PROBLEM TO BE SOLVED: To provide a casting method, a cast article and a casting system.SOLUTION: The casting method includes providing a base material into a mold, directing a fluid material into the mold, and solidifying the base material and the 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 differs from the second density; the first composition differs from the second composition; or the first density differs from the second density and the first composition differs from the second composition. The cast article includes a first material solidification from the base material, and a second material solidification from the fluid material. The casting system includes a mold for containing a base material and input means, the input means having a flow control feature, for providing a fluid material into the mold containing the base material. 【課題】鋳造方法、鋳造品、及び鋳造システムを提供すること。【解決手段】鋳造方法は、鋳型に母材を供給するステップと、鋳型に流体材料を送るステップと、母材及び流体材料を凝固させて鋳造品を形成するステップとを含む。母材は、第１の密度及び第１の組成を有する。流体材料は、第２の密度及び第２の組成を有する。第１の密度が第２の密度と異なるか、第１の組成が第２の組成と異なるか、或いは第１の密度が第２の密度は異なっているとともに第１の組成が第２の組成と異なる。鋳造品は、母材からの第１の材料凝固と、流体材料からの第２の材料凝固とを含む。鋳造システムは、母材を収容するための鋳型と入力手段とを含み、入力手段は流れ制御特徴を有し、母材を収容する鋳型に流体材料を供給する。【選択図】図１
