Abstract

We present a first He ion channeling study on thermal stability (under isochronal vacuum furnace annealing at 300-650°C) of metastable solid solution phases produced by pulsed ruby laser treatment of Al implanted with Cr and Mo. Laser treated Cr exhibits strong redistribution inferred to be due to intermetallic phase precipitation which appears to be enhanced by quenched-in defects. In contrast, laser treated Mo shows no redistribution but only a loss of substitutionality. Instead of annealing, thermal treatment produces an increase in host dechanneling yield for all laser treated samples. Detailed comparison with thermal recovery of as implanted phases demonstrates the key role played by quenched-in defects.
