energies. For this reason, the Mo-L rather than the Mo-K

was used for the quantification, and the W-L or Ta-L

lines were not used at all. An example of a comparison

between results calculated from both the Mo-Kotand the

Mo-I line is given below.

 The sample is the ternary alloy #17. As in the

previous example, a large probe size was used.

Note: The ratio L~/LO'= .2265 was used to reduce the

measured intensity of the Mo-La4+ Mo-L- peak. The L?/L*

ratio was calculated from the MAGIC program.

 The EDS results in Table 5.3 do not include values for

either the W or Ta quaternary additions. The analyses will
