The microstructure, mechanical properties and fracture behavior of as-cast Mg-10Gd-3Y-xZn-0.6Zr (x = 0, 0.5, 1 2 wt%) alloys have been investigated by X-ray diffraction (XRD), optical microscopy (OM), scanning electron (SEM) tensile tests. experimental results reveal that the microstructure alloy without Zn contains α-Mg Mg24(Gd,Y)5 phase, with 0.5% contained α-Mg, (Mg,Zn)3(Gd,Y) Mg24(Gd,Y,Zn)5 whereas when content was 1% 2%, Mg12(Gd,Y)Zn phase some needle-shaped stacking faults notably...
The effects of the rare earth element La on microstructure and mechanical properties cast Al-5.4Cu-0.7Mg-0.6Ag alloys have been investigated through metallographic observation, scanning electron microscopy analysis, transmission microscopy, X-ray diffraction, tensile testing. present form action mechanism analyzed. findings indicate that inclusion trace amounts markedly diminishes grain size in Al-Cu-Mg-Ag alloy. Furthermore, as content increases, alloy's strength is significantly improved....
The low-cost Ti-1Al-8V-5Fe (Ti-185) alloy with a high strength is prepared by cold-compaction-and-sintering powder metallurgy process titanium hydride (TiH2) powders and FeV80 master powders. use of simple technique cheap alloying elements can lead to the cost reduction for alloys. thermal decomposition TiH2-1Al-8V-5Fe analyzed gravimetric analyses differential scanning calorimetry simultaneous analyzer. shrinkage behavior during sintering employed high-sensitivity dilatometer system....
Abstract A complex two‐dimensional (2D) hierarchical heterostructure was fabricated by a sequential seeded self‐assembly, which consisted of laterally grown nanotubes from one perylene monomer and terminally elongated nanocoils similar on microribbon seeds third perylene. Because the nanotube nanocoil monomers can form kinetically trapped off‐pathway aggregates to prevent self‐nucleation have molecular organizations different facets seeds, preferentially nucleate grow seed sides terminal...
Micromorphology and atomic arrangement on ligament surface of nanoporous metals play a vital role in maintaining the structural stability, adjusting reaction interface endowing functionality. Here we offer an instructive scientific understanding for temperature-induced reconstruction structure evolution copper (NPC) based systematically experimental observations theoretical calculations. The results show that with dealloying temperature increasing, micromorphology NPC evolves from smooth to...
Purpose The influence of Zn concentration on microstructure and corrosion performance the Mg–xZn alloys microalloyed with Ca Ce was investigated through optic microscopy, scanning electron hydrogen evolution, dynamic polarization electrochemical impedance spectroscopy experiments. Design/methodology/approach In this paper, (x = 0.5∼2.0 Wt.%) (0.2 Wt.% each) were prepared. Findings As increase concentration, number second phase particles (Mg-Zn-Ca, Mg-Zn-Ce Mg-Ce phases) increased, when...
The effect of Ca on the microstructure and corrosion behavior a single-phase Mg–Sc alloy was investigated. characterized by optical microscopy scanning electron microscopy. Corrosion measured hydrogen evolution tests electrochemical measurements. With addition microalloyed Ca, grain size Mg-0.3Sc is refined Mg2Ca phase particle precipitated. test results reveal that beneficial to resistance alloy, which related refinement protective performance product film. As content increases, first...
