Summary

DURING LOAD-CONTROL TENSILETESTS AT LIQUID HELIUM TEMPERATURE, THESE STEELS UNDERGO ABRUPT AND EXTENSIVE INTERMITTENT DEFORMATION, A PHENOMENON WHICH DOES NOT OCCUR WITH DISPLACEMENT-CONTROL TESTS. INVESTIGATIONS HAVE BEEN MADE INTO THE EFFECTS OF THE LOADING RATEON THE TENSILE PROPERTIES OF THESE MATERIALS AT 4 K AND IT WAS FOUND THAT 40% DEFORMATION OCCURRED IN THE AISI 310 STEEL AND THE ULTIMATE TENSILE STRENGTH DECREASED WITH AN INCREASE IN THE LOADING RATE.
