The grain size dependence of the yield stress of an Al-Al4Ca alloy with microduplex structure is investigated. A model for its interpretation is proposed in which the critical mechanism for the occurrence of macroscopic yielding is the nucleation of dislocations at the Al/Al4Ca interfaces. The ...

Hardness tests are very convenient to use because of the small scale size of the actual test. Mechanically alloyed (MA) alloys appear to be ideal candidates from which yield stress can be determined from hardness measurements. The yield stress of MA aluminum alloys can be represented by an ...

The undercooled supersaturated aluminium alloy EN AW-6082 has been investigated during in-situ quenching experiments by means of differential scanning calorimetry and thermomechanical analysis. Calorimetry resulted in continuous time-temperature-precipitation diagrams and thermomechanical analysis in stress/strain...
