Microhardness and Microstructure Analysis of the LPBF Additively Manufactured 18Ni300
MaterialsThis research focuses on analysing the 18Ni300 maraging steel produced through laser powder bed fusion. Specifically, it aims to examine the phase components using X-ray diffraction, the microstructure through scanning electron microscopy, and the hardness of the different structures present in the manufactured material.

A coalition is usually called stable if nobody has an immediate incentive to leave or to enter the coalition since he does not improve his payoff. This myopic behaviour does not consider further deviations which can take place after the first move. Chwe (

Advanced Science, Volume 13, Issue 21, 13 April 2026.Laser material processing is a promising technique for fabricating metal structures. Here, external electric field (EFs) assisted laser processing of metallic powders are investigated. EFs affect the melt tracks through changes in their stability and influence the grain structure in conjunction with laser intensity distribution methods. The EF‐assisted

A Graph-Traversing Algorithm for Computing Some Stable Sets in Effectiveness Coalitional Games [PDF]
We propose an algorithm for computing "main stable sets" recently introduced by Ciardiello, Di Liddo (2009) on effectiveness form coalitional games modeled through a directed pseudograph.

Advanced Science, Volume 13, Issue 20, 9 April 2026.A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.
