Study on microstructure, tensile, wear, and fracture behavior of A357 by modifying strontium (Sr) and calcium (Ca) content

Development of aluminium cast parts by stircasting technique is an effective method. Stircasting technique is one of the most commonly accepted techniques. In the present investigation, how the microstructure, mechanical and wear mechanics of A357 alloy were impacted by the presence of Sr/Ca was investigated. The outcomes revealed that addition of elements (Sr/Ca) enhance the microstructural features. Uniform dispersal of particulates (Sr/Ca) in A357 alloy and also the modified structure of silicon (Si) were observed. The outcomes also exhibited that, the simultaneous additions of Sr/Ca cause a considerable improvement of tensile strength and wear resistance. The study on fractured surfaces reveals the acceptable bonding among A357+Sr/Ca element.
