A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

The Numerical Simulation and Control of Microstructure in Heat-affected Zone in GMAW

Modern Applied Science, 2009
Summary: The grain size in heat affected zone (HAZ) of welding piece is an important element for evaluating the welding quality. The Monte Carlo (MC) technique, a stochastic simulation method, could be applied to simulate the microstructure in HAZ. A finite element model (FEM) was employed to simulate the GMAW temperature field and the data of the ...

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

Advanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.
