    Abstract: Improved assembly and methods for manufacturing a three-dimensional object are described. The assembly includes a crucible for holding molten metal, an orifice disposed in the bottom of the crucible through which a jet of molten metal can flow towards a movable substrate, and a mechanically oscillating member immersed in the molten metal for controlling the flow of molten metal through the orifice and for breaking the flow of molten metal into the sequence of molten metal drops. As the drops land on the movable substrate, a three-dimensional object is built up. Continuously variable diameter or controllable planar jets may be used as the orifices. In forming drops from the output of a planar jet, the jet is first broken up by the oscillating member into horizontal cylindrical ligaments and the ligaments are then broken up into drops by acoustic energy applied by audio loudspeakers adjacent the falling ligaments. The assembly and methods are useful in the fields of rapid prototyping and materials processing.

    Abstract: There is provided a high-strength steel plate having acicular ferrite and bainite as a main microstructure and an austenite/martensite (M & A) as a second phase under the control of a cooling rate above the austenite transformation temperature. The high-strength steel plate comprises: carbon (C): 0.03 to 0.10 wt %, silicon (Si): 0.1 to 0.4 wt %, manganese (Mn): 1.8 wt % or less, nickel (Ni): 1.0 wt % or less, titanium (Ti): 0.005 to 0.03 wt %, niobium (Nb): 0.02 to 0.10 wt %, aluminum (Al): 0.01 to 0.05 wt %, calcium (Ca): 0.006 wt % or less, nitrogen (N): 0.001 to 0.006 wt %, phosphorus (P): 0.02 wt % or less, sulfur (S): 0.005 wt % or less, and the balance of iron (Fe) and other inevitable impurities. The method for manufacturing a high-strength steel plate may be useful to economically and effectively manufacture a high strength steel, which is able to secure excellent properties such as high strength and high toughness since the acicular ferrite and bainite may be effectively formed without adding expensive elements such as molybdenum (Mo).
