nvlpubs.nist.govgreatly affected by residual stresses within the samples. This was demonstrated by comparing the expansion and/or length of each sample in the annealed condition with their corresponding proper ties in a strained condition. After sample D had been annealed it was machined from a 0.75-inch diameter to a 0.5S-inch-diameter rod.
