Abstract: A method is disclosed for producing components from an austenitic lightweight steel which is metastable in its initial state, by forming of a sheet, a circuit board or a pipe in one or more steps, exhibiting a temperature-dependent TRIP and/or TWIP effect during forming. To obtain a component with, in particular, high toughness, the forming is carried out at a temperature above room temperature, at 40 to 160° C., which avoids the TRIP/TWIP effect, and to achieve in particular high component strength, the forming is carried out at a temperature below room temperature, at −65 to 0° C., which enhances the TRIP/TWIP effect.

Abstract: A blast treatment method for blasting an object includes: a step in which an explosive is detonated inside a pressure vessel (30) which has an elasto-plastic metal, thereby imparting to the pressure vessel (30) an initial load wherein the primary and secondary stress generated in at least a portion of the pressure vessel becomes high enough to be in a plastic region exceeding the elastic region, thereby generating a shakedown state in the pressure vessel (30); and a subsequent step in which a treatment explosive (50) is detonated within the pressure vessel (30), thereby blasting the object (10).

Abstract: In a method of making a metallic thin wire (1), one single metallic thin wire (2) is prepared to have a predetermined length with a middle portion of the one single metallic thin wire (2) as a fixed portion. Front and rear half portions of the one single metallic thin wire (2) are twisted with the front and rear portions being symmetrically located at both sides of the fixed portion, while at the same time, applying a tensile weight (W) to the front and rear half portions in the lengthwise direction. The one single metallic thin wire (2) is processed with a heat treatment to remove a residual stress from the one single metallic thin wire (2). Otherwise, the front and rear portions of the one single metallic thin wire (2) is primarily and secondarily twisted alternately under the tensile weight (W) applied in the lengthwise direction. This provides the metallic thin wire (1) with a high rotation-following capability and high torque transmissibility, thus enabling artisans to usefully apply the metallic thin wire (1) to a main wire component (25) of a medical tool and equipment.
