A Surface Analytical Method for Determining the Porosity of Tungsten Coatings as Hydrogen Permeation Barriers

Surface and Interface Analysis, Volume 58, Issue 1, Page 3-8, January 2026.
ABSTRACT Fast and reliable methods that permit the determination of the through‐thickness coating porosity are required to develop optimized coating–substrate systems that act as hydrogen permeation barriers. In this work, we present an analytical approach for determining the porosity of tungsten coatings that are 1.5 and 3 μm thick.

Analysis of acoustic emission during the melting of embedded indium particles in an aluminum matrix: a study of plastic strain accommodation during phase transformation

, 2012
Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change.

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.
