Embodiment Construction

[0045] An exemplary casting method, casting article, and casting system are provided. Embodiments of the present disclosure have increased fatigue resistance, increased oxidation resistance, reduced creep and reduced corrosion, improved weldability compared to methods and products that do not utilize one or more features disclosed herein , or a combination of them.

[0046] see figure 1 , the casting method 100 includes providing a base material 101 having a first density and a first composition (step 102). In one embodiment, base material 101 is directed into mold 110 . Fluid material 103 having a second density and a second composition is directed into mold 110 (step 104). Method 100 includes solidifying (step 106 ) base material 101 and fluid material 103 to form cast article 109 .

[0047] The base material 101 is, for example, any suitable material capable of solidifying after melting or from a molten state. Fluid material 103 is any suitable material capable of flow...

Abstract

The invention relates to a casting method, a casting product and a casting system. A casting method, casting product and casting system are disclosed. The casting method includes providing a base material in a mold, introducing a fluid material into the mold, and solidifying the base material and fluid material to form a cast article. The base material has a first density and a first composition. The fluid material has a second density and a second composition. The first density is different from the second density, the first composition is different from the second composition, or the first density is different from the second density and the first composition is different from the second composition. The cast article includes a first solidification of material derived from a base material, and a second solidification of material derived from a fluid material. The casting system includes a mold for containing a base material, and an input configuration having a flow control feature for directing a fluid material into the mold containing the base material.

Description

technical field [0001] The present invention is directed to a method of manufacture and the resulting article. More specifically, the invention is directed to casting methods, casting articles and casting systems. Background technique [0002] Various articles are assembled from more than one material to form multiple parts of the article. In general, such articles are formed by joining a first material to a second material using joining techniques such as welding, bonding, fusing, soldering, brazing, or combinations thereof. Such techniques suffer from various drawbacks. For example, such techniques may have limited applicability to alloys, may be subject to fatigue, may delaminate, or combinations thereof. [0003] Articles formed from the combined alloys are commonly used in power generation systems, engines, bridges, buildings, wind turbines, and other large structures. Such structures are continuously subjected to increased forces to provide improved efficiency and / ...
