Question 51

Spheroidization and graphitization are competing mechanisms that occur at overlapping temperature ranges. Spheroidization tends to occur preferentially above _______ while graphitization predominates below this temperature.

    Correct Answer: B

    Spheroidization and graphitization are processes that occur within certain temperature ranges. Spheroidization tends to occur above 1025º F, while graphitization predominates below this temperature. This distinct temperature specification helps differentiate the preferred occurrence of each process.

Discussion
ahmadmmOption: B

Spheroidization (3.59) and graphitization are competing mechanisms that occur at overlapping temperature ranges. Spheroidization tends to occur preferentially above 1025 °F (550 °C), while graphitization predominates below this temperature.
