure in the ternary alloys investigated. An increase in ternary element concentration, which can increase the relative volume percentage of proeutectic products, increases cavitation. © ASM International & TMS-The Minerals, Metals and Materials Society 1998 |

An important cause of reduced ductility in the ternary alloys during creep deformation is found to be a transition from necking-controlled failure in the binary alloys to cavitation-controlled failure in the ternary alloys investigated. An increase in ternary element concentration, which can increase the relative volume percentage of proeutectic products, increases cavitation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cavitation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Material Transaction</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Tensile Ductility</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ternary Addition</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Binary Material</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Henshall, Gregory A.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nieh, T.
