STATISTICAL EVALUATION OF RENE 41 TENSILE PROPERTIES
Technical Report
·
OSTI ID:4828241
Results of routine acceptance tests at room temperature and at l400 deg F showed that the variation in tensile strength, yield strength, and ductility among heat-treated Rene 4l sheet specimens from a given sheet often exceeded that resulting from the combined effects attributable to producer, thickness, and heat. The distribution of strength properties was not normal in the tails; in particular, the frequency of values was higher than normal in the lowstrength tail, from which design values are usually selected. This fact must be taken into account in selecting design values based on probability of failure. (auth)
