WebCorrect answers: 3 question: A) using the result of problem 4.8(a), compute the radius of an octahedral interstitial site in fcc iron. (b) on the basis of this result and the answer to problem 4.9, explain why a higher concentration of carbon will dissolve in fcc iron than in iron that has a bcc crystal structure. WebTherefore, the hardening by interstitial atoms is more effective in bcc alloys than in fcc materials, where the lattice distortion is isotropic. At larger solute concentrations, the …
