Abstract

Abstract

En 中文
• Ratios of CSL boundaries and Σ9 + Σ27 boundaries both increases with annealing time. • Melting temperature reduces in order of CSL boundary, random boundary, and NbC. • Liquation crack primarily occurs at random boundaries and hardly at CSL boundaries. • Effective distribution of CSL boundary reduces liquation cracking susceptibility.
