A new alloy for drive-train applications with a significant addition of vanadium is presented. The influence to air-hardening forging steels investigated and discussed. For the investigations, laboratory melt casted forged into rod. mechanical properties microstructure are described compared vanadium-free reference from previous study. component shows high strength hardness in as-forged state (...

We survey some known results concerning the asymptotic behavior of solutions to defocusing nonlinear Schrödinger equations. In particular, we discuss the H1 scattering theory for intercritical NLS, as well as the scattering theory in weighted spaces for the mass-subcritical case. We also discuss an instance of modified scattering in the long-range case.

Developing medium-Mn steels (MMnS) demands a better understanding of the microstructure evolution during thermo-mechanical treatments (TMTs). This study demonstrates relationship among processing, microstructure, and mechanical properties warm-rolled steel containing 1.5 wt. % Cu Ni. After short-time warm rolling (WR) in an intercritical temperature range, significant quantity (40.6 vol.%) aust...

The distribution of the characteristic texture components between the ferrite grains of different size classes has been studied in a steel with 0.082%C, 1.54% Mn, 0.35% Si, 0.055%Nb and 0.078%V after different rolling schedules with a final rolling temperature above or below Ar3. Microstructures and textures were characterized by means of optical microscopy and orientation microscopy. A strong ...

TRIAL DESIGN In the double-blind, randomized, controlled trial, we aimed to evaluate the effects of compound tufuling oral liquid (CoTOL) on serum uric acid (sUA) levels and recurrence of acute gouty arthritis in intercritical and chronic gout treatment. METHODS A total of 210 patients with gout were screened from 8 hospitals to observe the sUA and acute gouty arthritis recurrence rate-reduci...

The effects of starting microstructure and intercritical annealing temperature on the phase-transformation kinetics microstructural evolution a prototype Fe–0.15C–5.56Mn–1.1Si–1.89Al medium-Mn third-generation advanced high-strength steel are examined. microstructures comprise 1) an as-received cold-rolled (CR) containing significant fraction ferrite tempered martensite 2) austenitized quenched...

Abstract The processability of medium Mn-containing steels (MMnS) with 4–10% Mn is discussed in light their continuous casting behavior. Precipitation, phase transformation, extension, or shift solidification intervals induced by various alloying concepts are decisive controlling the hot ductility. It turns out that formation complex AlN and MnS precipitates as well ??ferrite deteriorates high ...
