Choose an option
-
APowder metallurgy (sintering of pressed carbide-cobalt powders)
-
BSand casting followed by machining
-
CHot forging and normalizing
-
DExtrusion and cold drawing
Answer
Correct Answer: Powder metallurgy (sintering of pressed carbide-cobalt powders)
Explanation
ConceptCemented carbides (e.g., WC–Co) are made by powder metallurgy: powder blending, pressing/compacting, and sintering to achieve high hardness and strength.
Why the others are wrongCasting and forging are not suitable for achieving the required microstructure and binder distribution of sintered carbides; extrusion/drawing is for ductile metals/polymers.
