摘要： PURPOSE:To enable strongly the joining of both joining members by existing super plastic alloy on the part where two joining members to be subjected to solid phase bonding are opposing and by applying a big plastic deformation on the part opposing to the joining face of this super plastic alloy. CONSTITUTION:Two joining members 1A, 1B are inserted into the die 2 having taper part 2a on the way, opposing each other on the taper part 2a the joining face 3 to be joined and supporting the rear part by pistons 4, 5 respectively. The interface of the joined face 3 performs plastic deformation with enlarging the area when a load is applied in the direction to compress the joining member 1A, 1B by piston 4 and a new face is caused on the interface. The joining members 1A, 1B return to the original shape once again when it is unloaded by returning the piston 4 to the original position. Further new face is caused with shrinking the interface at this returning time. The crystal grain having high activity appears on the joining interface by repeating such operations and two joining members 1A, 1B are strongly joined.

摘要： PURPOSE:To join hafnium and a zirconium-base alloy to a satisfactory composite material by combining the zirconium-base alloy to the surface of the hanium by press welding or thermal spraying and joining diffusively both metals in the temp. region where the beta phase of the zirconium-base alloy exists then cooling quickly the joined material. CONSTITUTION:A zirconium-base alloy plate is combined to the surface of a hafnium rod by presswelding or thermal spraying to form the film of said alloy thereon in the stage for coating the zirconium-base alloy on the surface of the hafnium rod for a nuclear reactor control rod to suppress deterioration of the hafnium and to prevent liberation of oxide. The coated rod is subjected to diffusion bonding at about >=880 deg.C at which the zirconium-base alloy forms body centered cubic lattice and thereafter the rod is cooled quickly so that the beta phase remains down to an ordinary temp. on account of supercooling. The difference in volumetric expansion is decreased and the strain of the diffused surface is decreased, by which satisfactory joining is accomplished.

摘要： PURPOSE:To manufacture a clad metal having a covering metal of uniform thickness, by lowering the surface roughness of inner peripheral face of a covering tube metal to below specified value. CONSTITUTION:A covering tube metal larger in diameter than a base metal is fitted to the base metal. These are pressed and plastic deformed to flatten them and a clad metal having closely contacted outer peripheral face of the base metal and inner peripheral face of the covering tube is manufactured. Surface roughness of outer peripheral face of ordinary copper base metal and inner peripheral face of stainless steel tube is about 5-10mu. However, surface roughness of inner peripheral face of the covering tube metal is made specially less than 3mu to lower frictional force generated between the surface of the base metal and inner peripheral face of the covering tube metal. By this way, their fluidity is increased and the thickness of covering tube metal becomes uniform.

摘要： PURPOSE:To manufacture a clad bar material free from cracking of covering material and opening between covering metal and base metal, by determining sectional dimension of the base metal, inner diameter of the covering metal and formed thickness to make average percentage of elongation in the direction of flat of covering metal after forming within a specified range. CONSTITUTION:A bar base metal 1 made of electric conductive metal or alloy having circular sectional form is inserted into a tubular covering metal 2 made of anti-corrosion metal or alloy, and placed between dies 4, 5 and pressed. Then, the base metal fills up inside of the covering material 2, but the covering material is little elongated at this point of time. When pressed further, R part 2b of the covering metal 2 is flattened. At the same time, flat parts 2a are elongated and thickness is reduced, and a desired clad bar metal having flat parts 2a' is obtained. In this case, sectional dimension of the base metal 1, inner diameter of the covering metal and formed thickness are determined to make average percentage of elongation more than 5% and less than allowable percentage of elongation of the material. Little elongation occurs in R part 2b, and initial thickness is retained.

摘要： A method of bonding two crystals together is disclosed. A bond enhancing material such as chromium (Cr) is vapor deposited on one crystal, and on this is vapor deposited a noble metal such as gold (Au). On the other crystal a low melting point metal such as tin (Sn) or indium (In) is vapor deposited. In the case of In this can either be directly on the crystal or on a layer of bond enhancing material; in the case of Sn this must be on a bond enhancing material. On top of the low melting point metal a layer of the same noble metal is deposited to prevent oxidation thereof. The noble metal layers are brought into contact with each other in vacuum or inert atmosphere and pressure applied thereto at a temperature of 100 DEG C to 150 DEG C in the case of In and 100 DEG C to 200 DEG C in the case of Sn. The low melting point metal will diffuse into the noble metals and across the interface causing a bond to form by elimination of the boundary between the crystals.

摘要： PURPOSE: To stabilize the quality of joined surfaces by diffusion welding by hermetically mounting caps to both ends of an outside pipe, putting the joined part of the outside pipe and an inside pipe in a vacuum or inert atmosphere and heating these in an atmospheric furnace.
CONSTITUTION: Caps 6, 6' are mounted to both ends of an outside pipe 1 which is an object to be welded assembled with the outside pipe 1, an inside pipe 2, and a metallic round bar 3, thereby hermetically sealing the inside of the pipe 1. An exhaust pipe 7 is provided to the one cap 6' to evacuate the inside and to put only the joined surfaces of the pipe 1 and the pipe 2 in a vacuum or inert atmosphere. When this object to be welded is heated to the correct temp. for diffusion welding in a heating furnace 12 in the atmospheric air, the pipe 2 is pressed to the pipe 1 by the expansion of the bar 3 having a coefft. of thermal expansion larger than that of the pie 1 and the pipe 2, whereby a clad pipe or the like is manufactured.
