Abstract: The invention relates to a method of forming an article from an alloy, such as a tin-containing alloy or titanium-containing alloy. Elemental metal powders of metal constituents of the alloy are injected into a pre-heated die and pressure is applied to form a green part. The green part is then alloyed at a predetermined temperature for a pre-determined time period to form the article. The invention also relates to an article formed by such a method.

Abstract: Metal-metal or metal-ceramic/carbide composite materials are fabricated by combination of powder injection molding and infiltration. This is achieved by first forming a composite system having a matrix component and an infiltrant layer. The matrix component is formed from a metal or ceramic/carbide powder, that is of a higher melting point, admixed with a first binder. The infiltrant layer is formed from a metal powder, that is of a lower melting point, admixed with a second binder. The first and second binders are subsequently removed from the composite system during a debinding process. The composite system is then heated in a sintering furnace to coalesce the matrix component into a matrix phase having a network of interconnected pores, and to effect infiltration of the infiltrant layer into these pores to form the composite material of the present invention.

Abstract: A method of bonding two powder components having different shrinkage factors, one of which is metal powder, is disclosed herein. In the preferred method, at step 1.1, each powder component is separately mixed with a powder binder to substantially match the other powder component's shrinkage factor. Then at steps 1.2 to 1.4, the powder component mixtures are compacted in a die set to form a green compact. Next at step 1.5, the green compact is debindered and at step 1.6, the green compact is sintered in a furnace while applying pressure on a surface of the green compact during the sintering process. In this way, the two powder components can be bonded directly without a need for an intermediate gradient zone and a double-layer metal sheet can be thus formed.
Abstract translation: 本文公开了一种将具有不同收缩系数的两种粉末成分接合的方法，其中一种是金属粉末。 在优选的方法中，在步骤1.1中，将每种粉末组分与粉末粘合剂分开混合以与其它粉末组分的收缩因子基本匹配。 然后在步骤1.2至1.4中，粉末组分混合物在模具中压实以形成生坯。 接下来在步骤1.5中，将生坯压坯脱粘，在步骤1.6中，在烧结过程中，在压坯的表面施加压力，将烧结体烧结在炉中。 以这种方式，两个粉末成分可以直接接合而不需要中间梯度区域，因此可以形成双层金属片。
