Abstract Scope |
This presentation will discuss the use of multiple rapid solidification processing (RSP) techniques for two different alloys within the AISI 240 spec for 316L to observe the effects of composition and rapid solidification rate on the solidification microstructure. The alloys have similar compositions, except the Ni concentration is either 10.5 wt% or 13.5 wt%. The three RSP techniques (two-piston splat quenching, gas atomization, and laser powder bed fusion) cover a wide range of cooling rates between 103 K/s – 107 K/s. A combination of optical microscopy, electron microscopy, quantitative x-ray spectroscopy, electron backscatter diffraction, and vibratory sample magnetometry is used to observe microstructural features such as phase content, cell size, and nano segregation.
