Abstract
As-extruded Mg-6Al-1Zn-0.5Cu and Mg-6Zn-0.5Cu alloys with comparable strength were prepared, and their dissolution behaviors in KCl solutions with different Cl

concentrations were investigated for use as fracturing balls. The results of electrochemical and immersion tests consistently demonstrated that Mg-6Al-1Zn-0.5Cu alloy exhibited superior corrosion resistance across all tested environments. Specifically, in 1 wt.% KCl, it displayed a lower corrosion current density (1.28 × 10

Highly alloyed Al–Zn-Mg-Cu alloys with elevated Zn contents are promising candidates for next-generation ultra-high-strength structural applications. In this work, five Al–Zn–Mg–Cu-Zr alloys containing 8–12 wt.% Zn were fabricated, and two solution treatment durations (1 h and 2 h) were employed to investigate their ef...

The present study investigates the effects of low-cost alloying elements (Si, Mn, Fe, and Zn) on the corrosion behaviour, ion release, and surface characteristics of β-type Ti-35Nb-7Zr-4Ta (TNZT) composites for biomedical implant applications. TNZT-xSi-y (Mn/Fe/Zn) composites, where x = 0.5, 0.75, and 1.0 wt.% and y...

Aluminum–copper (Al–Cu) alloys reinforced with silicon carbide (SiC) are attractive for marine applications, yet their corrosion behavior is reported inconsistently in the literature: SiC has been described as both a physical barrier and a galvanic catalyst, depending on its content and distribution. To clarify this, t...

The goal of this project was to investigate the microstructure, hardness as well as corrosion behavior of Al - 4% Mg metal matrix composites containing boron carbide (B₄C) particles at different weight fractions (3, 6, and 9 wt.%). Composites were produced through powder metallurgy by compacting, sintering and characte...
