The purpose of the investigation is to theoretically and experimentally explore the method and key techniques of using extrusion-die to manufacture armature part, which is a kind of a-symmetry iron 'ZV' shape work piece that is often used in relay assembly. The key problem is to design the cavity. On the base of modeling the billet and die parts, the FEM software DEFORM-3D is used to simulate the forming process and analyze the potential defects, and gain the best parameters to optimize cavity shape. Based on these results, experiment has been done, and it demonstrated that numerical simulation is effective and the die design is rational.

The effect of heat treatment on the magnetostrictive properties of a (110)-oriented polycrystal Fe83Ga17 alloy was investigated. It was found that the saturation magnetostrictive strain of the quenched Fe83Ga17 alloy exceeded 300 × 10 under a compressive stress of 25 MPa. The results of Neutron diffraction and differential thermal analysis confirmed that slow cooling leads to the change of phase structure which results in the change of magnetostrictive strain. The increase in magnetostrictive strain of the Fe83Ga17 alloy treated by quenching is explained as that the long-range DO3 is suppressed.

"Self-synchronization" is a key concept that constitutes the theory of Network Centric Warfare/Operation (NCW/NCO). But only a brief discussion is available in the classic literature on NCW. Further analysis and extended discussion is made in this paper. Approaches to realize self-synchronization network (SSN) in modeling/simulation domain are introduced, including agent-based framework, domain-specified knowledge modeling and decision-support algorithm. A case was constructed to confirm the idea and evaluate the effectiveness of "self-synchronization". simulation results reveal that self-synchronization has an advantage over other operational modes. At the end of paper, conclusions are drawn and expectation of future works is proposed.
