Title (EN) HEAT-RESISTANT CASTING
(FR) PIÈCE MOULÉE RÉSISTANTE À LA CHALEUR
(JA) 耐熱鋳物
Abstract:
(EN) Provided is a heat-resistant casting having a shaft-like part. The structure of the region of the shaft-like part that is subjected to plastic processing contains dendrite, and regarding the dendrite, the average value of the angle formed by the vertical direction of the central axis of the shaft-like part and the main axis of the dendrite is within the range of 20°.
(FR) L'invention porte sur une pièce moulée résistante à la chaleur, qui présente une partie en forme de tige. La structure de la zone de la partie en forme de tige, qui est soumise à un traitement plastique, contient une dendrite et, s'agissant de cette dernière, la valeur moyenne de l'angle formé par la direction verticale de l'axe central de la partie en forme de tige et de l'axe principal de la dendrite se situe dans la plage de 20°.
(JA) 軸状部を有する耐熱鋳物であり、前記軸状部の塑性加工される領域における組織はデンドライトを含み、前記デンドライトは、前記軸状部の中心軸の垂直方向とデンドライトの主軸とのなす角度の平均値が20°の範囲内のデンドライトである耐熱鋳物。
