The relationship between activities of involved deformation mechanisms and the evolution microstructure texture during uniaxial tension AZ31 magnesium alloy with a rare non-basal has been thoroughly investigated in present study by means electron backscattered diffraction (EBSD) measurement visco-plastic self-consistent (VPSC) modeling. These results show that except basal <a> slip prismatic slip, {101¯2} extension twin (ET) also plays significant role plastic deformation. With increasing...
Cryogenic rolling experiments have been conducted on the AZ31 magnesium (Mg) alloy sheet with bimodal non-basal texture, which is fabricated via newly developed equal channel angular and continuous bending process subsequent annealing (ECAR-CB-A) process. Results demonstrate that this shows no edge cracks until accumulated thickness reduction reaches about 18.5%, 105.6% larger than of traditional basal texture. Characterization including optical microstructure (OM), X-ray diffractometer...
Abstract A novel forging process has been designed for better mechanical properties of Ti-43Al-6Nb-1Mo-1Cr-(0,0.6)B alloys in this paper. Multi step could provide much finer microstructure, higher room-temperature strength, increased high-temperature strength and elongation with these alloys. The forged without boron exhibit as 676.05 ± 11.37 MPa 41.32 1.38% at 800 °C, while the average grain size represents 12.63 3.77 μm. 0.6 at.% B represent than boron, due to refined microstructure...
Isothermal hot compression experiments were conducted on homogenized Mg-8.5Gd-4.5Y-0.8Zn-0.4Zr alloy to investigate deformation behavior at the temperature range of 673–773 K and strain rate 0.001–1 s − 1 by using a Gleeble-1500D thermo mechanical simulator. Metallographic characterization samples deformed true 0.70 illustrates occurrence flow localization and/or microcrack conditions 673 K/0.01 1, K/1 698 indicating that these three should be excluded during working alloy. Based measured...
The porosity deteriorates the mechanical properties of nickel‐based superalloys, especially fatigue properties. Herein, kinetics model homogenization growth is optimized. corresponding diffusion processes during solution heat treatment are simulated by DICTRA software and verified experiments. results show that increases first then decreases treatment, due to imbalanced flux between dendritic core (DC) interdendritic areas (IAs). flows toward DC IAs after fully fast elements. Moreover,...
To investigate effects of carbon addition on microstructural characteristics rapidly solidified TiAl alloys, Ti–43Al–6Nb-xC (x = 0,0.5,1.0 at.%) powders are produced by plasma rotating electrode process (PREP). Due to the greater viscosity composite melts with carbides than those without carbides, average sizes containing much larger theoretical diameters. In addition, phase compositions carbon-free usually consist α and β phase, while is predominant in due α-phase stabilizer. β→α...
