| Abstract Scope |
The precipitation hardened commercial CuCrZr (UNS number C18150) alloy with high strength, good electrical and thermal conductivities is used for various critical applications. The data available on CuCrZr alloy in the as-forged and solution treated & aged (TF00 or SAA) condition on the behavior of this material with strain rate for tensile testing to obtain accurate and consistent results in an expeditious manner is scant. Thus, tensile testing was carried out at room temperature over five different strain rates in the range of 4.16X 10-5 s-1 to 1.25X10-3s-1 at ambient temperature. The alloy in the TF00 condition showed recrystallized structure with annealing twins and a nominal grain size of about 300μm. The strain rate sensitivity index “m” was determined to be low. Based on the value of “m” and other analysis of the variation of flow stress and fracture studies, an optimum strain rate was defined. |
