Important Kind

Phase boundary is an important kind of interfaces for the dual-phase metals. Orientation relationship (OR) is a crucial factor affecting the performance of the phase boundaries and the dual-phase metals. Molecular dynamics simulation is performed to examine the structures of the bcc/fcc iron phase boundaries in Nishiyama–Wassermann (N–W) and Kurdjumov–Sachs (K–S) orientation relationships, and the performances of the dual-phase model with these ORs. The structural relaxation shows that the phase boundary with N-W relation has the lower energy than that in K-S relation. Stress-strain curves show that dual-phase model in N-W relation has the higher stiffness and strength than that in K-S relation. Simulation results show that phase boundary in N-W relation has a more exellent performance, and is preferred to be processed in heat treatment.

The Individual

An analytical model is developed to extend the single-phase model to dual-phase applications. The introduced dual-phase model helps in predicting ejector performance, particularly pressure recovery and efficiency, to entrained fluids of a liquid/gas mixture. The empirical loss coefficients are replaced by analytical equations accounting for the geometry of and flow conditions within the individual ejector components. In order to verify the present analytical model predictions, liquid ejector performance is studied experimentally when the entrained fluid is both a single-phase liquid (water) and a dual-phase liquid/gas mixture (water/air). The results show consistently better agreement with the experimental data than those delivered by existing models, reducing the root mean square error of the pressure recovery prediction to less than 10% of its former value.

Saturation Remanence

In the dual-phase model of interacting nanoparticles stretching leads to a decrease in both coercive force Hc and saturation remanence Irs , and compression — to their growth. Magnetostatic interaction between particles also decreases both Hc and Irs . Theoretical analysis was carried out in the framework of the dual-phase system of interacting particles on the example of nanoparticles γ-Fe2 O3, epitaxially coated with cobalt.

For fuel savings as well as energy and resource requirement, high strength low alloy steels (HSLA) are of particular interest to automobile industry because of the potential weight reduction which can be achieved by using thinner section of these steels to carry the same load and thus to improve the fuel mileage. Dual phase treatment has been utilized to obtain superior strength and ductility combinations compared to the HSLA of identical composition. Recently, cooling rate following heat treatment was found to be important to the tensile properties of the dual phase steels. In this paper, we report the results of the investigation of cooling rate on the microstructures and mechanical properties of several vanadium HSLA steels.The steels with composition (in weight percent) listed below were supplied by China Steel Corporation: 1. low V steel (0.11C, 0.65Si, 1.63Mn, 0.015P, 0.008S, 0.084Aℓ, 0.004V), 2. 0.059V steel (0.13C, 0.62S1, 1.59Mn, 0.012P, 0.008S, 0.065Aℓ, 0.059V), 3. 0.10V steel (0.11C, 0.58Si, 1.58Mn, 0.017P, 0.008S, 0.068Aℓ, 0.10V).
