Abstract: | Deformation of AMg6 alloy by tension under conditions of soft mode of loading is accompaniedbyjumplike deformation, which is registered graphically in the form of "steps" on the stress-strain curve. Jump-likedeformation also occurs under creep conditions after reaching a certain stress level on the stress-straincurve. There was studied the stress-strain curve of AMg6 alloy under quasi-static tension under soft loadingconditions, which revealed the changes in the material microstructure, and there were proposed themodelsestablishing a connection between them. The same studies were also concerned with the processes of creepand dynamic creep of AMg6 alloy. The microstructure analysis showed that after the creep tests intheAMg6alloy there were the destroyed dispersoids, as well as the solid ones. It was assumed that the process of jumplike creep, like jump-like tensile strain, is caused by the dispersoids cracking in the material. The techniquefor predicting the initiation of jump-like creep depending on the proportion of destroyed inclusionswasproposed. |
