摘要
The influence of strain-rate on the room temperature mechanical properties of Dual-Phase and Transformation Induced Plasticity (TRIP) steels was investigated. The results showed that both plastic strain, and strength properties increased with increasing strain rates at high strain rates. At strain rates lower than approximateil 1 s(-1) the properties no longer have an advantageous proportionality to strain rate and remain strain rate neutral. Possible explanations are offered for trends exhibited, in terms of thermal and athermal considerations, in relation to the respective microstructures of the two steels.
