Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

Advanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

Advanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Modern Tests of Special Relativity

Physics Today, 1987
From our perspective one hundred years after the fact, the null result of the Michelson-Morley ether-drift experiment clearly marked the beginning of the end for the Newtonian notions of absolute space and time. At the time, however, it took 20 years of work by H. A. Lorentz, Henri Poincaré and others for most physicists to come to the same conclusion.

Tests of Special Relativity

2017
With the mass-energy \(m=E(v=0)/c^{2}\) relation, all pivotal properties of special relativity have been now derived and we consider the related status of SR tests. 1) There are direct tests exploring i) the speed of light in different context, ii) the time dilation, iii) the body contraction, and iv) mass-energy relation.
