摘要:
A clad system for prevention of intermetallic formation. The clad system includes a first layer, a liner, and a second layer. The liner prevents the formation of intermetallics between the first layer and second layer during processes that may lead to intermetallic formation. The clad system may be bonded together using cold roll bonding and other such processes.

A battery cell connector for use with an external device. In an aspect, the battery cell connector comprises a body with at least three layers, configured to simultaneously provide improved weldability and conductivity. In the same aspect, the battery cell connector comprises a terminal connected to the terminal arm of the body of the cell connector and a voltage transmitting component connected to said terminal, wherein the voltage transmitting component is configured to connect to an external device on the opposing end.

A method of forming an article includes forming a layer of a mixture of at least two distinct metal powders selected such that when combined they are chemically in the proportions of a superalloy containing a gamma prime phase, and fusing the powders locally without diffusion to define the shape of a part of the article such that the materials of the distinct metal powders remain substantially chemically segregated forming regions of different chemical composition. The method further includes repeating the forming and fusing until the derived article is formed, and heat treating the finished article such that at least one of the distinct separate materials diffuses to form a gamma prime phase containing superalloy with the other.

摘要:
A FeCrAl alloy for catalytic converter substrates having excellent oxidation resistance and dimension stability at a medium high temperature, e.g. the temperature encountered by catalytic converter substrates in truck diesel engines, without necessary addition of extra Y, Hf, or rare earth elements beyond that inherently present in commercial stainless steel. A roll bonding and diffusion alloying annealing method is used for making such materials with the following two deviated paths. First, material in which layers of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a multilayer composite material. Such composite material is then further rolled to an intermediate foil gauge and then subjected to a thermal reaction to form a resulting uniform solid solution foil material followed by rolling to the final foil thickness. Alternatively, such composite material is further rolled to the final foil thickness and then subjected to a thermal in-situ reaction in the material after a honeycomb-like catalytic converter is made from the foil composite material. Both deviated approaches result in a uniform solid solution foil material.
摘要:
Methods of additive manufacturing a superalloy component are disclosed. In one method a powder bed of superalloy powder is selectively scanned with a focused laser beam in a line-by-line manner; and the spacing between adjacent scan lines is no more than twice the layer thickness being formed. In another method a compressive stress treatment is applied to the surface of the final component prior to separation of said component from the substrate. In a further method a superalloy component is formed on a substrate and the method includes Hot Isostatic Processing of the component wherein the mass of the substrate is reduced prior to the Hot Isostatic Processing. The methods may be combined in a multi-step process.
