N2 - DC magnetic measurements on the high-Tc superconductors YBa2Cu4O8 (124, Tc=80 K) and Y0.9Ca0.1Ba2Cu4O8 (Tc=87K) are reported. The irreversible lines of 124 and ceramic YBa2Cu3O7 (123) are quite similar. The results show that there is no significant difference between the critical currents of the 124 phase and those of the 123 phase. Conversions of 124 into 123+CuO does not change the grain size of the material but enhances its critical current density.
