Websteels. The electropulsed microstructure in the annealed samples is similar to that of the cold-drawn samples. However, electropulsing the cold-drawn pearlite steel wire … WebAustenite reversion during tempering of a Fe–13.6 Cr–0.44 C (wt.%) martensite results in an ultra-high-strength ferritic stainless steel with excellent ductility. The austenite reversion mechanism is coupled to the kinetic freezing of carbon during low-temperature partitioning at the interfaces between martensite and retained austenite and ...
The stability of precipitates under electropulsing in 316L stainless steel
WebAn electropulse with peak current density 9×10 9 A m –2 and pulse duration 150 μs has been implemented on the cold worked pearlitic steel sample at ambient temperature. … WebApr 1, 2003 · The as-received low-carbon steel consists of coarse-grained ferrite (α-Fe) and little pearlite. After the electropulsing treatment, many nanostructured areas consisting of γ-Fe and Fe 2 O 3 were formed in the former α-Fe grains, as shown in Fig. 2.The diffraction rings, shown in the inset, reveal that the nanocrystallites are randomly distributed, and … eggs color sheet

WebFeb 1, 2015 · The electropulse was generated by an Avtech AV-108F-B-P Current Pulser which converted the direct current into pulsed current. The direct current power source has a standard output power of 80 W and a standard output electric potential of 20 V. The pulse width, peak current intensity, pulse frequency and pulse trigger mode are programmable. WebIn the case of electropulsed steel, the particles are dispersed with the varied size of 25−105 nm, and its distribution mainly concentrates in 25 nm (Fig 3 (h)). Furthermore, … Websteel alloyed with Co, in which it was rationalized by the increase in ferrite cementite interfacial area [24]. The excess free energy, however, has been released at austen-itizing temperature due to the lost of electropulse-induced structure. In the DSC cooling stage, both the electropulsed and un-electropulsed show that same behaviors, as illus- eggs coloring pages printable
