摘要： The present invention provides cast high-carbon steel having high strength and plasticity and a method for its formation. In the method, forming during cooling from the melting point through temperature control results in a structure having small size cementite grains supported in a plastic matrix. Alloys other than high-carbon steel, including nickel, titanium, zirconium, and aluminum, can also be produced by the process.

摘要： Crawler belt bushings and heir producing methods, with which productivity and cost performance can be improved over the carburization treatment and the induction hardening treatment. After a workpiece made from steel is heated from its outer circumferential surface such that at least the surface temperature of the inner circumferential surface of the workpiece is raised to a quenching temperature, a series of quenching operation is performed to form quench hardened layers which extend toward the core from the inner and outer circumferential surfaces respectively and a soft, imperfectly hardened layer between these quench hardened layers. The quenching operation comprises: cooling the workpiece from the inner circumferential surface; cooling the workpiece from the inner circumferential surface while heating from the outer circumferential surface; and cooling the workpiece from the outer circumferential surface.

摘要： A steel workpiece maintained at a specified quenching temperature is rapidly cooled to a temperature just above the martensite transformation start point (Ms point) by being immersed in a high-temperature quenching oil. Thereafter, the steel workpiece is taken out of the high-temperature quenching oil so as to be soaked by the heat possessed by the steel workpiece and subsequently cooled by being immersed in the high-temperature quenching oil. Through these processes, a temperature difference between steel workpieces or the portions of a steel workpiece in the martensite transformation stage is reduced, and a cooling speed in a high-temperature region (not lower than about 550° C.) is made to be a slow speed sufficient for restraining a thermal distortion, by which the quenching distortion and quenching variation can be reduced.
摘要翻译：保持在规定的淬火温度的钢制工件通过浸入高温淬火油中而迅速冷却到马氏体相变开始点（Ms点）以上的温度。然后，将钢制工件从高温淬火油中取出，使其被钢制工件所具有的热量浸泡，然后浸渍在高温淬火油中而冷却。通过这些工序，可减少钢制工件之间的温度差或马氏体相变阶段的钢制工件的部分的温度差，使高温区域（不低于约550℃）的冷却速度为缓慢的速度足以抑制热变形，由此可以降低淬火变形和淬火变化。

摘要： According to the method of the present invention, the ball plug is press fit into the counterbored passage of a fuel injector nozzle assembly prior to hardening of the fuel injector nozzle assembly. A core hardening and gas nitriding process is then applied to the assembly, causing the ball plug to expand and the passage diameter to shrink. This results in a greatly increased seal between the ball plug and the passage, and substantial elimination of the gaps experienced therebetween in prior art fuel injector nozzle assemblies.

摘要： A method of manufacturing a sliding component comprising a main body made of a non-carburized heat-hardened steel and a member adapted to form at least one sliding face of sliding faces of the sliding component and heat-joined to the main body, in which the steel-made main body is heat-hardened before heat-joining to the member and the heat-joining between the main body made of the heat-hardened steel and the member is conducted at a lower temperature than the temperature at which the heat-hardened main body has been heat-hardened. The sliding component is superior in hardness and abrasion resistance and is readily manufactured at a reduced cost.
