1. A method for growing a single-crystal metal, the method comprising:

  • heating a polycrystalline metal specimen in a non-oxidizing environment;

    applying a first plastic strain to the heated polycrystalline metal specimen to initiate growth of a grain of the heated polycrystalline metal specimen by displacing distal ends of the heated polycrystalline metal specimen; and

    applying a second plastic strain to the heated polycrystalline metal specimen to propagate growth of the grain to form a single-crystal metal by displacing a first distal end of the heated polycrystalline metal specimen at a faster rate than a second distal end of the heated polycrystalline metal specimen.
