Al–Zn–Mg–Cu alloys are widely used in aerospace, with recrystallization significantly influencing their stress corrosion resistance. This study examines the impact of morphology on resistance a high‐alloying alloy, focusing lath‐shaped and equiaxed recrystallized grains. The findings reveal that, at same fraction, sample has 2.83 times higher current density 1.15 cracking susceptibility index than lath sample. However, its critical intensity factor is only 89.3% alloy's. Lath demonstrates...
The effect of Mg content on the evolution behavior inclusions in steel plates with deoxidation was investigated based experimental studies and thermodynamic calculations. Simulating welding process Charpy impact test were also carried out to evaluate Heat Affected Zone (HAZ) toughness plates. typical found steels complex comprising central oxide peripheral MnS. With increase samples from 0 27, 38 99 ppm, phase changed sequentially Al 2 O 3 (Mg‐Ti‐O), MgO, which is consistent calculation...
Superconductivity (SC) is one of the most intriguing physical phenomena in nature. Nucleation SC has long been considered highly unfavorable if not impossible near ferromagnetism, low dimensionality and, above all, out non-superconductor. Here we report observation with TC 4K Ni/Bi bilayers that defies all known paradigms superconductivity, where neither ferromagnetic Ni film nor rhombohedra Bi superconducting isolation. This unusual independent growth order (Ni/Bi or Bi/Ni), but sensitive...
The anomalous Hall effect in the ultrathin film regime is investigated Fe(001)(1--3 nm) films epitaxial on MgO(001). logarithmic localization correction to longitudinal resistivity and are observed at low temperature. We identify that coefficient of skew scattering has a reduction from metallic localized regime, while contribution side jump inconspicuous change except for small drop below 10 K. Furthermore, we discover intrinsic conductivity decreases with thickness 2 nm. Our results provide...
Abstract There are two kinds of mechanisms the improvement Heat Affected Zone(HAZ) toughness with fine inclusion particles. One is to prevent austenite grain growth during welding process aid pinning effect The other promote Intragranular Ferrite phase transformation oxide metallurgy technology strong deoxidizers developed in Baosteel. With particles, after high‐heat input 400 kJ/cm, average size decreased 61 µm HAZ, energy absorbed value increased 142 J for V notch Charpy test at 1653 K.
Although bulk Bi is a prototypical semimetal with topologically trivial electronic band structure, we show by various quantum transport measurements that epitaxial Bi(111) thin films have unexpected and nontrivial properties. Not only the top bottom but also side surfaces of are always robustly metallic while interior has already become insulating. We identify coupling between surface states drives two originally independent conducting channels into single connected one. The properties...
In this study, the as-cast microstructure and evolution of homogenized large-scale industrialized Al-Cu-Mg-Ag heat-resistant aluminum alloy ingots were investigated by means optical microscopy (OM), scanning electron (SEM), energy dispersive analysis (EDS), differential calorimetry (DSC). The results indicate that dendritic segregation is evident in ingot along radial direction, grain boundaries are decorated with lots net-shaped continuous eutectic structures. With homogenization time...
Abstract Selective Laser Melting is a promising manufacturing method for complex geometric fabrication. However, the 2xxx series aluminum alloy facing poor SLM-processibility problem. In this paper, impact of processing parameters on formability Al-Cu-Mg-Ag alloys was discussed. The evolution precipitation under different aging treatments explored. During formation process, samples with laser power 360 W and scanning velocity 1150 mm/s showed smaller defect fraction. Direct (DA) solid...
Using aberration-corrected scanning transmission electron microscopy, a new fully coherent precipitate platelet designated X′′, with flexible atomic layer FCC structure, was identified in low Cu/Mg ratio Al-Cu-Mg-Ag alloy. The emergence of the X′′ phase is primarily attributed to preferential segregation behavior Mg and Cu atoms towards {1 1 1}α Ag layers. strengthening mechanism principally driven by coherency strengthening, yielding efficient reinforcement (99.8 MPa increment per % volume...
Abstract During the immersion quenching process, severe temperature changes and significant differences between core superficial area can give rise to high residual stresses within aluminum alloy thick plate cause subsequent machining distortion of thin-walled part. Reducing stress effectively minimize in In this research, ABAQUS software was adopted simulate internal fields plates Al7055 during pre-stretching processes, sequentially respectively. addition, x-ray measurement method used...
