Question:
Solid solution strengthening of an alloy result when alloying addition forms
Solid solution strengthening of an alloy result when alloying addition forms
Show Hint
Solid Solution = Single Phase. If it forms a second phase or precipitates, the mechanism is called dispersion or precipitation hardening.
Updated On: Jul 4, 2026
- Second phase
- Precipitates
- Single phase
- Eutectic mixture
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept Strengthening mechanisms in metals often involve creating obstacles to the motion of dislocations.
Step 2: Meaning Solid solution strengthening occurs when solute atoms are added to the solvent lattice.
Step 3: Analysis The solute atoms create local lattice strains (compressive or tensile) that interfere with the movement of dislocations.
Step 4: Conclusion This mechanism specifically occurs when the alloy remains as a single, homogenous solid solution phase. Final Answer: (C)
