Direct Natural and Artificial Aging of Aluminum Alloy AlSi10Mg After Laser Powder‐Bed Fusion

Advanced Engineering Materials, EarlyView.
Laser powder‐bed fusion of metals aluminum alloy AlSi10Mg has been directly aged. Artificial aging after natural aging is considered. The hardening potential is high for the top part of the samples as well as after short natural aging. The hardening potential is substantially reduced for the bottom part of the samples, as well as after natural aging of

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti‐6Al‐4V

Advanced Functional Materials, EarlyView.
This research applies advanced laser beam shaping (LCoS‐SLM) to fabricate the Ti‐6Al‐4V alloy via laser powder bed fusion. A tailored beam is used to prevent martensite formation and create a dual α+β microstructure by controlling cooling rates.

Relations between Rockwell Hardness and Vickers Hardness in Engineering Ceramics

Journal of the Ceramic Association, Japan, 1986
Rockwell and Vickers hardnesses of silicon nitride, silicon carbide and partially stabilized zirconia were determined. Rockwell superficial hardness decreased linearly when the load increased. A table of the relation between Rockwell hardness and Vickers hardness for high strength ceramics has been obtained by comparing Vickers hardness with Rockwell ...

Xolography for Rapid Volumetric Production of Objects from the Nanoscopic to Macroscopic Length Scales

Advanced Materials, EarlyView.
This article explores the development of materials with multi‐scale control at the nanoscale (<100 nm), micrometer‐scale (80 µm), and macro‐scale (multi‐component geometries). This is achieved by applying polymerization‐induced microphase separation (PIMS) process via volumetric 3D printing (Xolography), expanding the design space for functional ...
