Abstract Magnesium alloys are highly desirable for a wide range of lightweight structural components. However, rolling Mg can be difficult due to their poor plasticity and the strong texture yielded from often results in plate forming ability, which limits further engineering applications. Here we report new hard-plate (HPR) route achieves large reduction during single pass. The Mg-9Al-1Zn (AZ91) plates processed by HPR consist coarse grains 30–60 μm, exhibiting typical basal texture, fine...
In this paper, we took cold-rolled Al-Cu5.0-Mg0.5-Si0.5 alloy as the research object. The roles of 0.1 wt% in-situ nano-TiC and nano-TiC-TiB2 in solid–liquid solid-state transformations (solution plus aging precipitation) were systematically investigated compared. We found that trace nanoparticles can stimulate nucleation α-Al dendrites hinder their growth, meanwhile serving heat storage sustained-release carriers during transformation. process transformation, recrystallization is promoted,...
Featuring low density and high specific strength, magnesium (Mg) alloys have attracted wide interests in the fields of portable devices automotive industry. However, active chemical electrochemical properties make them susceptible to corrosion humid, seawater, soil, medium. Various strategies revealed certain merits protecting Mg alloys. Therein, engineering self-repairing coatings is considered as an effective strategy, because they can enable timely repair for damaged areas, which brings...
In the context of global carbon neutrality, application lightweight magnesium alloys is becoming increasingly attractive. this study, selective laser melting (SLM) was employed to achieve nearly full dense and crack-free AZ91D components with fine equiaxed grain structure. The formation mechanism typical pore defects (gas pore, lack-of-fusion keyhole pore) modes (keyhole mode conduction mode) were systematically studied by varying power scanning speed. morphology volume fraction pores under...
The age-hardening behavior and precipitation evolution of an isothermal aged Mg−5Sm−0.6Zn−0.5Zr (wt.%) alloy have been systematically investigated by means transmission electron microscopy (TEM) atomic-resolution high-angle annular dark field scanning (HAADF-STEM). Vickers hardness the present increases first then decreases with ageing time. sample at 200 °C for 10 h exhibits a peak-hardness 90.5 HV. In addition to dominant β0′ precipitate (orthorhombic, = 0.642 nm, b 3.336 nm c 0.521 nm)...
In the present work, type, morphology and size of secondary phase particles in a Mg–4Al–2Sn-0.5Ca (ATX420) alloy are tailored through sub-rapid solidification (SRS) aging treatment before friction stir processing (FSP) to systematically investigate their impact on microstructures mechanical properties FSP ATX420 Mg alloy. The smaller eutectic CaMgSn with micro-defects as-cast SRS is more likely be broken during FSP, compared conventional (CS) Additionally, nano-sized Mg17Al12 precipitate...
The tensile creep behavior of Al-Cu-Mg alloy and its composite containing in situ nano-sized TiCx were explored at temperatures 493 K, 533 K 573 with the applied stresses range 40 to 100 MPa. reinforced by particles exhibited excellent resistance ability, which was about 4-15 times higher than those unreinforced matrix alloy. stress exponent 5 noticed for both composite, suggested that their related dislocation climb mechanism. During deformation elevated temperatures, enhanced mainly...
