Physics-based thermal-chemical-fluid-microstructure modelling of in-situ alloying using additive manufacturing: composition-microstructure control

Abstract:

Nucleation and grain growth during metal additive manufacturing (AM) still remain debatable since the nature of rapid melting and solidification induced by laser-powder interaction during AM may cause particular liquid metal behaviour especially when in-situ alloying is used. The rationalisation of the role of heterogeneous mixing in the microstructure development is of importance for composition control and hence process optimisation. In this work, coupled thermal-chemical-fluid-microstructu...
