Elevated temperature fracture of RS/PM alloy 8009: part i. fracture mechanics behavior
TL;DR: In this article, the authors show that increasing temperature and decreasing loading rate degrade the plane strain initiation (KICifrom the integral) and growth (tearing modulus,TR) fracture toughnesses of RS/PM 8009 (Al-8.5Fe-1.3V1.7Si, wt pct).

The history and necessity of mechanical alloying
TL;DR: The ball-milling process was used to make metal powders for wetting studies as a means of making the alloy itself by powder metallurgy as mentioned in this paper, and it is well established that melting and casting techniques, using of fine inert particles or so-called filamentary reinforcements with high temperature strengths combined with soft conventional matrix metals can produce composites which outperform superalloys.

TL;DR: In this paper, the quality of matrix-reinforcement bonding has been quantified by the reinforcement influence distance, defined as the distance from the particle at which the nanohardness of the matrix drops to its asymptotic value.

Structure, properties and fracture of friction stir welds in a high-temperature Al-8.5Fe-1.3V–1.7Si alloy (AA-8009)
TL;DR: Friction stir welds produced in a rapidly solidified, powder metallurgy Al-8.5Fe-1.7 Si (wt.%) alloy were characterized in order to investigate the effects of deformation during welding on the weld zone microstructure, hardness, tensile properties, and fracture behavior as mentioned in this paper.
