Analysis of the structure of a hard metal: a simple method of relating properties to stereological structures

Materials Research, 2005
Computer simulation of the hard phase of WC-based hard metals is not common in scientific literature. This phase is formed by carbide grains embedded in a metallic matrix. In the equilibrium state, the grain has an equilateral prismatic form with beveled

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.
ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Intermetallic Compound Layer Morphology and Distribution in Friction‐Welded Steel–Aluminum Components

Advanced Engineering Materials, Volume 27, Issue 16, August 2025.
In this study, how friction‐welding parameters (rotational speed, etc.) affect the morphology, distribution, and local thickness of the intermetallic compound layer (IMC‐layer) in friction‐welded steel‐aluminum hybrid components is investigated. In the results, it is shown that lower speeds (700 rpm) lead to a more uniform, thinner IMC‐layer (<0.5 μm),

Process Parameter and Dimension‐Dependent Mn Vaporization During Laser Powder Bed Fusion of an Fe–Mi–Si–Cr‐Based Shape Memory Alloy

Advanced Engineering Materials, Volume 27, Issue 15, August 2025.
The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...

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.

High tin or high lead: distinctive alloying practices of the pastoral Yuhuangmiao culture in Northeast China during the first millennium BCE

Archaeometry, Volume 67, Issue 4, Page 1040-1056, August 2025.
Abstract The Jundushan cemetery, located on the northern boundary of the present‐day Beijing, sits at a crucial nexus between the Yan and Taihang mountains linking northern and central China. This strategic location provides an interesting case for examining interactions between pastoralism and agriculture around the early half of the first millennium ...

Internal Material Flow Layers in AA6082-T6 Butt-Joints during Bobbin Friction Stir Welding

Metals, 2019
Bobbin friction stir welding with a double-sided tool configuration produces a symmetrical solid-state joint. However, control of the process parameters to achieve defect-free welds is difficult. The internal flow features of the AA6082-T6 butt-joints in
