A high-performance pure-nickel magnetically-actuated microrobot (Ni-MAR) is printed by a ‘femtosecond laser polymerization + sintering’ method with great potential applications in controlled locomotion fast-flowing blood and massive drugs delivery.
The microstructure, mechanical properties and three-body impact abrasive wear behavior were investigated. results indicated that martensite transformation occurred even under air-cooling, fully martensitic structure consisted of lath a small amount twinned was obtained. And the auto-tempering during subsequent air cooling process, resulting in precipitation fine ellipsoidal V(C, N) particles acicular η-Fe2C cementite matrix. Meanwhile, tensile strength, yield Brinell hardness energy (−40 °C)...
This paper systematically studies the effect of quenching temperature on microstructure evolution and relationship between mechanical properties air-cooled TRIP steel prepared with C–Si–Mn hot-rolled sheet. The results indicate that when is lower than (200 °C) or close to (250 Ms temperature, martensite transformation mainly occurs during at early stage air cooling. When reaches 300 °C, lathy bainite begins form. As increases, morphology transformed from granular. Bainite cooling can promote...
The microstructure, mechanical properties and dry sliding wear behaviour of hot-rolled air-cooled medium manganese martensitic steel at different finish rolling temperatures (FRT) were investigated. fully structure with precipitation acicular carbides in the matrix was obtained process after hot rolling. With decrease FRT, resistance experimental steels significantly improved. worn surface morphology mainly furrows, mechanism micro-cutting. Both width depth furrows increased increasing...
In the present study, thermo‐mechanical controlled processing (TMCP) technology was applied to produce Ti–Nb–Mo microalloyed hot‐rolled steels. The strength at tail of a strip coil is often found be non‐uniform. microstructural and mechanical properties specimens in outermost circle as well third fifth from were analyzed detail. optical microscopy (OM) electron backscatter diffraction (EBSD) techniques are employed for characterization ferrite grains grain boundaries. precipitates revealed...
In this study, we investigate the microstructures and mechanical properties of quenching partitioning (Q&P) steels prepared with hot-rolled (HR) cold-rolled (CR) sheets at different annealing temperatures (partial austenitisation). The ferrite retained austenite are present in laths blocks HR-Q&P samples but mainly blocky CR-Q&P samples. Compared CR-Q&P, have higher content austenite, better elongation product strength (PSE). lath-shaped a ratio surface to volume is conducive homogenization...
The aim of this work was to develop a method evaluate the kinetics bainite transformation by theoretical deduction and thermal dilatation curve analysis. A Gleeble-3500 thermomechanical simulator dilatometer (DIL805A) were employed study isothermal in deformed (360 ∘ C , 600 860 ) undeformed conditions. information during recorded, curves well smoothed. By taking derivative dilation with respect time, peak time rate (PTTR) obtained, which can serve as essence time. relative change length ( Δ...
In this work, the precipitates in Ti-Mo-V steel were systematically characterized by high-resolution transmission electron microscopy (HRTEM). The thermodynamics and kinetics of Ti-Mo steels theoretically analyzed, effect vanadium on precipitation behavior was clarified. results showed that volume fraction significantly higher than steel. randomly dispersed interphase (Ti, Mo, V)C particles coexisted When temperature 872 °C, addition could increase driving force for austenite, resulting an...
Vanadium is a vital microalloying element in the precipitation hardening of hot‐rolled high strength steel. Its effects on continuous cooling phase transformation behavior, microstructure, and properties Ti–Mo Ti–Mo–V microalloyed ultra‐high steels are studied by thermal simulator, scanning electron microscopy (SEM), high‐resolution transmission (HRTEM), energy dispersive spectrometer (EDS), backscatter diffractometer (EBSD). The dynamic curves obtained which show that vanadium can restrain...
In order to investigate the influence of vanadium microalloying on deformation-induced pearlite transformation (DIPT) eutectoid steel, thermomechanical simulation tests were carried out in this study. The following four compositions applied tests: free Steel A, content 0.1 mass% B, 0.27 C, and with addition 0.02 N D. dissolution precipitation carbides, nitrides, or carbonitrides effect fraction morphology for different magnitudes strain examined, mechanism was elucidated. results revealed...
