Reactor Pressure Vessel Steels ASTM A533B and A508 C1.2: Crack Opening Displacement (COD) Test Results

摘要

This report describes the crack opening displacement (COD) test results for the steels ASTM A533B and A508 C1.2 obtained in connection with a program initiated to gather and create information concerning the manufacturing variables, e.g. heat treatment, needed in the assessment of the structural integrity of reactor pressure vessels. The elastic-plastic fracture toughness was studied after applying various austenitizing and tempering temperatures.
