    Abstract: A method of manufacturing hollow objects of complex shapes with elaborated internal cavities and channels in order to reduce the weight and/or for highly effective cooling systems, for example gas turbine blades, powerful laser optic systems, combustion chambers, etc. In itself the method includes the preparation of the framework to assure the desired constructional strength with grooves and/or pockets on the surface, which correspond to the internal dimensions of the finished metal product; filling the grooves and pockets with easily removed material; forming a multilayered outer coating shell of the necessary thickness by using a cathode-ray method with preliminary spraying of the framework with a thin layer of easily melted metal or material able to develop eutectic low-temperature with the sprayed material of the outer shell; and with a subsequent thermoplastic treatment to obtain a shell with a given stable and homogeneous structure and a multilayered or gradually varying composition; removal of the easily removed filler material by sublimation at the time of the thermal treatment. Chlorides, fluorides and/or their mixtures can be used as the easily removed material, with active and inactive additives to improve the mechanical and thermal properties of the mixtures, and modifying the structures and the properties of the internal surfaces with the spraying process and the thermoplastic treatment.

    Abstract: A method of bonding a titanium article to another metal article using a superplastic interlayer is disclosed. A fine-grain titanium alloy interlayer is provided between faying surfaces of the articles to be bonded. The interlayer has an alpha-beta microstructure and an average grain size of less than about 1-3 microns (.001-.003 mm) in at least one plane. The articles to joined and the interlayer are heated to between 1000 DEG F (538 DEG C) and 1500 DEG F (816 DEG C). A sufficiently large compressive force is then applied to the articles to cause superplastic deformation of the interlayer and bonding of the articles.
