Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

On the local Langlands correspondence for non-tempered representations

, 2014
Let G be a reductive p-adic group. We study how a local Langlands correspondence for irreducible tempered G-representations can be extended to a local Langlands correspondence for all irreducible smooth representations of G.

Carbides Evolution and Tensile Property of 4Cr5MoSiV1 Die Steel with Rare Earth Addition

Metals, 2017
Studies of 4Cr5MoSiV1 die steel suggest that under appropriate conditions, additions of rare earth (RE) can enhance tensile property. This improvement is apparently due to the more uniform distribution of carbides and the enhancement of precipitation ...

Microstructural, Mechanical, and Textural Evolution of Dissimilar Combination of Laser‐Welded Maraging Steel and 4340 Steel

Advanced Engineering Materials, EarlyView.
The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

Relativistic Schrödinger equation and probability currents for free particles

Pracì Mìžnarodnogo Geometričnogo Centru
In this work, we start from the problem of quantizing the relativistic Hamiltonian of a free massive particle (rest mass different from 0), a problem exceptionally difficult in the standard approaches to quantum mechanics.

Characterization of regular tempered distributions [PDF]

Annales Polonici Mathematici, 1983
This paper gives an elementary proof of the following property: a locally Lebesgue integrable complex valued function u is a regular tempered distribution, i.e., \(u[\sigma]=\int u(x)\sigma (x)dx\) for \(\sigma \in S\) (with \(u\sigma\in L_ 1)\) iff for a certain non-negative integer k the function \(R^ n\ni x\mapsto u(x)/(1+| x|^ 2)^ k\) is integrable

Influence of Fe Particle Size Distribution on Chemical Homogeneity, Microstructure, and Crack Formation in Fe–SiC Powder Blends Processed by PBF‐LB/M

Advanced Engineering Materials, EarlyView.
The influence of Fe particle size on in situ alloying of Fe–SiC powder blends in PBF‐LB/M is revealed. Contrary to expectations, the coarser Fe fraction provides a broader crack‐free processing window and slightly improved elemental homogeneity while producing higher but more variable hardness. The results highlight a complex trade‐off between particle

Well-Tempered Variational Approach to Enhanced Sampling

, 2015
We propose a simple yet effective iterative scheme that allows us to employ the well-tempered distribution as a target distribution for the collective variables in our recently introduced variational approach to enhanced sampling and free energy ...

A Tempered Fractional Kinetic Transport Theory for Energetic Particle Interaction with Quasi-two-dimensional Turbulence in the Large-scale Solar Wind

The Astrophysical Journal
Observational evidence is accumulating that turbulence in the solar wind is intermittent (non-Gaussian) because of the strong presence of a quasi-two-dimensional (quasi-2D), low-frequency turbulence component containing nonpropagating, closed, small ...

An algebraic approach to tempered distributions

Journal of Mathematical Analysis and Applications, 2011
The space \(S'(\mathbb{R}^N)\) of tempered distributions is shown to be isomorphic to a space \(B= B(M,G)\) of pseudoquotients. The Fourier transform of \(F\in B\) is defined as \(\widehat F: B\to S'\). The inverse Fourier transform is proved to be a continuous mapping from \(S'\) to \(B\).
