Journal ArticleDOI
The effect of laser focus shift on microstructural variation of Inconel 718 produced by selective laser melting
Tait D. McLouth,Tait D. McLouth,Glenn E. Bean,David B. Witkin,Scott D. Sitzman,Paul M. Adams,Dhruv N. Patel,Woonsup Park,Jenn-Ming Yang,Rafael J. Zaldivar +9 more
TL;DR: In this paper, the laser focal shift was used for tailoring the microstructures of parts made by SLM, and the results showed that parts manufactured at different focal positions had finer microstructure than those manufactured away from it.
Journal ArticleDOI
Build Orientation Effects on Texture and Mechanical Properties of Selective Laser Melting Inconel 718
Glenn E. Bean,Tait D. McLouth,David B. Witkin,Scott D. Sitzman,Paul M. Adams,Rafael J. Zaldivar +5 more
TL;DR: In this article, the variation in tensile properties of Inconel 718 at varying angles with respect to build direction was investigated, and it was found that a preferred grain texture and twinning orientation that aligns with the build direction may contribute to the anisotropic enhancement in ductility.
Journal ArticleDOI
Variations in ambient and elevated temperature mechanical behavior of IN718 manufactured by selective laser melting via process parameter control
Tait D. McLouth,Tait D. McLouth,David B. Witkin,Glenn E. Bean,Scott D. Sitzman,Paul M. Adams,Julian R. Lohser,Jenn-Ming Yang,Rafael J. Zaldivar +8 more
TL;DR: In this paper, the effects of process parameters on the microstructural development and mechanical properties of SLM Inconel 718 were investigated using a continuous scanning strategy in conjunction with changes in laser spot size.
