چکیده مقاله
Severe plastic deformation SPD techniques are increasing their importance in the manufacturing of ultrafine grain structures of metallic alloys Among them, simple shear extrusion SSE is an emerging technique that outperforms other SPD techniques for its more uniform strain distribution and low product waste In the present study, the microstructure and mechanical properties of aluminum 2024 alloy processed by simple shear extrusion are studied Along with performing SPD techniques on the sample, two heat treatment operations including annealing and quenching are applied based on a given schedule Results show that the strength and hardness properties of the aluminum alloy after annealing, i e Anneal SSE and Anneal SSE Quench are improved by about 34% and 53%, respectively On the other hand, it is found that the impact energy is much reduced by performing this procedure The hardness of the specimen subjected to SSE is highly improved; also, the hardness increases by the increase in pass number
