Available in PDF, EPUB and Kindle. Book excerpt: This task examines the fracture toughness curve shifts and changes in shape for irradiated welds with low CVN upper-shelf energy (USE). The information developed under this task will augment information obtained from other HSSI tasks performed on two high-USE weldments under the Fifth and Sixth Irradiation Series and on a commercial, low USE under the Tenth Irradiation Series. The results will provide an expanded basis for accounting for irradiation-induced embrittlement in RPV materials. Three low-USE welds have been ordered from ABB-Combustion Engineering (ABB-CE), Chattanooga, Tennessee, and two of them have been delivered to ORNL. ABB-CE fabricated the welds for the Fifth and Sixth Series. Preliminary results of mechanical and chemical tests from these two welds are presented below. The Linde 80 flux was used for all three welds. One weld, Weld 1, was made with the 73W weld wire. Weld wire 73W had copper added to the melt to reduce the variations that are associated with copper-coated weld wire. The other two welds were fabricated with a commercially available copper-coated weld wire, L-TEC 44 heat 44112. One of these two welds, Weld 2, has a target copper level of 0.31 %. This copper level could not be attained using the copper-coated wire, and the coating will be stripped from the wire, which contains 0.07 % Cu. To attain the target copper level, supplemental copper will be added to the weld puddle using an ABB-CE proprietary process. This will slightly delay the delivery of weld 2, the expected delivery date is now the end of April 1995. Weld 3 was fabricated with the same heat of the L-TEC 44 copper-coated weld wire as weld 2, but with supplemental copper added to the weld puddle, which resulted in a weldment containing an average of 0.424 % Cu. The semiannual report for October 1993 through March 1994 discusses the reasons for the above choices of copper content and welding wire.

This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the Heavy-Section Steel Irradiation (HSSI) Program Tenth Irradiation Series was to develop a fracture mechanics evaluation of weld metal WF-70, which was taken from the beltline and nozzle course girth weld joints of the Midland Reactor vessel. This material became available when Consumers Power Company of Midland, Michigan, decided to abort plans to operate their nuclear power plant. WF-70 is classified as a low upper-shelf steel primarily due to the Linde 80 flux that was used in the submerged-arc welding process. The master curve concept is introduced to model the transition range fracture toughness when the toughness is quantified in terms of K{sub Jc} values. K{sub Jc} is an elastic-plastic stress intensity factor calculated by conversion from J{sub c}; i.e., J-integral at onset of cleavage instability.

Available in PDF, EPUB and Kindle. Book excerpt: From Charpy to Present Impact Testing contains 52 peer-reviewed papers selected from those presented at the Charpy Centenary Conference held in Poitiers, France, 2-5 October 2001. The name of Charpy remains associated with impact testing on notched specimens. At a time when many steam engines exploded, engineers were preoccupied with studying the resistance of steels to impact loading. The Charpy test has provided invaluable indications on the impact properties of materials. It revealed the brittle ductile transition of ferritic steels. The Charpy test is able to provide more quantitative results by instrumenting the striker, which allows the evolution of the applied load during the impact to be determined. The Charpy test is of great importance to evaluate the embrittlement of steels by irradiation in nuclear reactors. Progress in computer programming has allowed for a computer model of the test to be developed; a difficult task in view of its dynamic, three dimensional, adiabatic nature. Together with precise observations of the processes of fracture, this opens the possibility of transferring quantitatively the results of Charpy tests to real components. This test has also been extended to materials other than steels, and is also frequently used to test polymeric materials. Thus the Charpy test is a tool of great importance and is still at the root of a number of investigations; this is the reason why it was felt that the centenary of the Charpy test had to be celebrated. The Société Française de Métallurgie et de Matériaux decided to organise an international conference which was put under the auspices of the European Society for the Integrity of Structures (ESIS). This Charpy Centenary Conference (CCC 2001) was held in Poitiers, at Futuroscope in October 2001. More than 150 participants from 17 countries took part in the discussions and about one hundred presentations were given. An exhibition of equipment showed, not only present day testing machines, but also one of the first Charpy pendulums, brought all the way from Imperial College in London. From Charpy to Present Impact Testing puts together a number of significant contributions. They are classified into 6 headings: •Keynote lectures, •Micromechanisms, •Polymers, •Testing procedures, •Applications, •Modelling.

Available in PDF, EPUB and Kindle. Book excerpt: The Report provides comprehensive toughness criteria for welded ship hulls that can be used for steels of all strength levels. Because of the fact that stress concentrations are always present in large complex welded structures and therefore high stresses as well as discontinuities or flaws will be present in welded ship hulls, primary emphasis in the proposed fracture-control guidelines is placed on the use of steels with moderate levels of notch-toughness and on the use of properly designed crack arresters. In general, concepts of fracture mechanics are used to develop the material toughness level that is required for fail-safe operation of welded ship hulls.
