Which outcome occurs when rapid hydrocarbon vaporization cools reactor surfaces?

💡 Explanation

Steel experiences ductile-brittle transition; rapid cooling causes decreased toughness, therefore embrittlement promotes crack propagation rather than plastic deformation, because stress concentrates at flaws when temperature suddenly drops below its ductile-brittle transition during cooling.
