Journal ArticleDOI
Hot isostatic pressing of IN718 components manufactured by selective laser melting
TL;DR: In this article, the influence of the HIP process parameters on the density and microstructure of IN718 SLM components is investigated by means of micro X-ray computed tomography and scanning electron microscopy.
Journal ArticleDOI
On the microstructural and mechanical properties of post-treated additively manufactured Inconel 718 superalloy under quasi-static and cyclic loading
M.E. Aydinöz,Florian Brenne,Mirko Schaper,C. Schaak,Wolfgang Tillmann,Jens Nellesen,Thomas Niendorf +6 more
TL;DR: Inconel 718 specimens were additively manufactured via selective laser melting (SLM) and subjected to different post-process heat treatments as discussed by the authors, and HIP was employed in order to reduce the porosity typically present after SLM.
Journal ArticleDOI
An investigation of the blanking process of the quenchable boron alloyed steel 22MnB5 before and after hot stamping process
TL;DR: In this article, the authors developed economical shearing methods for use on the press hardened ultra high strength steels which will enhance the tool life and meanwhile to achieve good product quality.
Journal ArticleDOI
Duplex stainless steel fabricated by selective laser melting - Microstructural and mechanical properties
Florian Hengsbach,Peter Koppa,Kristina Duschik,Martin Holzweissig,Madison Burns,Jens Nellesen,Wolfgang Tillmann,Thomas Tröster,Kay-Peter Hoyer,Mirko Schaper +9 more
TL;DR: In this paper, microstructural and mechanical characterizations of duplex stainless steel UNS S31803 processed by selective laser melting (SLM) are conducted to shed light on the phase arrangement evolving in the as-built condition and in several heat-treated conditions.
Journal ArticleDOI
Microstructural Characterization and Mechanical Performance of Hot Work Tool Steel Processed by Selective Laser Melting
TL;DR: In this article, the microstructure after layer-wise processing partially consists of metastable-retained austenite which transforms to martensite in a subsequent tensile test.
