- 3 Iron Fe Undergoes An Allotropic Transformation At 912 C Upon Heating From A Bcc X Phase To An Fcc Y Phase Acco 1 (15.79 KiB) Viewed 19 times
3. Iron (Fe) undergoes an allotropic transformation at 912°C: upon heating from a BCC(x phase) to an FCC (y phase). Accompanying this transformation is a change in the atomic radius of Fe- from Racc = 0.12584 nm to Recc= 0.12891 nm - and, in addition, a change in density (and volume). Compute the percentage volume change associated with this reaction. Does the volume increase or decrease? 4. Sketch a monoclinic unit cell, and within that cell, a [101] direction. 5. a Draw an orthorhombic unit cell, and within that cell, a (021) plane. b Draw a monoclinic unit cell, and within that cell, a (200) plane.
