Effect of interpass temperature on the formation of retained austenite in a wire arc additive manufactured ER420 martensitic stainless steel
Materials Chemistry and Physics, 2021•Elsevier
In this study, thin-wall components of ER420 martensitic stainless steel were fabricated
through wire arc additive manufacturing (WAAM) at two different interpass temperatures of
25° C and 200° C. The effects of thermal history on the formation, volume fraction, and
distribution of retained austenite were characterized by scanning electron microscopy,
electron backscattered diffraction, and X-ray diffraction analyses. It was concluded that the
higher interpass temperature of 200° C leads to the formation of a higher content of retained …

Abstract
In this study, thin-wall components of ER420 martensitic stainless steel were fabricated through wire arc additive manufacturing (WAAM) at two different interpass temperatures of 25 °C and 200 °C. The effects of thermal history on the formation, volume fraction, and distribution of retained austenite were characterized by scanning electron microscopy, electron backscattered diffraction, and X-ray diffraction analyses. It was concluded that the higher interpass temperature of 200 °C leads to the formation of a higher content of retained austenite resulted from in-situ quenching and partitioning heat treatment during the fabrication process.
