Quantitative analysis of precipitation and strengthening mechanisms of V and V-Ti hot-rolled microalloyed steels

Zimeng Zhu et al.

Summary: This study comparatively investigates the microstructure, precipitation behavior, and mechanical properties of hot-rolled V and V-Ti microalloyed steels. The results show that the substitution of trace Ti affects the grain size and precipitation behavior of V, leading to a decrease in yield strength of the traditional hot-rolled steel.

Effects of surface roughness on interfacial dynamic recrystallization and mechanical properties of Ti-6Al-3Nb-2Zr-1Mo alloy joints produced by hot-compression bonding

Bijun Xie et al.

Summary: Surface roughness affects the interfacial dynamic recrystallization kinetics and mechanical properties of hot-compression bonding joints of Ti-6Al-3Nb-2Zr-1Mo. Rough surfaces lead to the formation of elongated grains with lower elongation compared to polished surfaces. A rotational dynamic recrystallization mechanism is proposed to explain the formation of fine interfacial recrystallization grains during bonding of rough surfaces.

Effect of Vanadium and Strain Rate on Hot Ductility of Low-Carbon Microalloyed Steels

Siying Song et al.

Summary: This study investigated the effect of strain rate and vanadium content on the hot ductility of low-carbon microalloyed steels through hot tensile tests. The results show that low strain rate leads to poor hot ductility, while high strain rate improves it. Increased vanadium content results in decreased hot ductility at low temperatures, but slightly improves it at high temperatures.

Formation mechanism and control of transverse corner cracks in fine blanking steel

Fujun Zhang et al.

Summary: In this study, the mechanism of corner cracks in fine blanking steel produced on straight arc caster was investigated. The corner temperature distribution of a continuous casting slab was calculated using the transient thermal module of Ansys, and the thermoplastic curves of test steel grades were obtained. Through various tests and examinations, the role of different factors in the formation of corner cracks was determined, and corresponding control measures were formulated to eliminate the cracks.

Isothermal transformation and precipitation behaviors of titanium microalloyed steels

Xiang-dong Huo et al.

Summary: The microstructure transformation and precipitation behavior of nano-carbides in Ti microalloyed steel during isothermal process were studied, and it was found that gamma -> alpha phase transformation and TiC precipitation occur during the process. The interphase precipitation of TiC mostly occurs at the period of the phase transformation, while the random precipitation of TiC mostly occurs on the ferrite after the phase transformation. Initial increment in yield strength comes from phase transformation strengthening, and precipitation hardening effect becomes more important with increase in isothermal time, reaching maximum value at the precipitation finished point of the PTT curve.

Formation and Control of Transverse Corner Cracks in the Continuous Casting Slab of a Microalloyed Steel

Yadong Wang et al.

Summary: The study revealed that transverse corner cracks tend to appear on the valleys of oscillation marks on the continuous casting slab, accompanied by refining microstructures in the vicinity of the cracks. By optimizing the secondary cooling scheme, it is possible to prevent the temperature at the slab corner in the bending and straightening zone from entering the brittle zone, significantly reducing the occurrence of transverse corner cracks.

Study on the mechanism of titanium improving the hot ductility of peritectic microalloyed steels in brittle zone III

Xiaogang Yang et al.

Summary: The study found that titanium has a significant influence on the hot ductility of peritectic-microalloyed steels in the temperature range of 600 to 950 degrees Celsius. Titanium-bearing steels showed a reduction in area values greater than titanium-free steels, mainly due to the formation of precipitates and oxides that promote ductile fracture. Additionally, the refinement of austenite grain and the reduction in thickness of ferrite films along grain boundaries contributed to the improvement in hot ductility.

Understanding the high temperature side of the hot ductility curve for steels

B. Mintz et al.

Summary: The study found that dynamic recrystallisation cannot occur during straightening of steel, leading to a possible overestimation of ductility, especially for steels with deformation induced ferrite films where cracking is less likely. However, for TWIP steels, cracking can occur even with high measured ductility due to the possibility of insufficient recrystallisation.

Characterization of the Microstructures and Dynamic Recrystallization Behavior of Ti-6Al-4V Titanium Alloy through Experiments and Simulations

Hongchao Ji et al.

Summary: The study investigated the microstructure evolution and hot compression behavior of TC4 titanium alloy under different deformation conditions through experiments and simulations. The results showed that higher temperatures and lower strain rates promoted DRX behavior, and the softening effect increased significantly with temperature during compression at certain strain rates. A DRX kinetics model was established to predict volume fraction and grain size, and the relationship between microstructure, deformation behavior, and mechanical properties was discussed. The finite element model combined with kinetic equations accurately predicted the microstructure after hot compression, demonstrating excellent applicability and potential in predicting mechanical properties.
