A program was planned to obtain quantitative information on the effects of residual impurity elements on the reversible temper embrittlement susceptibility of Ni-Cr-Mo-V rotor steels. The statistical design of the experiment and statistical analysis of the data are described. The basic design was a supplemented ½ fraction of a 2 factorial to study the effects of P, Mo, Sn, As, and Sb, including 2-factor interactions among these elements.
