This paper presents our latest studies on the effects of coiling temperature microstructure, precipitation behavior, and mechanical properties an Nb–Ti microalloyed steel produced by endless strip processing (ESP) coiled at different temperatures. The amounts soluble elements were measured using inductively coupled plasma optical emission spectrometry (ICP-OES). microstructure precipitates analyzed SEM, EBSD, TEM, electrolytic dissolution filtration tests. results revealed that large...
The high-temperature flow curves of the Fe–Mn–Al duplex steel showed an uncommon yield-like behaviour and abnormal dynamic recrystallisation that occurred at low temperatures rather than high temperatures. interaction strain partitioning unsynchronised softening in δ-ferrite austenite caused this peculiar behaviour. By discussing stress exponent apparent activation energy, respectively, temperatures, a modified hyperbolic sine function was developed to predict characteristic stresses....
The hot deformation behaviors of two Fe-Mn-Al lightweight steels were investigated by compression tests on a Gleeble-3500 thermal simulation machine over practical range temperatures and strain rates. Optical microscope (OM) electron backscattered diffraction (EBSD) carried out to observe the microstructural mo rphologies samples after deformation. Different from single austenite steel, duplex steel actually an austenite/δ-ferrite matrix with various phase compositions. At commencement...
Blazed grating is a key diffractive optical element in spectrometer. Different from the traditional holographic ion beam etching method, blazed has been fabricated on novel polymer with cyclic-azobenzene pendants (Pcyclic-azoMMA) by all fabrication two steps this paper. Firstly, use interfering Kr+ laser beams most efficient RCP+LCP polarization to inscribe symmetric surface relief gratings film. After that, make single perpendicular grooves irradiate slantly induce asymmetric structure. The...
The thermo-mechanical control processing of Nb-Ti micro-alloyed steel by induction heating in the endless strip production (ESP) line was analyzed to better understand microstructural evolution and Nb precipitation dissolution behavior austenite during rapid high temperatures. consisting 0.05 wt% C processed through simulated rough rolling at 1050 °C followed isothermal reheating 1150 °C. coarsening different holding times were compared, kinetics grains precipitates investigated. It found...
The method of building micro-structures on the surface certain materials could build a regular structure material to ensure consistency hydrophobic properties. In this paper, all-optical has been applied produce two-dimensional relief grating fluorine-containing azobenzene polymer film by using as an approach combined with material's properties photoresponsive and low energy. property final "two dimensional grating" also tested. Period combinations 500nm×500nm, 500nm×600nm, 600nm×700nm,...
