“…Structural modifications such as amorphization and order-disorder transitions in metallic systems can be driven by either irradiation or mechanical alloying [35,36], and are sufficiently similar that they can be mathematically described in identical fashion [37,38]. In semicrystalline polymeric materials, irradiation generally induces defects into, and progressively collapses, the crystalline lattice, which is accompanied by a reduction in the melting point [21,23].…”
