摘要： A method for producing a counter-form (20) for manufacturing a part having a complex shape (24) by pressure sintering densification. The counter-form (20) is formed from successive layers produced by numerically-controlled three-dimensional (3D) additive printing according to the following steps: numerically recording a three-dimensional negative of the part to be produced (24) in a control unit of a three-dimensional additive printing system in order to constitute the positive form of the counter-form to be produced; producing the counter-form (20) using a 3D additive printing technique. The part having a complex shape (24d) is then manufactured by pressure sintering, then separated from the counter-form which is also sintered (20).

Si, according to a weight fraction from 4% to 20%;
Fe, according to a weight fraction from 2% to 15%.

摘要： A method of joining first and second materials. The first material is a metal, a ceramic, or a composite material comprising carbon fibre, and the second material is a metal. The first material has a coefficient of thermal expansion, CTE, which is higher than a CTE of the second material. An interlayer is formed, having a high thermal expansion surface and a low thermal expansion surface. The CTE of the interlayer varies through its depth between the CTE of the first material and the CTE of the second material. The interlayer has four average coefficients of thermal expansion, aCTE, defined such that each aCTE is the average coefficient of thermal expansion over one quarter of the thickness of the interlayer. Each aCTE is less than the previous aCTE, where the first aCTE is next to the high thermal expansion surface. Either: the difference between the first and second aCTE is greater than the difference between the second and third aCTE, and the difference between the second and third aCTE is greater than the difference between the third and fourth aCTE; or the difference between the second and third aCTE is greater than both the difference between the first and second aCTE and the difference between the third and fourth aCTE.

摘要： A method of modifying the physical characteristics of a base titanium alloy article previously manufactured through a selective melting process is disclosed. The method includes introducing hydrogen through a thermohydrogen process to the base titanium alloy article, the resulting titanium alloy article exhibiting an isotropic and fine grained equiaxed microstructure. The thermohydrogen process may include introducing hydrogen into the base titanium alloy article to lower the beta transus temperature, heating the base titanium article above the lowered beta transus temperature to form hydrided beta, lowering the temperature of the base titanium alloy article to affect a eutectoid transformation, and dehydriding the base titanium alloy article via vacuum heating. The base titanium alloy article may have an elevated oxygen content and/or hydrogen may be introduced at 0.4 weight percent or greater.
