AC4CHアルミニウム合金の切欠引張特性 Notched Tensile Properties of AC4CH Aluminum Alloy Casting
The notched tensile properties of AC4CH alloy, which was often used for structual parts were investigated. The following results were obtained. The notch coefficient was less than 1 and notch-sensitivity was negative. The notch coefficient increased slightly as defects increased. The notched yield ratio, which corresponded to fracture toughness, decreased with increasing 0.2% proof stress, while the notched yield ratio increased with decreasing Fe content.
