The peak - to - background ratio is usually poor in residual stress measurements ,
especially with hardened steels . When employing the centroid or half - value
breadth , background is subtracted , and this introduces an additional error .

The latter ratio determines the value of a and therefore the path length within the
sample . A range of 812 values are given in Table I for pure chemical elements
with low , intermediate , and high atomic numbers . They extend from a low of 0 .
