Abstract: A rod material made of Ti alloy has a larger diameter portion at the end, which is joined with the end of material made of TinullAl intermetallic compound, by friction welding, to form a poppet valve for an internal combustion engine. Instead of providing such larger diameter portion, the end of the material made of TinullAl intermetallic compound may be heated to facilitate joining.

Abstract: The present invention relates to a method for manufacturing a sintered body of carbonitride alloy with titanium as the main component and cobalt as the binder phase and which does not have any compositional gradients or center porosity concentration after sintering. This is achieved by processing the material in a specific manner to obtain a lower melting point of the liquid phase in the interior of the body than in the surface while balancing the gas atmosphere outside the body with the alloy composition during all stages of the liquid phase sintering.

Abstract: A method and apparatus for manufacturing a shaped precision article from molten metal or molten metal alloy wherein a gas atomised stream of molten metal or molten metal alloy is directed at a collecting surface to form a coherent deposit, the stream being cooled in flight by the atomising gas, which is at ambient, preferably room temperature, sufficient heat being extracted by the relatively cold atomising gas from the stream of molten metal in flight such that formation of the coherent deposit is independent or substantially independent of the thermal properties and temperature of the collecting surface, provided the temperature of the collecting surface is below the melting point of the metal or metal alloy being sprayed; and the deposit is worked as by a die to form the precision metal or metal alloy article.

Abstract: The present disclosure relates to the technical field of material processing, and particularly provides a preparation process for a golf head with dual metal components. The molded tungsten alloy injection blank is embedded into a stainless steel injection molded mould, the stainless steel feed and the tungsten alloy injection blank are subjected to injection molding to obtain an integrated injection blank subjected to in-mould injection molding, and the golf head with dual metal components is prepared by degreasing and sintering. The preparation process of the present disclosure is applied to golf heads required for counterweight assembling, is completed by using one-time degreasing and sintering process after injection molding of dual metals so as to break through the limitation of a metal injection molding (MIM) technology that can only produce one metal part once, and can be used for one-time molding of stainless steel and tungsten alloy metal parts.
