Two martensitic steels (Fe-8.5 Cr-0.9 MoVNb and Fe-9.0 Cr-1.8 MoVNb), one ferritic steel (Fe-17 Cr-1.5 MoVNb), 316 stainless steel and Ni3Fe were irradiated with 2 MeV electrons to . The damage recovery was studied by positron annihilation and differential scanning calorimetry (DSC). Results suggest that vacancies migrate and disappear below 330 K in the martensitic phase. Vacancies in the ferritic and austenitic phases disappear around 420 K, enhancing the precipitation. Ordered Ni3Fe has three DSC annealing stages between 400 and 600 K.

Modulation of structure, morphology and wettability of polytetrafluoroethylene surface by low energy ion beam irradiation ATTA, ali; FAWZY, yasser; Bek, Alpan; Abdel-Hamid, Hassan M.; El-Oker, Mohamed M. (Elsevier BV, 2013-04-01) Polytetrafluoroethylene (PTFE) films were irradiated under vacuum with 3 keV Argon ions (Ar+) and fluences ranging from 0.5 x 10(18) to 2 x 10(18) ions/cm(2). Ion induced PTFE surface modifications of structural, morphological and wettability nature were studied by means of Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, atomic force microscopy and force spectroscopy, and contact angle measurements. FTIR analysis indicated defluorination of PTFE due to the rupture of C-C and C-...
Nanohardness measurements of heavy ion irradiated coarse- and nanocrystalline-grained tungsten at room and high temperature El-Atwani, O.; Weaver, J. S.; Esquivel, E.; Efe, Mert; Chancey, M. R.; Wang, Y. Q.; Maloy, S. A.; Mara, N. (Elsevier BV, 2018-10-01) Heavy ion irradiation was performed on coarse and nanocrystalline-grained tungsten (CGW and NGW, respectively) at room temperature (RT) and 1050 K from 0.25 to 4 dpa to simulate radiation damage for fusion energy applications. TEM and nanohardness measurements of irradiated samples were made to quantify the radiation tolerance of these two candidate materials. In this case, TEM is used to quantify the defect morphology at low dpa values and determine the barrier strength coefficients of the different defect...
Measurement of the t(t)over-bar production cross section in pp collisions at root s=8 TeV in dilepton final states containing one tau lepton Khachatryan, V.; et. al. (Elsevier BV, 2014-12-01) The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying tau lepton from the process t (t) over bar -> (l nu(l))(tau nu(tau))b (b) over bar, where l = e, mu. The data sample corresponds to an integrated luminosity of 19.6 fb(-1) collected with the CMS detector in proton-proton collisions at root s = 8 TeV. The measured cross section sigma(t (t) over bar) = 257 +/- 3 (stat) +/- 24 (syst) +/- 7 (lumi) pb, assuming a top-quark mass of 172.5...
Spectroscopy of the ODD-ODD nucleus 76As and its supersymmetric description Hoyler, F.; Jolie, J.; Colvin, G.G.; Börner, H.G.; Schreckenbach, K.; Van Isacker, P.; Fettweis, P.; Göktürk, H.; Dehaes, J.C.; Casten, R.F.; Warner, D.D.; Bruce, A.M. (Elsevier BV, 1990) Gamma rays and conversion electrons following thermal-neutron capture in 75As have been measured using the Ge pair spectrometer PN4, the bent crystal spectrometers GAMS and the β-spectrometer BILL at the ILL. Coincident γ-rays were recorded at the CEN/SCK Mol, and average resonance capture at En = 2 and 24 keV has been studied at the HFBR of BNL. The neutron binding energy in 76As was determined to be 7328.498 ± 0.075 keV. The resulting level scheme for 76As greatly improves the knowledge on this odd-odd nu...
Damage relief of ion-irradiated Inconel alloy 718 via annealing Fincher, Cole D.; Turman, Haley; French, Aaron; Chancey, Matthew; Gigax, Jonathan; Aydoğan Güngör, Eda; Zhao, Dexin; Yadav, Digvijay; Xie, Kelvin; Wang, Yongqiang; Borden, Mike; Shao, Lin; Maloy, S. A.; Pharr, Matt (Elsevier BV, 2020-09-01) Inconel alloy 718 is a high-strength and corrosion resistant alloy that is commonly used as a beamline vacuum window. The accumulation of irradiation-induced damage substantially decreases the window's service lifetime, and replacing it engenders significant beamline downtime. With this application in mind, herein we examine whether post-irradiation annealing can alleviate irradiation-induced damage of Inconel alloy 718. Inconel alloy 718 was received in a solution annealed state. We then irradiated samples...
