Radiation-induced Segregation and Void Swelling in 304 Stainless Steel
. Void swelling and radiation-induced segregation have been measured in 304 stainless steel. Samples were irradiated in the outer regions of the EBR-11reactor where displacement rates of 2.OX10-8and 6.6 xl 0-8dpds are comparable to those in pressurized water reactor components. Samples were inadiated at temperatures from 371-390°C to total doses of up to 20 dpa. Void swelling reached a maximum ...
متن کاملRadiation Effects in Metals: Void Swelling and Irradiation Creep
Until about 1967 the most detrimental radiation effect expected to be suffered by the stainless-steel cladding of the fuel elements of the projected liquid-metal-cooled fast breeder reactor (LMFBR) was embrittlement due to exces sive hardening at low temperatures or helium agglornrration at grain boundaries at high temperatures, These problems, however, were at least qualitatively understood, ...
متن کاملResponse to “Shear Impossibility—Comments on ‘Void Growth by Dislocation Emission’ and ‘Void Growth in Metals’”
We thank the authors of Ref. [1] for their comments and interest in our work [2–6]. We agree that the emission of shear loops on one single shear plane cannot lead to void growth. However, our simulations suggest that coordinated shear on non-parallel planes can lead to void growth/shrinkage [3–5]. Detailed descriptions of this process are still being worked out and represent an exciting area f...
متن کاملShear impossibility: Comments on “Void growth by dislocation emission” and “Void growth in metals: Atomistic calculations”
Recently it was proposed that voids in crystals could grow by emission of shear dislocation loops [V.A. Lubarda, M.S. Scheider, D.H. Kalantar, B.A. Remington, M.A. Meyers, Acta Materialia 52 (2004) 1397–1408]. Even more recently, this proposal was ostensibly supported by molecular simulations of voids in strained single crystals [S. Traiviratana, E.M. Bringa, D.J. Benson, M.A. Meyers, Acta Mate...
متن کاملVoid growth by dislocation emission
Laser shock experiments conducted at an energy density of 61 MJ/m revealed void initiation and growth at stress application times of approximately 10 ns. It is shown that void growth cannot be accomplished by vacancy diffusion under these conditions, even taking into account shock heating. An alternative, dislocation-emission-based mechanism, is proposed for void growth. The shear stresses are ...
