Productivity‐Driven Optimization of Laser Powder Bed Fusion Parameters for IN718 Superalloy: Process Control, Microstructure, and Mechanical Properties

Advanced Engineering Materials, EarlyView.
This study demonstrates how optimizing laser power, scanning speed, and hatching distance in laser powder bed fusion can boost the productivity of Inconel 718 manufacturing by up to 29% while maintaining mechanical integrity. The work delivers a validated process window and cost–time analysis, offering industry‐ready guidelines for efficient additive ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Leptophilic ALPs in laboratory experiments

Journal of High Energy Physics
We study the collider phenomenology of leptophilic axion-like particles (ALPs), i.e. pseudoscalar particles that couple only to charged leptons. Loops of charged leptons induce effective interactions of the ALPs with photons, which depend on the momenta ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Boosting long lived particles searches at μTRISTAN

Journal of High Energy Physics
We study the prospects of the proposed μTRISTAN experiment, running in the energy asymmetric μ + e − mode, in probing long lived particles (LLPs) arising from the decay of the Standard Model Higgs boson. We focus on the proposed runs with E μ + E e − $$ \

An effective up quark mass from new light particles

Physics Letters B, 1991
Abstract I consider a model where an effective current mass for the up quark is provided by the interactions of a new neutral light colored scalar and a charge 1 3 colorless fermion. The model has no strong CP problem. A new confining U (1) prevents the occurence of physical states with fractional charges.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Are the new particles heavy or light in

In this work, we study the $$B^+\rightarrow K^+ E_{\textrm{miss}}$$, $$B^0\rightarrow K^{*0} E_{\textrm{miss}}$$, and $$\Lambda _b^0\rightarrow \Lambda ^0 E_{\textrm{miss}}$$ decays under three different new physics hypotheses: the heavy new particles ...
