Chapter 11 homework solutions Problem 1 – answer page 384. The matrix should be soft and ductile. The hard dispersed phase should be discontinuous. The dispersed phase should be small and numerous. The dispersed phase particles should be round. Higher concentrations of dispersed phase strengthen alloy. Problem 6 - answer page 390. When three phases are in equilibrium during the reaction, there are no degrees of freedom. These reactions occur at a fixed temperature and composition, and it is also understood to be at a fixed pressure.

Unformatted text preview: Using the Gibbs phase rule, 1 + C = F + P where C = components, F = degrees of freedom and P = phases, One calculates F = 1 + C P = 1 + 2 3 = 0 at the invariant point. These reactions are known as invariant.
