Henry Submitted to the Department of Ocean Engineering in May, 1974, in partial fulfillment of the requirements for the degree of Master of Science in Ocean Engineering and Masters of Science in Mechanical Engineering. ABSTRACT Out-of-plane distortion caused by angular changes at fillet welds in aluminum structural panels was examined from two viewpoints. In the first phase of this work a series of experiments was conducted to examine elastic-plastic prestraining of test specimens to be fillet welded as a means of reducing out-of -plane distortion. Data gathered from these tests was correlated with previous experiments in the use of aluminum. A guide in the use of elastic-plastic prestrain- ing for 3/8" and 1/2" was developed. In phase two of this work a two-dimensional program was adapted to the structural aluminum panels used in phase one and tested for accuracy. -

924 Iaea-Sm-310/ 69P
924 IAEA-SM-310/ 69P RESULTS FROM POST-MORTEM TESTS WITH MATERIAL FROM THE OLD CORE-BOX OF THE HIGH FLUX REACTOR (HFR) AT PETTEN M.I. de Vries Netherlands Energy Research Foundation, ECN, Eetten, The Netherlands M.R.. Cundy Joint Research Centre, Patten, The Netherlands 925 RESULTS FROM POST-MORTEM TESTS WITH MATERIAL FROM THE OLD CORE-BOX OF THE HIGH FLUX REACTOR (HFR) AT PETTEN ABSTRACT Results are reported from hardness measurements, tensile tests and fracture mechanics experiments (fatigue crack growth and fracture toughness) on 5154 aluminium specimens, fabricated from remnants of the old HFR core box. The specimen material was exposed to a maximum thermal neutron fluence of 7.5 * 1026n/m2(E < 0.4eV). Test results for this fluence (ratio of the thermal to fast neutron flux density is 1.17) are: hardness 63HR15N, 0.2 - yield strength 525 MPa and total elongation 2.2% strain. Material which was exposed to a lower thermal fluence of 5.6 * 10 n/m , but with a thermal to fast neutron ratio of about 4, shows more radiation hardening : 67HR15N, 0.2 - yield strength 580 MPa and 1.5% total elongation. -5 -3 Fatigue crack growth rates range from 5 * 10 mm/cycle to 10 mm/cycle for AK ranging from 8 to 20 MPa)|m. The most highly exposed (7.5 * 10 n/m ) material shows accelerated fatigue crack growth due to unstable crack extension at AK of about 15 Mpa^m. The lowermost meaningful measure of plane strain fracture toughness is 18 MPa^m. Except for the fracture toughness which is a factor of about 3 higher the results show reasonable agreement with the expected mechanical properties estimated in the "safe end-of-life" assessment of the old HFR vessel. -

Abstract Sheets of TD-NiCr processed using techniques developed to produce uniform material were tested to supply mechanical and physical property data. Two heats each of 0. 025 and 0. 051 cm thick sheet were tested. Mechanical properties evaluated included tensile, modulus of elasticity, Poisson's Ratio, compression, creep-rupture, creep strength, bearing strength, shear strength, sharp notch and fatigue strength. Test temperatures covered the range from ambient to 1589K. Physical properties were also studied as a function of temperature. -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. The joints of aluminium and aluminium alloys with the different types of steel were studied. The structural effects occurring during the welding process were described. The mechanical properties using, for example, (i) microhardness measurements, (ii) tensile tests, (iii) bending tests, and (iv) shearing tests were determined. In order to obtain high-quality joints the influence of different configurations of the process such as (i) changing the geometry of bonding surface, (ii) using the interlayer, or (iii) heat treatment was analyzed. Finally, the issues related to the selection of optimal parameters of friction welding process were also investigated. 1. Introduction often very difficult.
