Synergistic regulation of temperature and primary knock-on atom energy on irradiation damage evolution in tantalum: a molecular dynamics study

Tantalum is a candidate material for advanced nuclear systems, but its irradiation damage mechanisms remain unclear. Using molecular dynamics with the UNEP-v1-Ziegler Biersack Littmark machine-learning potential, we simulated body-centered cubic Ta under 1–50 keV PKA irradiation at 300–900 K. Results show that threshol...
