Effect of Equal-Channel Angular Pressing and Subsequent Aging on the Structure and Mechanical Properties of Al–Mg2Si Alloys with Transition Metal Additions
The effect of equal-channel angular pressing (ECAP) at 150°C and subsequent aging on the structure and strength characteristics of Al–Mg2Si alloys with scandium and joint (Sc + Zr) and (Sc + Hf) additions is studied. Hardness and electrical resistivity curves demonstrate the decomposition of the supersaturated solid solution in the alloys with (Sc + Zr) and (Sc + Hf) additions is found to be same, and the optimum aging conditions of the alloys are obtained. The microstructure of the alloys and precipitation of secondary phases are studied in detail using scanning and transmission electron microscopy (SEM and TEM, respectively). The alloys subjected to ECAP and aging demonstrate an increase in the strength and the plasticity due to compensation of aging processes by recovery processes related to restructuring a dislocation structure.
期刊介绍:
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
