Kinetics Of

Dual phase (DP) steels are widely applied in today’s automotive body design. The favorable combination of strength and ductility in such steels is in first place related to the share of ferrite and martensite. The pronounced work hardening behavior prevents localized thinning and allows excellent stretch forming. Niobium microalloying was originally introduced to dual phase steel for improving bendability by refining the microstructure. More recently developed “high ductility” (HD) DP steel variants provide increased drawability aided by a small share of austenite retained in the microstructure. In this variant niobium microalloying produces grain refinement and produces a dispersion of nanometer-sized carbide precipitates in the steel matrix which additionally contributes to strength. This study investigates the microstructural evolution and progress of niobium precipitation during industrial processing of high-ductility DP 980. The observations are interpreted considering the solubility and precipitation kinetics of niobium. The influences of niobium on microstructural characteristics and its contributions to strength and formability are discussed.

The aim of the present study was to evaluate the performance of Ventilan® coupled to the Volumatic® spacer. An experimental study was conducted using the four stage Multistage Liquid Impinger (MSLI). This enabled the observation that half of the pharmacological dose is retained within the body of the spacer. Therefore, the air flow inside the spacer was studied, along the respiratory cycle, using Fluent™. Several recirculation regions were observed inside the spacer that may influence the aerosol flow and also the deposition of the drug.

As a new type of section, central-open box sections are more and more popular. Some existed bridges of central-open box section can not to be used because of vortex-excited resonance. Based on this situation, the paper taking the Hongkong-Zhuhai-Macao River-sea ship canal Bridge for example, takes measures of taking the central bottom plate opening hole, changing the angle of web, and setting baffle, according the experimental study and CFD analysis, it is obtained that different aerodynamic sections are various in the character of vortex-excited, although taking the central bottom plate opening hole is effective, it only refers to the best opening ratio, changing the angle of web can not improve the vortex-excited effectively, setting baffle on the lateral sides is the most effective measure to forbid the vortex-excited resonance.
