The two-phase titanium alloy Ti–10 V–5Al-2.5Fe-0.1 B was taken as the experimental material, and thermal compression experiments were carried out at a deformation temperature of 770–920 °C strain rate 0.0005–0.5 s−1. An Arrhenius model, modified Johnson-Cook an improved BP neural network model based on sparrow search algorithm (SSA-BP) established to predict high rheological stress alloy. A comparison prediction accuracy three models made. When partial random data in curves used for building...
The Gleeble-3800 thermomechanical simulator unit was used to perform single-pass hot compression tests of the single-phase BCC structure AlFeCoNiMo0.2 high-entropy alloy at deformation temperature 950–1150 °C and strain rate 0.001-1s−1. behavior studied, dynamic recrystallization critical determined by work hardening rate. mechanism revealed with microstructure characterization techcique. study results showed: high entropy did not show any notable dependency on Without reaching temperature,...
Our micromagnetic calculation demonstrates that the dominant coercivity mechanism is self-pinning in most exchange-coupled permanent and composite magnets. Such a pinning attributed to change of intrinsic parameters associated with phase at interface. From this some more specific formulas on field can be derived. In particular, for sufficiently large soft grains/defects, expressed as HP=αHK, where HK=2k∕MS anisotropy α depends material structures. For an Nd2Fe14B–αFe system abrupt interface,...
As a novel metastable β titanium alloy, Ti-6Mo-5V-3Al-2Fe, it is essential to establish the correlation among its microstructure, strength and ductility. In this paper, transmission electron microscope (TEM) scanning (SEM) were used observe secondary α phase (αs) of aged alloy. The ductility alloy characterized by room temperature tensile test. dependence on αs was investigated. Results indicate that minimum width spacing within grains can be obtained after being at 470°C for 4h. increase...
This study explores the influence of particle size distribution (PSD) and heat treatment on 17-4 PH stainless steel fabricated by selective laser melting, which greatly improved elongation material basis ensuring strength. Scanning electron microscope backscattering diffraction were used to characterize microstructure steel. PSD+ PSD− samples have obtained equiaxed grain, internal tissue in sample crystals is uneven. By reason gas large partials powder falling into 49 μm–58.9 μm, it was...
In this work, an abnormal phenomenon of the superelastic cycle in NiTi alloy with R phase is reported. The transformation 500°C-annealed-sample B2-R-B19'. During first cycle, critical stress stress-induced martensitic (SIMT) reduced to 305.5 MPa and transition plateau shortened. With loading process, R–B19′ elastic deformation B19′ occur. unloading martensite reversal occurs high-density dislocation zone residual are formed. consumed. increase irreversible crystal defects leads deterioration...
Microstructure of novel high-strength metastable β titanium alloy, Ti–4Al–6Mo–2V–5Cr–2Zr, is extremely sensitive to both aging temperature and time length, which directly regulates their mechanical properties. Therefore, it particularly important clarify the roles treatment in microstructure properties Ti–4Al–6Mo–2V–5Cr–2Zr. Through varying from 520 640 °C 2 h 8 h, effects technological parameters on tensile Ti–4Al–6Mo–2V–5Cr–2Zr was systematically investigated. It noted that secondary α...
Abstract NiTi powders used for selective laser melting have here been fabricated by the breakup of discontinuous droplets in electrode induction gas atomization (EIGA). The morphology, particle size distribution, and hollow ratio powder were characterized scanning electron microscopy (SEM), analyzer, computed tomography (CT), respectively. effects pressure catheter length on distribution morphology then studied. Furthermore, classifier wheel speed yield 15–53 μ m classification process also...
