While this concept of mechanical instability offers a potential explanation for the large discrepancies between FP and TC lattice stabilities for some elements, the calculations of Craeivich et al. (1994) showed that such instabilities also occur in many other transition elements where, in fact, FP and TC values show relatively little disagreement. The key issue is therefore a need to distinguish between permissible and non-permissible mechanical instability. Using the value of the elastic constant C as a measure of mechanical instability, Craievich and Sanchez (1995) have found that the difference between the calculated elastic constant C for f.c.c. and b.c.c. structures of the transition elements is directly proportional to the FP value of(Fig. 6.9(a)).

In the USA, LOX have been used primarily in the strip mining of coal. For example, in 1950, 99.5% of all the LOX used was in coal mining (Ref 18). Most of this must have been for moving overburden, since LOX are non-permissible (not allowed by law in gassy mines),...
