摘要: Abstract The influence of specimen orientation, stress intensity factor ( K I ), and iodine concentration on the iodine-induced corrosion cracking growth rates in Zircaloy-4 was investigated iodized methanol solutions at ambient temperature. When is lower than 20 MPa.m 1/2 , intergranular mixed intergranular/transgranular crack propagation increase linearly with − I,th being onset factor. content induces an rate for a given decrease . orientation second order parameter. A law, depending content, proposed.
