摘要： The invention provides a process for forging a titanium-based material comprises the steps of: preparing a titanium-based sintered workpiece including at least one of ceramics particles and pores in a total amount of 1% or more by volume, the ceramics particles being thermodynamically stable in a titanium alloy; and heating the workpiece to a forging temperature and forging the same. In the production process, the pores or the ceramics particles inhibit the grain growth during forging. Accordingly, it is possible to carry out the forging at a relatively high temperature at which the titanium-based material exhibits a small resistance to deformation. Moreover, the titanium-based material can maintain an appropriate microstructure even after the forging. Consequently, the impact value and the fatigue strength are inhibited from decreasing.

摘要： When used, a hot extrusion forging die for use in titanium alloy according to the present invention extrusion works a heated titanium alloy-made billet in such a manner as to diameter-reduce the billet. The hot extrusion forging die for use in titanium alloy according to the present invention is equipped with a die member for extrusion working. The die member is made of ceramic. The forging die according to the present invention makes it possible to suppress the sticking of the die member onto an extruded work to thereby make it easy to take out the extruded work. Also, the forging die according to the present invention makes it possible to suppress the seizure of the titanium alloy-made billet, with the result that there can be used a lubricant for which the removing operation is not needed to be done.

摘要： An orifice plate 21 is attached at the tip of an injector 1 to cover a fuel passage hole 18. The orifice plate 21 is provided with a plurality of orifices 24 for allowing fuel having passed through the fuel passage hole 18 to be injected. The orifice plate 21 includes a plate body 23 constructed in layers, and each orifice 24 is constructed of a plurality of holes 27a-27d each formed in each layer of the plate body 23 so that each hole is perpendicular to a surface of the plate body 23, the holes being disposed in communication with each other and with displacements from each other along a line obliquely intersecting the plate body.
