Influence factors on wear resistance of two alumina matrix composites [PDF]

, 2008
We measured the wear resistances of alumina, alumina/silicon carbide composite and alumina/mullite composite by abrasive wear. And we studied the influence of fracture mode and worn surface pullout on wear resistance. The results are as follows: the main

RESISTANCE OF COATED ELECTRODES SUITABLE FOR RENOVATION OF TILLAGE TOOLS [PDF]

Journal of Central European Agriculture, 2013
This article deals with the abrasive wear resistance of additional materials. The resistance of individual materials was figured out by determining a proportional wear resistance on a grinding fabric.

Breaking through the strength-ductility trade-off of LPBF-produced Ti-xNb alloys from mixed powders via ω-phase induced heterostructure

International Journal of Extreme Manufacturing
Ti- x Nb alloys produced by laser powder bed fusion (LPBF) from mixed powder usually exhibit an inhomogeneous elemental distribution, leading to a deterioration in mechanical properties.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
