摘要： Disclosed in a jig unit for heat treatment of a metal workpiece such as, e.g., a hollow hemispherical work as a part of a rocket motor case. The jig unit includes a constraining templet member which is made of a metal having a greater coefficient of expansion than the material of the work and has an outer surface shaped correspondingly to the inner surface of the workpiece. A base of the jig unit holds the templet member and the workpiece such that the outer surface of the templet member is slightly spaced from the inner surface of the workpiece. The work is heated together with the templet member while introducing an inactive gas into the gap between the workpiece and the templet member. By thermal expansion the templet member comes into close contact with the inner surface of the workpiece and serves as a constraining means, whereby strains in the work are remedied. Cooling of the heated workpiece is carried out while the templet member is still in close contact with the inner surface of the workpiece.

摘要： A method of welding opposite end surfaces of two titanium alloy parts kept in alignment by a high energy-density welding process such as electron beam welding, laser beam welding or TIG arc welding, characterized by closely interposing an insert member of either practically pure titanium or Ti-Al binary alloy containing up to 3 Wt % of Al. Owing to thorough alloying of the inserted titanium with the constituents of the fused base metal, the weld metal in a weld joint obtained by this method is sufficiently high in both strength and toughness. By an optional postwelding heat treatment, the strength of the weld metal can further be enhanced.

摘要： In a vacuum laser irradiating apparatus disposed between a laser generator and a vacuum vessel in which an object to be irradiated with a laser beam is placed, an outer window plate is airtightly fixed to the outer opening of the apparatus body to maintain the internal cavity of the apparatus body under a vacuum and to pass the laser beam therethrough. This outer window plate is reinforced so as not to be distorted due to pressure difference between an inside vacuum of the apparatus body and an outside atmospheric pressure. This is because the outer window plate is made of an expensive pure monocrystalline material and therefore it is preferably to reduce the thickness thereof for material cost reduction.

摘要： The invention relates to a method of producing a bowl-like metal article, e.g. a half of a spherical rocket motor case made of a titanium alloy, by first shaping a flat blank into a bowl-like shape by a press forming operation and subsequently making heat treatment of the bowl-like work. Following the press forming operation, the shape of the bowl-like work is corrected by spinning. At the heat treatment a templet member is used to keep the bowl-like work in a restrained state so as to correct possible irregular straining and distortion of the work. Preferably the templet is a bowl-like member designed and disposed such that its outer surface comes into close contact with the inner surface of the bowl-like work by thermal expansion at the heat treatment. Both the thickness of the blank and the amount of machining on the heat-treated work can be reduced.

摘要： In regard to sheet metals of inferior formability as typified by titanium alloys, each end face of a blank is covered with a cover plate of a metal which surpasses the blank material in formability, and the covered blank is subjected to a usual shaping operation in which the steps of heating the blank and pressing the heated blank are cycled a plurality of times, so that the blank can be protected against contamination attributable to exposure of the hot blank to the atmosphere and hence saved from having a large margin in the thickness thereof. A lubricant layer is preferably formed between the blank and each cover plate for a further improvement on the formability.
