Answer:
Hello the options attached to this question is missing below are the options
a) Martensite
b) Pearlite
c) Bainite
d) Tempered martensite
answer : Tempered martensite ( d )
Step-by-step explanation:
The Highest strength carbon steels with some ductility have a microstructure that is described as Tempered martensite
The microstructure that is formed when a martensite ( rapidly cooled ) is heated up to the temperatures of 500°C is the highest strength carbon steels with some ductility
