The High-Temperature Creep Behavior of In-Situ TiB<sub>2</sub> Particulate Reinforced Al12Si4Cu2NiMg Composite

In the present work, the in-situ TiB<sub>2</sub>/Al12Si4Cu2NiMg (denoted as &#8216;Al-12Si&#8217;) composites were successful synthesized through the salt-metal reaction route. The influences of weight fraction (0, 4, and 9 wt.%) and heat treatment (T5 and T7) on the tensile cree...

The creep deformation of the 4 wt.% TiB<sub>2</sub>/Al-12Si composite was controlled by the climb of dislocations in the aluminum alloy matrix.https://www.mdpi.com/2075-4701/8/11/917Al matrix compositesnano particlescreepload transfer
