摘要： A damage evaluation method and apparatus of a metal material which is capable of determining whether a flaw in the metal sample is originated by the creep damage or in the manufacturing process, and also capable of estimating a remaining life of the metal component. The damage evaluation method of a metal material by the present invention is a method for evaluating a flaw in the metal sample comprising the steps of mounting onto a metal surface including an internal flaw and on both sides of the flaw a transmitting probe for transmitting an ultrasonic waves and a receiving probe for receiving the ultrasonic waves, transmitting the ultrasonic waves towards the internal flaw and receiving the diffracted wave from the flaw for determining whether or not a flaw is present in the metal, based on the analysis of the distribution of the diffracted waves and an analysis of the sample as to whether voids (creep voids) are present and, if present, the distribution of the voids.

摘要： PROBLEM TO BE SOLVED: To provide a turbine housing inhibiting occurrence and progress of a crack in a tongue portion without limiting an amount of exhaust gas flowing in the turbine housing. SOLUTION: The turbine housing is provided with an exhaust gas flow path of a circumferential shape in the inside and has the tongue portion separating the exhaust gas flowing into the exhaust gas flow path from the exhaust gas flowed and swirled in the exhaust gas flow path, and a slit is formed in a central area of the tongue portion in a thickness direction perpendicular to the exhaust gas flow and in a direction almost parallel to the exhaust gas flow. The slit is formed over the entire surface in a transverse direction of the tongue portion almost parallel to the exhaust gas flow and has a depth in which thermal stress occurring in the deepest portion ranges from 1/2 to 1/3 of thermal stress occurring in the surface of the tongue portion.

摘要： In order to provide a welding structure of a tube header and tube stubs which successfully improves the durability thereof against creep and fatigue damage of the tube stubs without interposing a component of a different material between the tube header and the tube stubs, i.e. requiring additional components, a welding structure of the present invention comprises: a tube header (2) being made of ferritic heat resisting steel; a plurality of tube stubs (4) which are welded onto an outer surface of the tube header, each of the tube stubs having a bended section, in which the plurality of tube stubs (4) are made of austenite stainless steel, and welded to the tube header (2) by using nickel base alloy as a welding material. Moreover annular chases (10) are respectively formed on the outer surface of the tube header (2) to surround welding portions of the tube header (2); joining portions (14) are formed on an inner side of the annular chases (10); butt grooves are formed by joining surfaces of the tube stubs (4) and the joining portions (14) in a continuous manner and welded by using the nickel base alloy as a welding material, the tube stubs having a diameter substantially same as those of the joining portions.
