Abstract Magnesium alloys with high strength and excellent corrosion resistance are always sought-after in light-weighting structural components for automotive aerospace applications. However, most magnesium that have a specific strength, they usually an inferior vice versa. In this work, we successfully develop Mg-11Y-1Al (wt. %) alloy through conventional casting, solution treatment followed by extrusion. The overall properties of feature rate lower than 0.2 mm y −1 , yield 350 MPa...
In this study, we investigated the oxidation of Mg-11Y-1Al alloy at 500°C in an Ar-20%O2 environment. Multiscale analysis showed network-like long-period stacking ordered (LPSO) phase transformed into needle-like LPSO and polygonal Mg24Y5 phases, leading to formation a high-dense network oxides front. These grew laterally along oxide/matrix interfaces, forming thicker, continuous scale that effectively blocked elemental diffusion. Hence, preferential is believed accelerate thicker oxide...
Micro-alloying Mg alloys with rare earth elements is an economical and promising way to improve their corrosion resistance. It of great importance understand behavior for designing corrosion-resistant alloys. In this work, Mg-11Al-0.2Y alloy was prepared exploring its in 3.5 wt.% neutral NaCl solution. exhibits a low current density 2.3 μA/cm2 after immersion 1 d due the formation protective surface film containing Al2O3, MgO Mg(OH)2. However, nano-scaled pores exhibit at film/matrix...
Static recrystallization of a high strain rate compressed Mg-1 Zn (wt.%) alloy was investigated using electron backscattered diffraction (EBSD). A novel 53°〈101¯0〉 structure observed in the as-deformed alloy, which showed {101¯2}-{101¯2} double twin relationship with matrix. When annealed at 200 °C, {101¯1} compression twins and {101¯1}-{101¯2} higher priority to recrystallize. In addition, coarse {101¯2} tension their inner were preferentially recrystallize, while lenticular had little...
Mg-Y based alloys exhibit a promising combination of strength and deformability through tuning precipitation solute strengthening mechanisms tailoring the activity non-basal dislocations. Understanding sequence its dependence on Yttrium concentration in matrix will provide guideline for fine structure, morphology distribution precipitates alloys. In this paper, we explore behaviors Mg-11Y (wt%) Mg-11Y-1Al using aberration-corrected scanning transmission electron microscopy, rationalize...
Precipitation strengthening represents a crucial approach in the realm of metals, with particular significance for magnesium. In this study, complex LPSO–precipitate structure, which is constituted principal secondary phases Mg rare earth (RE) alloys, namely Long-Period Stacking Ordered (LPSO) phase and aging precipitate, was successfully fabricated within Mg-11Y-1Al alloy. Subsequently, an in-depth investigation conducted regarding interaction between dislocations structure under varying...
AbstractMicrostructures and mechanical properties of the Mg–5Gd–2Y–2Zn–0·5Zr alloy (wt-%) in as cast solution treated conditions have been investigated using optical microscopy, scanning electron microscope, X-ray diffraction, probe microanalyser transmission microscope. The results show that after adding element Y, forms Mg12Zn(Y, Gd) phase with 18R-long period stacking ordered (LPSO) structure, Gd atoms can slow down transition process 18R to 14H high temperature treatment. LPSO grain...
