Abstract Scope |
Wire arc additive manufacturing (WAAM) is a promising technology in the production of large-scale functionally graded material components with high efficiency and relatively low cost. In the present study, a high-strength low alloy (HSLA) steel-Si-bronze-aluminum functionally graded material is manufactured, where Si-bronze will be sandwiched between HSLA steel and AA5456 aluminum alloy. The WAAM-ed functionally graded product combines the high strength and hardness of HSLA steels with the lightweight and toughness of aluminum. Si-bronze sandwiched layers provide the proper mechanical property transition and enhanced diffusion and hence the integrity of the processed functionally graded blocks. A parametric study for the deposition parameters is conducted to mitigate the thermal mismatch of multi-materials built layers aiming for minimizing the thermal stresses produced during processing. Mechanical and microstructural evolution of the built blocks, especially within the fusion zone between the dissimilar alloys are investigated. |
