Al and Ti are also present in minor amounts.
Superalloy 718 is age-hardened by combined precipitation of fine γ'' (a meta stable intermetallic compound Ni3Nb, tetragonal centered crystal) and, of with minor contribution, of γ' (intermetallic compound Ni3(Ti,Al), simple cubic crystal) phases in an austenitic matrix γ (face centered cubic).
These particles are considered irreversible traps of hydrogen with an activation energy 1 I�CO�EL is a trademark of Inco Alloys International, Inc., Huntington, WV.

Bita et al. addressed this issue by proposing the graphoepitaxy of self-assembled block copolymers (BCPs) using two-dimensional periodic-patterned templates [1].
In these technologies, Sakurai et al. [2], Black [3], and Kitano et al. [4] proposed an alternative guide-line template for self-assembly.

Elzubair et al. [12] also reported that alkali treatment improved flexural properties of piassava fiber/rHDPE composites.
Stark et al. [17] also found that flammability of wood flour/HDPE increased with increasing wood flour content.
Elzubair et al. [12] also observed that alkali treatment improved the compatibility of piassava fiber/rHDPE composites.

The bands at the wavenumbers 470 and 1000 cm-1 corresponded to the Si–O–Si vibrations, whereas the band at the wavenumber 530 cm-1 corresponded to Si–O–Al bending vibrations [8,9].
The band at 918 cm-1 is from the Al–O–Al vibrations [10,11].

Barlat et al. [2] introduced Yld2000-2d, which considers stresses and r-values based on uniaxial tension test results in three directions, equi-biaxial stress and its strain increment ratio.
Vegter et al. [3] proposed a plane stress yield function based on interpolation by second order Bézier curves.
Tsutamori el al. [4, 5] have proposed a plane stress yield function using third order Bézier curves, which connects uniaxial stress states and equi-biaxial stress states.

Role of Nonequilibrium Vacancies in Spinodal Decomposition According to the classic theory of spinodal decomposition, the period of lamellar structure is determined by intensity of non-local interactions, treated as squared gradient term in the density of Gibbs free energy ( ) ( )( ) ∫ ∇Ω++ Ω = 2 CKgCg dV G el .
Taking into account of gradient and elastic energy, as well as redistribution of vacancies, one has: V V AA B el B ABA C C DC CK C g LCj ∇+        ∇Ω−+ ∂ ∂ ∇=Ω * 2 2~µ , ,2~ * 2 V V BB B el B BA B C C DC CK C g LCj ∇+        ∇Ω−+ ∂ ∂ ∇−=Ω µ (25) ( ) uC C DCDC CK C g LCLCj V V BBAA ei ABBA V =∇ + −      ∇Ω−+ ∂ ∂ ∇−=Ω * * 2 2~µ - lattice shift velocity
