[103] Quantitative analysis of non-uniform deformation in semisolid Al-Cu alloys under compression process

*Taisuke NUMATA1, Taka Narumi2, Ryoji Katsube2, Hideyuki Yasuda2 (1. Kyoto univ. (master), 2. Kyoto univ.)

Keywords:鋳造、凝固、鋳造欠陥、固液共存状態、変形

Al-Cu合金の固液共存体の圧縮変形過程を4D-CTを用いてその場観察した.変形過程で試料内部に割れが形成した.また,デジタルボリューム相関法を用い,せん断変形の局在化と局所的な見かけ体積の膨張を明らかにした.
