Title:
The Strength and Ductility of Steel Castings at Hot Tearing Temperatures - 1250-1400 Degrees Centigrade
Report Date:
1938-09-22
Abstract:
Equipment has been devised and constructed to test cast steel at temperatures (1250 deg C. to 1400 deg C.) near the solidification temperature of steel. This equipment consists of a small type tensile machine operating against a calibrated spring attached to the mold. A test bar has been developed which shows a uniform temperature throughout its gage length. Preliminary testing has established the nature of existent variations in results and the shape and trend of tensile strength and ductility (elongation) curves.
