Overview

Observational analysis found blisters and a cell size of 200 nm in tungsten after helium plasma exposure, suggesting thermal effects influence solidification.

Key Points

  • Surface melting and microcracks observed in tungsten due to helium plasma exposure.
  • X-ray diffraction analysis shows reduced structural defects after treatment.
  • Solidification results in unique crystallization texture directed by temperature gradient.
  • Investigating thermal stress implications reveals decreased microhardness in exposed layers.
