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.

The casting insert wall has a wall thickness which can be defined as a normal distance between a point of the casting insert wall which faces the cavity and a point on an outer surface of the casting insert wall. The wall thickness is, at least in sections, less than 25% of a diameter of the casting insert.

Abstract: Methods are provided for producing alloy forms from alloys containing one or more extremely reactive elements and for fabricating a component therefrom. The fabricating method comprises substantially removing a reactive gas from the fabrication environment. An alloy form of the alloy is formed. The alloy form is formed by melting the alloy or by melting one or more base elements of the alloy to produce a molten liquid and introducing the one or more extremely reactive elements into the molten liquid. The molten alloy is shaped into the alloy form. The component is formed from the alloy form. If the one or more extremely reactive elements are introduced into the molten liquid, such introduction occurs just prior to the shaping step.

Abstract: This invention presents a method for manufacturing sintered and carburized porous stainless steel parts, comprising steps of: sintering stainless steel powders to obtain a porous sintered stainless steel, wherein the porous sintered stainless steel comprises a three dimensional network skeleton structure with a large number of interconnected pore channels; and carburizing the porous sintered stainless steel by a non-halogenated carbon-bearing gas, wherein the porous sintered stainless steel being maintained at a carburizing temperature below 600° C. such that carbon atoms can be implanted into the porous sintered stainless steel and converts a surface portion of the skeleton structure, that is in contact with the carbon-bearing gas in the interconnected pore channels, into a carburized layer. A carburized layer is formed and spread over a skeleton structure of the sintered porous body. Thereby, the strength, surface hardness, and core hardness of the sintered body are significantly increased.
