摘要： The disclosure provides methods of making iron-based alloys, as well as resulting alloys. An iron-based alloy containing a small amount of nickel (e.g., 0.5 to 2.0 wt %) is annealed and machined. The alloy is sufficiently ductile to reduce the likelihood of cracking, while not sufficiently high to result in a hardened alloy. After the alloy is shaped, the alloy is hardened by nitriding.

摘要： An object of the present invention is to provide a metal elastic element which is suitable for sensing or the like of a fluid pressure change and exhibits favorable resilience even in the case of receiving a sudden pressure change, and also provide a diaphragm using the same. A metal elastic element of the present invention is composed of a two-phase stainless steel having a γ-phase and an α-phase, wherein the area ratio of the γ-phase is 40% or less, and the two-phase structure is a marble-like metal structure. In the invention, it is preferred that the element has a fiber texture in which γ and α are preferentially oriented parallel to the thickness direction.

摘要： Provides is a method of producing a grain oriented electrical steel sheet by heating a steel slab having a predetermined composition, then subjecting the slab to hot rolling to obtain a hot rolled sheet, then optionally subjecting the hot rolled sheet to hot band annealing and subsequent cold rolling once, or twice or more with intermediate annealing performed therebetween to obtain a cold rolled sheet with final sheet thickness, then subjecting the cold rolled sheet to primary recrystallization annealing and subsequent secondary recrystallization annealing, in which the aging index AI of the steel sheet before final cold rolling is set to 70 MPa or less to effectively grow Goss-oriented grains to thereby obtain a grain-oriented electrical steel sheet with good magnetic properties, without the restriction of containing a relatively large amount of C.
