Titanium (Ti) crystallizes in fcc lattice. It reacts with C or H intersititally and these elements occupy the voids of host lattice (i.e., Ti) radius that can be occupies in TVs without Casing strain in the host lattice.
What is the maximum ratio of "foreign" atom radius (i.e., H atom) to host atom (i.e ., Ti) radius that can be occupies in TVs without causing a strain in the host lattice.
A. 0.225
B. 0.414
C. 0. 732
D. 0.9
