Higher irreversibility fields (H(irr)) increase the upper bound for applications of superconductors and could expand market penetration. We present the studies in pulsed field (up to 65 T) of superconducting films on flexible metal substrates. We investigate the effect of disorder on H(irr) at different field orientations for YBa(2)Cu(3)O(y) and BaZrO(3)-nanoparticle-dispersed Y(0.77)Gd(0.33)Ba(2)Cu(3)O(y) (YGdBCO+BZO). We find that H(irr) is higher for YGdBCO+BZO along the c-axis and at intermediate orientations. The vortex melting transition is investigated using the resistive transition's critical exponent. The behavior can be explained by the mixed pinning landscape from randomly distributed BZO nanoparticles and c-axis correlated disorder.
