Abstract

PURPOSE:To measure a Fuller's brittle point, by cooling a steel plate applied a sample and detecting a destruction sound produced by a crack in the sample. CONSTITUTION:A destruction sound is produced at the time of cracking a sample by cooling a steel plate 11 applied the sample and reaching a Fuller's brittle point. The Fuller's brittle point is measured by catching said sound and measuring the temperature at that time by a thermometer and then, detecting the temperature destructing the sample. The destruction sound produced in a closely enclosed test tube 8 is lead out of a sound conducting tube 5 by making a hole in a rubber plug 6 of the tube 8 of a tester and attaching the tube 5 and the destruction sound is detected by ear with an acoustic instrument 4 attached at the tip end of the tube 5. Cooling is carried out by adding finely crushed dry ice to a cooling medium 9 through a funnel 3.
