    摘要： A process for obtaining a mechanical component by joining a first metallic material and a second metallic material. The process comprises: (A) putting the first material and the second material in contact with each other, (B) fixating a sheet metal element onto the first material to at least partly enclosing the second material and so that the sheet metal element is at least partly in contact with the second material. The sheet metal element comprises carbon, joining the first material and the second material by diffusion welding. The carbon activity of the second material Ca2 and the carbon activity of the sheet metal element Cam at the temperature of joining fulfills a relation Ca2≦Cam.

    摘要： Powder metallurgy products of high tensile strength are formed in a pore-free state by a novel process which entirely avoids the use of canisters. An open-pore specimen is purged with depurative gas, backfilled with a reactive gas and, while still immersed in the reactive gas, compressed isostatically to an extent necessary to close the pores. The specimen may then be compressed to full density without the need for either high vacuum or a depurative or reactive gas atmosphere.

    摘要： A process for making a workpiece suitable for being hot worked to produce a wrought metal poduct is described. Aluminum alloy powder is cold compacted and then heated in an inert environment to provide a sinter-sealed shape. The resultant workpiece may then be subjected to conventional processing to produce the desired wrought product.

    摘要： This invention relates to a process and an apparatus for converting lump-size material, particularly scrap, of titanium metal or its alloys, preferably of low oxygen content, into powder-form material, which is useable for forming in a powder-metallurgical way pressings and workpieces, wherein the lump-size material is highly embrittled by charging with hydrogen, the embrittled material is size-reduced by means of size-reducing machines, particularly impeller breakers, impact mills, hammer mills, impact hammer mills or hammer breakers, the size-reduced brittle material preferably having a particle size of less than about 10 mm and more particularly of less than about 6 mm is further size-reduced by means of at least one jet stream by impinging on a baffle plate or an anvil or on the particles of at least one other jet stream for the purpose of conversion into the powder-form material, and the powder-form material is converted into the ductile state by heating, preferably at temperatures above 450.degree. C. and more particularly at temperatures above 700.degree. C., preferably under reduced pressure and more particularly under a reduced pressure of the order of 10.sup.-1 Torr or lower.

    摘要： Heat treating a product material of prealloyed powders after shaping by superplastic deformation restores the ability of the material to resist deformation at high temperatures. Heat treating is accomplished by heating to a temperature between the solidus and liquidus with the application of isostatic pressure to close any voids. This pressure may be simultaneously applied while the material is at the heat treating temperature. The pressure may also be applied when the material cools to a temperature between that at which it is shaped and the solidus.
