Influence of cooling mediums on mechanical and tribological characteristics of Al/Cu-based composites reinforced with chromium particles [PDF]

Tribology and Materials
The intensity of radial heat flux during quenching affects the microstructural features of materials. The interface strength is also affected by the radial heat flux in the case of metal matrix composites (MMCs).
