What type of material structure is least ductile? A) BCC B) Ferrite C) FCC D) CPH
Understand the Problem
The question is asking about different types of material structures and which one exhibits the least ductility among them. Ductility refers to the ability of a material to deform under tensile stress.
Answer
CPH (HCP - Hexagonal Close Packed)
The final answer is CPH (also known as HCP - Hexagonal Close Packed)
Answer for screen readers
The final answer is CPH (also known as HCP - Hexagonal Close Packed)
More Information
The Hexagonal Close Packed (HCP) structure is typically less ductile compared to Body Centered Cubic (BCC) and Face Centered Cubic (FCC) structures because it has fewer slip systems. This makes it more difficult for atoms to move past each other under stress.
Tips
A common mistake is confusing FCC with CPH due to their similar nomenclature. FCC is generally more ductile than BCC and CPH.
