摘要： The present invention provides a leaf spring material superior in mechanical characteristics and a manufacturing method of the leaf spring material capable of reliably achieving the same, utilizing induction hardening. The manufacturing method of the leaf spring material comprises the steps of imparting tensile stress on a first surface along the longitudinal direction of the first surface and compressive stress on a second surface along the longitudinal direction of the second surface of a substantially strip-shaped steel plate, and subjecting the first surface to induction hardening. With this induction hardening, an induction-hardened structure having a higher average hardness than that of a parent material structure in the vicinity of the second surface and comprising martensite and finely and evenly dispersed austenite is imparted on a surface layer in the vicinity of the first surface.

摘要： An article essentially consisting of one or more of Ti-Al intermetallic compounds is fabricated so as to have a volume ratio of voids of 0.2 to 3.5% and a maximum size of voids less than 50 .mu.m, by preparing a mixture of materials selected from a group consisting of Ti, Ti alloys, Al, Al alloys, and Ti-Al compounds, having a composition suitable for forming a desired Ti-Al intermetallic compound, and heating the mixture so that the mixture may be sintered. Typically, the temperature and pressure for the heating or sintering process, and the particle size of the material are appropriately selected so that a desired porosity and a desired range of void sizes may be obtained. The mechanical strength of the article according to the present invention is not only improved (as compared to the conventional Ti-Al intermetallic compounds) but is highly predictable, or, in other words, highly reliable. The fabrication costs can be reduced because the fabrication process involves only relatively low temperatures when simultaneously pressing and heating the article being formed. Furthermore, during the process of fabrication, such an article may have a highly favorable workability (as compared to the prior art) so that a final shape can be given to the article without involving any undue difficulty.
摘要翻译：通过制备基本上由一种或多种Ti-Al金属间化合物组成的制品，通过制备选自以下的材料的混合物，制成空隙的体积比为0.2-3.5％，孔的最大尺寸小于50μm 由Ti，Ti合金，Al，Al合金和Ti-Al化合物组成的组合物，其具有适于形成期望的Ti-Al金属间化合物的组合物，并加热混合物以使混合物可以烧结。通常，适当地选择用于加热或烧结工艺的温度和压力以及材料的粒度，使得可以获得期望的孔隙率和期望的空隙尺寸范围。根据本发明的制品的机械强度不仅改善（与常规的Ti-Al金属间化合物相比），而且是高度可预测的，或者换句话说，高可靠性。制造成本可以降低，因为当同时压制和加热所形成的制品时，制造工艺仅涉及相对较低的温度。此外，在制造过程中，这样的制品可能具有非常好的可加工性（与现有技术相比），使得可以对制品给予最终形状而不会引起任何不适当的困难。
