200FEG field emission SEM with orientation analysis system. The voltage and current in electrochemical polishing were 20 V and 0.3 A, respectively. The time of electrochemical polishing was 35 s.... Annealing behavior of aluminium deformed by equal channel angular pressing [J]. Materials Letters, 2003, 57(24-25): 3767-3774. [3] NAGASEKHAR A V, TICK-HON Y, SEOW H P. Deformation behavior and strain......
in Category II is time-consuming and cumbersome. Compared to methods in Category I and Category II, establishing prediction models of subgrade soils is much simpler and more efficient. Therefore, many... soil, the resilient modulus is significantly correlated with the state and stress variables [27-29]. At the same time, ZHANG et al [14] also found that, for different soils, the influence of state......
1.1 kW electrical motor. The roll speeds were adjusted to provide sufficient time for solidification of the molten alloy in the cooling jacket and to avoid formation of possible internal cracks... A, 2020, 788: 139448. [20] REN X W, ZHANG X Y, HUANG Y C, LIU Y, ZHAO L K, ZHOU W L. Evolution of shear texture during the asymmetric rolling and its annealing behavior in a twin-roll casting AA6016......
or impurities in Mg matrix. The relatively short aging time and low temperature led to the precipitation of a small amount of Gd-containing particles or impurities as shown in Fig. 1. Such a small amount...; (1) where t is the immersion time. After immersion test, each specimen was characterized using OM......
] and the traditional phase-field method (TPF) [17-19], the proposed method can be self-consistently coupled from the time scale of atomic vibration characteristics (10-12 s) to the thermal and mass diffusion time scale (10-6 s) related to dislocation dynamics [20]. On this basis, the symmetry on the lattice level can be displayed to reflect the physical properties associated with certain......
time, the same controversy exists in the 316L stainless steel prepared by SLM. WANG et al [15] estimated the strength of SLM 316L stainless steel by Hall-Petch formula, and the cell size was used... and tensile samples were cut along the laser scanning direction. Microhardness was evaluated on the whole cross section with Vickers microhardness tester, subjecting to a load of 50 g and a dwell time......
work inspired us to employ the in situ thermo- mechanical treatment to refine the initial coarse grains of age hardening alloys, and at the same time introduce nanoscale precipitates in the grain... X Z, ZHU Y T, LAVERNIA E J. Mechanical behavior, deformation mechanism and microstructure evolutions of ultrafine-grained Al during recovery via annealing [J]. Materials Science and Engineering......
ratio of 10:1 was employed to fabricate the as-cast material into rods, and the extruded rods were then subjected to the stress-relief annealing at 450 °C for 1 h. The cylindrical hot compression......
]. Single-stage solution treatment (SST) is a commonly used solid solution method, where the single and constant temperature is used by only changing the holding time during the solution process [13]. WANG et al [12] revealed the evolution of the Fe-rich phase particles and recrystallization texture with solution time. HAN et al [13] found that the residual phases in AA7050 could be re-dissolved......
