| Abstract Scope |
The combination of the design freedom offered by metal laser powder bed fusion (L-PBF) with multi-material capabilities offers the opportunity to fabricate new advanced components for a number of high value industries. In this talk, we investigate the deposition of CuSn10 with 316L using L-PBF technology equipped with a selective powder deposition recoater developed by Schaeffler Aerosint. Material characterisation of each deposition sequence was conducted to understand the microstructure, distribution of alloying elements, phase formation, and cracking behaviour at the interface. These observations are coupled with thermodynamic modelling of the melt pool at the interface to explain the phases which develop and the nature of the cracking. The results of this work indicate the importance of using thermodynamic calculations and appropriate laser scanning strategies to aid the selection of suitable alloy combinations. The knowledge gained from this work can be used to enable the production of functional bimetallic components. |
