Which consequence results when casting a steel turbine blade in a vacuum?

💡 Explanation

Increased ductile fracture resistance occurs due to vacuum degassing removing dissolved gases, which limits pore formation via heterogeneous nucleation during solidification rather than causing embrittlement; therefore, toughness increases rather than strength reduction.
