Abstract: Provided is a method for manufacturing a tubular rotary component from a donut-shaped metal disc, wherein the generation of wrinkles or cracks due to a drawing process can be suppressed. This method for manufacturing a tubular rotary component 100B includes: an intermediate molding step in which the entirety of both surfaces of a donut-shaped metal disc 100 having a prescribed inner diameter D1 and outer diameter D2 are pressed by the respective tapered surfaces of a punch 10A and a die 20A provided with a prescribed taper to carry out bore-expansion drawing, thereby obtaining a frustoconical intermediate molded article 100A; and a final molding step in which the intermediate molded article 100A is pressed by a punch 10B and a die 20B having a desired shape to carry out bore-expansion drawing again, thereby obtaining a tubular rotary component 100B.

Abstract: A plate-type heat exchanger may include a housing. The housing may include a plurality of rectangular plate-like components that are box-like components each having the same shape and having a standing wall section along a peripheral edge. One of the box-like components may be layered on another components reversed in the horizontal direction to form a layered structure having an upper layer component and a lower layer component such that an upper portion of a standing wall section of the lower layer component of the layered structure is fit into a lower portion of a standing wall section of the upper layer component of the layered structure. The angle (?) of the standing wall sections may be ??30°, and at least a portion of a contact region between the upper portion and the lower portion may be joined by solid phase diffusion bonding.

Abstract: A method for producing a stainless steel diffusion-bonded product provides a stainless steel material diffusion-bonded product having excellent reliability of the bonded portion by using a direct method, which includes directly contacting stainless steel materials with each other to unify the materials together by diffusion bonding. At least one of the stainless steel materials to be contacted is dual-phase steel having an austenite transformation starting temperature Ac1 point of 650 to 950° C. during the temperature elevation and having an austenite+ferrite dual-phase temperature region in the range of 880° C. or higher. Diffusion bonding is advanced under conditions such that the contact surface pressure is in the range of 1.0 MPa or less and the heating temperature is in the range of from 880 to 1,080° C. while being accompanied by the movement of grain boundary caused when the ferrite phase in the dual-phase steel undergoes transformation to an austenite phase.

Abstract: Provided is a stainless steel material suitable for diffusion bonded moldings in which diffusion bondability has been further improved without being affected by the extent of surface roughness. The present invention is a stainless steel material for diffusion bonding in which the metal structure before diffusion bonding has a multi-phase structure obtained from two or more of a ferrite phase, a martensite phase and an austenite phase, wherein: the mean crystal grain diameter in the multi-phase structure is not more than 20 ?m; ?max represented by formula (a) is 10-90; and creep elongation when a 1.0 MPa load is applied at 1000° C. for 0.5 his at least 0.2%. ?max=420C?11.5Si+7Mn+23Ni?11.5Cr?12Mo+9Cu?49Ti?47Nb?52Al+470N+189 . . . Formula (a) The element notations in formula (a) represent the contents (mass %) of the respective elements.
