Chemistry · Solid State and Alloys
Given below are two statements regarding alloys: Statement I: To form interstitial alloys, the radius ratio of the smaller atom to the larger atom should ideally be in the range of 0.414 - 0.732 to fit into octahedral holes. Statement II: Two different metals having metallic radii differing by less than 15% (e.g., around 10%) and similar crystal structures can form a good substitutional alloy. In the light of the above statements, choose the most appropriate answer:
- 1Statement I is incorrect but Statement II is correct
- 2Statement I is correct but Statement II is incorrect
- 3Both Statement I and Statement II are incorrect
