Page 59 - Elastic limit (pounds per square inch). Yield point (pounds per square inch). strength (pounds per square inch). Tensile Elongation (per cent).
Page 59 - Furthermore, no ductility was displayed by either after rupture, which shows conclusively that the properties exhibited by the longitudinal static tensile specimen were not utilized previous to failure. (9) The ordinary tensile tests showed a complete lack of ductility at right angles to the axis of the screw.

Page 59 - Our present knowledge would, therefore, lead us to conclude that brittleness would be experienced at right angles to the principal axis. The unnotched Charpy tensile specimens, taken at right angles to the axis of the screw, verify this conclusion.
Page 58 - The original martensitic formation caused by quenching still persists, which is in itself an indication of brittieness, and the presence of such a structure would have been sufficient grounds for recommending retreatment.
