摘要： PROBLEM TO BE SOLVED: To provide a metal carrer catalyst for cleaning exhaust gas, the catalytic performance of which is restrained from being deteriorated owing to the oxidation and corrosion of a metallic carrier. SOLUTION: This metal carrer catalyst is provided with the metallic carrier consisting of stainless steel and a catalyst layer deposited on the surface of the metallic carrier. A surface layer having excellent oxidation resistance is formed on the surface of the metallic carrier by imparting mechanical energy to the metallic carrier in the presence of a fine particle. As a result, the cleaning performance of this metal-supported catalyst can be kept for a long time since a catalytic metal in the catalyst layer is not brought into direct contact with the metallic carrier.

摘要： PROBLEM TO BE SOLVED: To provide a method of joining Ti-Al-base alloy members which are capable of satisfactorily brazing these members even in the atmosphere air while suppressing the hike of a cost.
SOLUTION: A brazing filler metal containing at least either of silicon and chromium as a main component is arranged at the joining boundary between the first member 1 and the second member 2. The first member 1 and the second member 2 are brazed in the atmosphere air by loading the surface pressure of ≥0.1 MPa and below the yield stress of the first member 1 and the second member 2 to the joining boundary, heating the joining boundary to a brazing temperature region in the atmosphere air and specifying the time for holding the members in the brazing temperature region to 15 to 40 seconds.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method where the hollow part of a hollow member is easily formed of a titanium-based composite material by cutting work.
SOLUTION: The manufacturing method for the hollow member made of a titanium-based composite material comprises the following processes: a forging process for forging the forging material (8) that has an outer peripheral layer (81) made of a titanium-based composite material whose matrix, in which reinforced particles are dispersed, is mainly constituted of titanium and that has an inner peripheral layer (82) which is arranged inside the outer peripheral layer and which is made of a free-cutting titanium material having more excellent machinability than the titanium-based composite material; and a hollow-part forming process for forming a hollow part (101) by cutting the inner peripheral layer of the forging material that is obtained from the forging process. Since the inner peripheral layer is made of the free-cutting titanium material, the hollow part is easily formed by cutting.
