The influence of extrusion temperature and speed on the microstructures mechanical properties as-extruded Mg–6Zn–1Y–0.85Zr (ZWK610) alloy was inquired by indirect at three ram speeds (1, 3 6 mm/s) extruding temperatures (250, 300 350 °C). extruded organization mainly consists equiaxed finely dynamic recrystallized (DRXed) grains, elongated coarse un-DRXed grains massive W–Mg3Y2Zn3 I–Mg3Zn6Y phases. increasing result in larger DRXed higher volume fractions fewer second phase fractions....
The impact of microstructure evolution on the mechanical properties a typical 500 MPa-grade weathering steel produced by an identical thermo-mechanical control process and different tempering treatments at 450–650 °C were thoroughly investigated mainly using scanning electron microscopy (SEM) equip with backscatter diffraction (EBSD), high-resolution transmission (HRTEM), X-ray diffractometer (XRD). Results indicated that as-rolled consists granular bainitic ferrite (GBF) considerable amount...
This study investigates the effects of molybdenum (Mo) and boron (B) on microstructures impact properties in coarse grain heat-affected zone (CGHAZ) a low-carbon V-Ti-N steel. The results demonstrate that, at heat input up to 75 kJ/cm, addition Mo alters microstructure CGHAZ, transforming it from polygonal ferrite (PF) + degraded pearlite (DP) composition granular bainite (GB) small amount acicular (AF). transformation increases energy 20 J 35 J. Furthermore, with Mo/B composite addition,...
This study focuses on researching the influence of Mo corrosion mechanism 1%Ni weathering steel (WS) in simulated marine atmospheric conditions. The element is involved reaction, and after hydrolysis, MoO2 MoO3 are produced. deposition occurs cracks fissures, rendering rust layer more uniform homogeneous. It also furnishes nucleation sites for amorphous oxyhydroxide, which turn promotes interweaving a nanosized oxyhydroxide network. As result, develops into physical barrier that acquires...
Abstract Surface modification is an important technique for maintaining relatively favorable mechanical properties to surface and corrosion resistance. In this study, shot peening technology applied low alloy steel production nanocrystallines. The microstructure near the layer was characterized by x-ray diffraction, transmission electron microscopy backscatter diffraction. behavior of shot-treated analyzed polarization pitting test, morphology corroded sample observed a scanning microscope....
The biodegradable Mg–2Zn-1Gd-0.5Zr-xCu (x = 0, 0.1, 0.3, 0.5 wt.%) alloys are prepared to evaluate their microstructures, corrosion behavior, biocompatibility and antimicrobial properties. When the Cu element adds alloys, new MgZnCu phase generates in addition MgZn2 phase, W–Mg3Gd2Zn3 I–Mg3Gd6Zn phase. With content increases, grains become finer. Meanwhile, shape of transforms from spherical elongated into reticular. grain boundary, reticular act as physical barriers hinder spread corrosion....
Welding thermal cycles with heat inputs ranging from 25 to 75 kJ/cm were performed on a Gleeble 3500. The impact energy improved significantly (from 10 112 J), whereas the simulated coarse-grain heat-affected zone (CGHAZ) microstructure changed lath bainite ferrite (LBF) and granular (GBF) + martensite/austenite (M/A) acicular (AF) polygonal (PF) M/A as input increased. Simultaneously, mean coarse precipitate sizes degree of V(C,N) enrichment surface increased, which provided favorable...
It is difficult for traditional weathering steel (WS) to form a protective rust layer withstand the chloride ions and high humidity. Hence, there an urgent need develop new type of low-cost WS with excellent corrosion resistance in containing NaCl environment. This study aims determine influence Cu on mechanism 1%Ni simulated atmospheric environments. By increasing content (0.15–0.55%), enhanced. The promotes formation stable compact layer, significantly enriching proportion α-FeOOH equip...
The present research on the microstructure-tensile property relationship of low carbon microalloyed steel mainly focuses effects microstructure type and its simple morphology inclusding size shape etc., but correlation between dislocation substructure tensile properties seems more essential requires additional estimation. In this study, four typical manganese (Mn) containing (from 1.08–1.77%) low-carbon steels were prepared by Thermo Mechanical Control Process (TMCP), correlations among Mn...
