Influence of Preheating Temperature on the Microstructure and Mechanical Properties of 6061/TA1 Composite Plates Fabricated by AFSD

Abstract

In this study, composite plates of 6061/TA1 were successfully manufactured using additive friction stir deposition (AFSD). The impact of preheating temperatures (room temperature, 100 °C, 200 °C) on the interfacial microstructure and interface mechanical properties at various deposition zones was studied. The results showed that as the preheating temperature increased or when the deposit zone shifted from the boundary to the center, the diffusion width of Al and Ti increased, accompanied by an increase in bonding shear strength. Moreover, in the boundary zone of the sample preheated at room temperature (P-RT), only mechanical bonding was observed, resulting in the lowest bonding shear strength. Conversely, the other samples exhibited a combination of mechanical and metallurgical bonding. Under the preheating temperature of 200 °C, interfacial intermetallic compounds were observed near the center zone, which exhibited the highest bonding shear strength.

“…It is compatible with the publication of several review works about this issue (e.g. there exist different current review works that address different aspects of AM for metals) (Aboulkhair et al , 2019; Carolo and Cooper O., 2022; Gong et al , 2023; Kaur and Singh, 2019; Khorasani et al , 2023a, 2023b, 2023c; Orzolek et al , 2022; Slavkovic et al , 2023; Springer et al , 2023; Talignani et al , 2022; Volpato et al , 2022).…”

“…This issue has been highly developed in recent years and there are different current review works that address different aspects of AM for metals (C. B. Carolo and Cooper O., 2022; Gong et al , 2023; Orzolek et al , 2022; Slavkovic et al , 2023; Springer et al , 2023; Talignani et al , 2022; Volpato et al , 2022). Some work has already identified this SLM as the most important technology in earlier periods (Kabir et al , 2020).…”
