Analysis of Crystal Structure of the Welds with Friction-stir Welding Method on the Retreating Side for Bimetallic Disimilar Aa6061-cu Using Neutron Diffraction Techniques [PDF]

open access: yes, 2013
Crystal structure analysis has been performed on bimetallic disimilar Al-Cu. Neutron diffraction analysis shows that Al lattice parameter decrease from 4.09 Å to 4.05 Å while the Cu lattice parameter is relatively constant.

Impact of Surface Roughness on the Yield Drop of Hot‐Rolled AZX311 Mg Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Rough‐surfaced AZX311 Mg alloy samples have significantly lower yield strength than polished ones due to stress concentrators forming at V‐notch irregularities. Surface profilometry confirms higher Ra values for rough samples. Highest hardness values were observed near scratched surfaces, indicating strain localization effects near the rough surface ...

Kob-Andersen model crystal structure: genetic algorithms vs spontaneous crystallization [PDF]

open access: yesarXiv
For the first time, the crystal structure of the Kob-Andersen mixture has been probed by genetic algorithms calculations. The stable structures of the system with different molar fractions of the components have been identified and their stability at finite temperature has been verified.

Non‐Destructive and Mechanical Characterization of the Bond Quality of Co‐Extruded Titanium‐Aluminum Profiles

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Mathematical crystal chemistry II: Random search for ionic crystals and analysis on oxide crystals registered in ICSD [PDF]

open access: yesarXiv
Mathematical crystal chemistry views crystal structures as the optimal solutions of mathematical optimization problem formalizing inorganic structural chemistry. This paper introduces the minimum and maximum atomic radii depending on the types of geometrical constraints, extending the concept of effective atomic sizes.

KupferDigital: Ontology‐Based Digital Representation for the Copper Life Cycle

open access: yesAdvanced Engineering Materials, EarlyView.
It is demonstrated how data from different stages in the life cycle of a copper product can be stored in an ontology‐based data space. In order to showcase the methods and tools used in the project, four use cases are presented that show how data from different sources can be semantically described and queried from a shared data space.

Crystal Structure Generation Based On Material Properties [PDF]

open access: yesarXiv
The discovery of new materials is very important to the field of materials science. When researchers explore new materials, they often have expected performance requirements for their crystal structure. In recent years, data-driven methods have made great progress in the direction plane of crystal structure generation, but there is still a lack of ...

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

open access: yesAdvanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.
