Serration Behavior in Pd77.5Cu6Si16.5 Alloy

Serration Behavior in Pd77.5Cu6Si16.5 Alloy

The strain-rate-dependent plasticity under uniaxial compression at the strain rates of 2 × 10−3, 2 × 10−4 and 2 × 10−5 s−1 in a Pd77.5Cu6Si16.5 alloy is investigated. At different strain rates, the serration events exhibit different amplitudes and time scales. The intersection effects take place obv...
