Abstract

In order to evaluate the cryogenic fracture toughness and the adiabatic heating of thick section weldment in forged JN1 type austenitic stainless steel plate with nickel base filler metals for fusion reactor magnets of the next generation, elastic-plastic fracture toughness (J_IC) testing was performed with IT compact tension specimens at liquid helium temperature (4 K). Testing was conducted in accordance with ASTM standard E813-89 for determining J_IC using the unloading compliance technique to monitor crack growth. Au/0.07%Fe-Chromel thermocouples were used to measure the temperature rise near the crack tip. The effects of specimen location and nitrogen content on J _IC are examined.
