Description |
Grain growth, cavitation and flow stress data, which are available together for limited materials during superplastic deformation, were collected and analyzed to explore the interdependence in microstructural changes and its impact on flow properties. The grain size (d(g)) varies with strain (is an element of) as d(g) proportional to epsilon(c), c being strain exponent, whereas cavity volume (C-v) follows C-v = A epsilon(2) + B epsilon + type polynomial relationship, where A, B and C are coefficients. The interrelationship between C-v and d(g) can be expressed by: C-v proportional to exp(d(g)). While flow hardening is attributed to grain growth in the early part of deformation, the occurrence of cavitation is found to cause flow softening at later stage of deformation.
