摘要：

In the present work, a Fe-Mn-Si shape memory alloy containing V and C has been fabricated by laser powder bed fusion for the first time. A pronounced pseudo-elasticity compared to a similar alloy but conventionally manufactured is achieved after aging treatment, as a result of the fine microstructure developed during the process and of the evaporation of Mn. The formation of high precipitate densities is also responsible for the improved thermo-mechanical properties. The size and density of precipitates significantly vary with aging conditions and account for important variation in material's performance. A maximum pseudo-elasticity is observed in samples aged at 750 ? for 6 h. The recovery strain upon unloading exceeds the values achieved in the conventionally manufactured alloy by more than 50%.(c) 2022 The Author(s). Published by Elsevier B.V.
