摘要： A method for producing a stainless steel diffusion-bonded product is aimed for providing a stainless steel material diffusion-bonded product having excellent reliability of the bonded portion by using a "direct method" which can be performed with a work load equivalent to that of a conventional insert material insertion method, and the method includes directly contacting stainless steel materials with each other to unify the materials together by diffusion bonding, and in the method, at least one of the stainless steel materials to be contacted is dual-phase steel having an austenite transformation starting temperature Ac 1 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, and the 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.

摘要： [Object] To provide a joining method for dissimilar metals which are magnesium alloy and steel and difficult to be metallurgically directly joined to each other while oxide film is present at a joining surface. [Solving means] In order to join magnesium alloy material 1 and steel plate 2 to each other, a galvanized steel plate to which Zn-Al-Mg alloy plating (a third material) is applied is used as the steel plate 2. When joining is made, ternary eutectic melting of Al-Mg-Zn is caused, so that it is discharged together with oxide film 1f and impurities from the joining interface while Al-Mg intermetallic compound such as Al 3 Mg 2 and Fe-Al intermetallic compound such as FeAl 3 are formed, thereby joining the newly generated surfaces of the magnesium alloy material 1 and the steel plate 2 to each other through a compound layer 3 containing these intermetallic compounds.

摘要： Provided is a friction stir welding method for steel sheets comprising: inserting a rotating tool into an unwelded portion where two or more steel sheets are overlapped or butted together; moving the rotating tool along portions to be welded while rotating the tool, so that a softened portion is formed in the steel sheets by friction heat generated between the rotating tool and the steel sheets, and the steel sheets are welded together by utilizing a plastic flow generated by the softened portion being stirred; and preheating the unwelded portion before welding by the rotating tool, wherein the preheating of the unwelded portion is performed by a pair of heating devices disposed over and under the unwelded portion and ahead of the rotating tool in the advancing direction to enable high speed welding without the risk of generation of welding defects and damages to the welding tool.
