A comparative study of flow instability criteria in the processing map of AlFeCoNiMo0.2 high-entropy alloys
ABSTRACT High-entropy alloys (HEAs) were studied via hot compression experiments using a Gleeble-3800 thermal simulation tester. The hot deformation behaviour of an AlFeCoNiMo0.2 HEA and the physical significance of the associated parameters were analyzed according to the Prasad, Gegel, Malas, and Murty instability criteria. Processing maps of different instability criteria under different conditions were constructed. The domain corresponding to a temperature range of 1070°C–1150°C with a strain rate range of 0.001–0.1 s−1 and average power dissipation rates of >40% did not feature flow instability; thus, this domain is appropriate for the AlFeCoNiMo0.2 HEA deformation process. Through microstructure analysis, it was determined that the deformation mechanism in the optimal forming region is dynamic recrystallization.
期刊介绍:
Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate.
Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
