Additively manufactured hierarchical stainless steels with high strength and ductility.
Many traditional approaches for strengthening steels typically come at the expense of useful ductility, a dilemma known as strength-ductility trade-off. New metallurgical processing might offer the possibility of overcoming this. Here we report that austenitic 316L stainless steels additively manufactured via a laser powder-bed-fusion technique exhibit a combination of yield strength and tensil...
متن کاملMagnetic Field Induced Phase Transitions in YBa2Cu4O8
The c-axis resistivity measurements in YBa2Cu4O8 from Hussey et al. for magnetic field orientations along the c-axis as well as within the ab-plane are analyzed and interpreted using the scaling theory for static and dynamic classical critical phenomena. We identify a superconductor to normal conductor transition for both field orientations as well as a normal conductor to insulator transition ...
متن کاملQuantitative Neutron Dark-field Imaging through Spin-Echo Interferometry
Neutron dark-field imaging constitutes a seminal progress in the field of neutron imaging as it combines real space resolution capability with information provided by one of the most significant neutron scattering techniques, namely small angle scattering. The success of structural characterizations bridging the gap between macroscopic and microscopic features has been enabled by the introducti...
متن کاملAdditively Manufactured Porous Biomaterials and Implants
Recent advances in additive manufacturing (AM) techniques (otherwise known as 3D printing) have enabled fabrication of a new class of porous biomaterials (Figure 1) with arbitrarily complex and precisely controlled topologies that e.g. resemble the geometry and micro-architecture of (trabecular) bone. Since the geometry of scaffolds and biomaterials is an important factor in bone tissue regener...
متن کاملAnalysis of Porosity in Additively Manufactured Parts using 3D Metallographic Analysis Compared to Conventional 2D Stereology Estimates
Porosity is a typical defect in additively manufactured (AM) parts. Such defects limit the properties and performance of AM parts, and need to be characterized accurately. Current methods for characterization using microstructure rely on classical stereological methods that extrapolate information from two dimensional images. Newer three dimensional (3D) microstructural analysis techniques prov...
