DTrue only at cryogenic temperatures
Answer
Correct Answer: Correct (True)
Explanation
ConceptIn plain carbon steels, a matrix of ferrite (very soft, ductile) with pearlite (lamellar ferrite + cementite) yields an overall soft and ductile behavior (typical of low-carbon and mild steels). Increasing pearlite content raises strength but maintains useful ductility.
Final AnswerCorrect (True)
