The pressure dependence of the superconducting transition temperature's, Tc, of fourteen samples in the pseudoternary system (Th1-xYx)Rh4B4 are reported for hydrostatic pressures up to 21 kbar. The Y rich samples show an enhancement of Tc with applied pressure, whereas for the Th rich compounds Tc is depressed by pressure. A broad plateau in dTc/dp as a function of x is observed for nearly equiatomic (0.4 <= x <= 0.80) compositions. The non-linear behavior of Tc as a function of pressure for the Y rich samples (x > 0.80) is discussed with reference to prior measurements on YRh4B4. Observation of this non-linearity may be related to the purity of the Y source material or the presence of a pressure-induced phase transformation. (12 References).
