摘要： A metallic member forming method capable of achieving both formability of a metallic member and highly strengthening same. Cylindrical metallic member 1 having a hollow space 10 and forming die 3 having a forming face 31 are used. Metallic member 1 is heated up to a temperature range capable of quench-reinforcing (e.g., not less than A1 transformation point). By increasing internal pressure of gas contained in the hollow space 10 of the metallic member 1 a wall 1a of the metallic member 1 is bulged and/or deformed, and the bulged, deformed wall 1a of the metallic member 1 is deformed by bringing it into intimate contact with the forming face 31 of the forming die concurrently with quench-reinforcing it. High strengthening of the metallic member 1 is achieved.

摘要： The invention provides a steel pipe being superior in workability, particularly in bending workability, in which an r-value in the axial direction of the pipe in a portion where melting or transformation of a steel material has occurred during seam welding is as high as comparable to that in a portion where melting or transformation of the steel material has not occurred, and a method of producing the steel pipe. In the high-workability steel pipe, an r-value in the longitudinal direction is not less than 1.2, more preferably not less than 1.6, over an entire area in the circumferential direction, including a seamed portion. The steel pipe is produced by a method comprising the step of performing diameter-reducing rolling on a steel pipe in a temperature range of from 600null C. to Ac3 with a reduction in diameter of not less than 30%, preferably after heating the steel pipe to temperatures of not lower than Ac1, the steel pipe being produced by seam-welding strip steel, or a method further comprising the step of performing heat treatment of holding the rolled steel pipe in a temperature range of from 600null C. to 900null C. for a time of 1 second or longer during cooling subsequent to the diameter-reducing rolling or by reheating the rolled steel pipe after the cooling.

摘要： A method for joining a tube to a member. A tube having a flange is obtained, and a member is obtained. The tube and the member are positioned with the flange contacting the member either directly or indirectly through an intervening joining material. The tube and/or the member are locally heated proximate the contact of the flange and the member without substantially heating the tube and/or the member apart from proximate the contact of the flange and the member. In one example, the local heating is welding, with or without a filler material, such as resistance welding, laser-beam welding or electron-beam welding. In another example, the local heating is brazing. In an additional example, a curable adhesive joining material is placed on the flange and/or the member, wherein the adhesive is located between and directly contacts the flange and the member, and wherein the local heating cures the adhesive.

摘要： An apparatus is disclosed for annealing only a portion of an elongated tubular workpiece. The apparatus includes an elongated tube dimensioned to receive the workpiece so that a first end of the workpiece together with the portion to be annealed is positioned within the tube while a second end of the workpiece extends outwardly from the tube. An induction coil is disposed coaxially around only a portion of the workpiece portion exteriorly of the tube while a source of pressurized nitrogen/hydrogen is fluidly connected to the interior of the tube. In an annealing operation, the tube is filled with hydrogen/nitrogen and the induction coil is energized thus heating only the portion of the workpiece for which annealing is desired. Simultaneously, hydrogen/nitrogen flows through the tube thus cooling the workpiece and maintaining an oxygen-free environment within the tube.

摘要： A brake lining comprises a lining support plate, an underlayer material and a friction lining. The brake lining is clamped between a pressure plate and a holding fixture, which forms a hole matrix and inside of which electrodes are accommodated. A power supply is connected to the electrodes. The adjacent electrodes have different polarities. A current flow is produced between adjacent electrodes as a result of the different polarities. The field lines extend in the shape of an arch. An arrangement of this type permits the friction lining to be scorched. For hardening, a potential gradient can also be applied between the electrodes and the support plate. The current then flows and the entire friction lining is permeated. This results in a homogenous heating of the friction lining. The invention enables an efficient hardening of the friction lining. It is also possible to conduct a hardening and scorching simultaneously. The invention also enables the friction lining to be pressed during the heat treatment.
