This is the third progress report on The Fracture Mechanics and Mechanical Testing Laboratory activities in the framework of the co-operation programme between the Dept. of Metallurgy, Nuclear Research Centre, AEA, Egypt and Forschungszentrum Jülich, Germany. This report covers the R&D activities in the period 1995-1998. The report is concerned with the following main activities in which the facilities of the laboratory were utilized: $\textbf{A. Update ofthe Co-operation Programme in Materials Testing}$ $\textbf{A.1 Supply of the equipment by Forschungszentrum Jüllich}$ $\textbf{A.2. Upgrading of the PSB250 Testing Machine (funded through AEA budget)}$ $\textbf{B. Work on Pressure Vessel Steels}$ This deals with the review on the effect of chemical composition of pressure vessel steels on their sensitivity to irradiation embrittlement. This work originated from previous joint work on neutron irradiation of various types of pressure vessel steels. $\textbf{C. Work on Low Alloy Steel}$ This includes studying the effect of various austenitization treatments on microstructure and mechanical properties (tensile and impact) of the high strength low alloy 34CrNiM06 steel. $\textbf{D. Work on Weldments of Stainless and Carbon Steels D.1}$ Effect of electrochemical hydrogen charging on the mechanical properties and corrosion behaviour of both solution treated and sensitized 304L stainless steel base metal and 308L stainless steel weldment. Mechanical properties are determined through tensile, constant load and impact tests. Corrosion behaviour was evaluated using different techniques. $\textbf{D.2}$ Effect of thermal ageing on impact toughness of 304 stainless steel weldment. This involved the effect of thermal ageing time at 700 °C on the impact toughness of 304 stainless steel weld joint. A correlation was made between the change in toughness and microstructure. $\textbf{D.3.}$ Assessment Of Using Austenitic Stainless Steel Weld Metal For Repairing CMn Steel Components $\textbf{E. Future Work Programme}$ |
