  • Development of hard and wear-resistant density modulated coatings by magnetron sputtering 
    Bolat, R.; Utegulov, Z.N.; Yakupov, T.; Taha, D.; Karabacak, T. (Nazarbayev University, 2013)
    The major task of our project is to develop a density modulated tungsten-based films to achieve high adherence of the entire hard sandwiched film structure to the substrate.
  • GHZ phononic band-gapcrystals: fabrication, characterization and modeling 
    Rakhymzhanov, A.; Utegulov, Z.N.; Guney, D.; Veres, I.A. (Nazarbayev University, 2013)
    Phononic band-gap crystals (PBGCs) are acoustic analogues of photonic band-gap crystals. PBGC is a composite structure possessing periodic variations of sound velocities and mass densities with high acoustic impedance ...
  • Laser thermoelastic generation in metals above melt threshold 
    Every, A.G.; Utegulov, Z.N.; Veres, I.A. (Nazarbayev University, 2013)
    We have established the detailed spatio-temporal evolution of heat conduction of the irradiated sample due to the incidence of a laser pulse, including the temperature rise of the solid phase preceding the melting, and the ...
  • Localized detection of phase transition in tungsten by laser ultrasonics 
    Utegulov, Z.N.; Reese, S.J.; Farzbod, F.; Schley, R.S.; Hurley, D.H. (Nazarbayev University, 2013)
    We demonstrated a method for localized, furnace-free detection of the onsets of melting and ablation in polycrystalline tungsten using nanosecond laser ultrasonics. Pulsed laserinduced melting is characterized by a delay ...
  • Thermo-acoustics of pulsed laser-induced phase transition in tungsten by FDTD numerical calculation 
    Veres, I.A.; Utegulov, Z.N.; Every, A. (Nazarbayev University, 2013)
    In the presented work metal-to-liquid phase transition induced by a pulsed-laser was investigated. A numerical FDTD technique based on the solution of the coupled heat and wave equations was applied. It was demonstrated ...
  • Transformations and cracks in zirconia films leading to oxidation of zircaloy 
    Kadiri, H.El; Utegulov, Z.N.; Khafizov, M.; Asle Zaeem, M.; Mamivand, M.; Oppedal, A.L.; Enakoutsa, K.; Cherkaoui, M.; Graham, R.H.; Arockiasamy, A. (Nazarbayev University, 2013)
    This work was aimed to identify the root cause of breakaway oxidation of Zircaloy and the origin of Zircaloy cladding failure. Circumferential compressive stress is highly promoted by tetragonal to monoclinic phase transition. ...
