The Correct Option is A
Solution and Explanation
Step 1: Concept Powder metallurgy is a fabrication technique that involves preparing metal powders and then consolidating them into a solid shape.
Step 2: Meaning The process must follow a logical order: powder creation, mixing, forming, and heating.
Step 3: Analysis Atomisation (P) is the method to produce the powder. Blending (S) mixes the powders and lubricants. Compaction (R) presses the powder into a "green" shape. Sintering (Q) heats the part to bond particles.
Step 4: Conclusion The correct logical and industrial sequence is P $\rightarrow$ S $\rightarrow$ R $\rightarrow$ Q. Final Answer: (A)
