A series of YBa~Cu30 7 8(YBCO) epitaxial films and crystals were irradiated with energetic heavy ions (Sn 30+ or Ag29+ at energy 0.58 GeV) to produce columnar defects of highly disordered material. The irreversibility lines, B\*(T}, show enhancement due to the increased pinning. However, while B\*
## Measurements of the electrical resistivity, p, and of the critical current, /,, of polycrystalline Y,Ba,Cu,O,\_, samples before and after being melted superficially are presented. The melting was done by heating the samples at 1050°C during a few minutes, and then annealing at 900°C in flowing
