Using a relativistic hadron transport model, we investigate the utility of the elliptic flow excitation function as a probe for the stiffness of nuclear matter and for the onset of a possible quark-gluon-plasma phase transition at alternating-gradient synchrotron energies 1{approx_lt}E{sub beam}{approx_lt}11A GeV . The excitation function shows a strong dependence on the nuclear equation of state, and exhibits characteristic signatures which could signal the onset of the transition. {copyright} {ital 1998} {ital The American Physical Society }
