Numerical and experimental determination of the residual stress state in multipass welded API 5LX70 plates

2014-01-01
Residual stres s distributions in multipass welded API SL X70 steel plates were determined by numerical and experimental methods. SYSWELD finite element software was used for numerical simulations. Microstructure variations were also considered for calculation of residual stresses. The continuous cooling transformation diagram was obtained via JMatPro software. The results showed that residual stress distribution is sensitive to number of weld passes, and microstructure changes. The simulation results were compared with those obtained by Magnetic Barkhausen Noise measurements on the welded plates. Simulation and experimental results gave qualitatively similar tendencies for the variation of the residual stress state.

Surucu, Gokhan; Gencer, Ayşenur; Wang, Xiaotian; Surucu, Ozge (Elsevier BV, 2020-04-05)
The structural, electronic, dynamic, and thermo-elastic properties of M2AlB (X = V, Nb, Ta) MAX phase borides were investigated using first principle calculations as implemented in the Vienna Ab-initio Simulation Package (VASP) with the generalized gradient approximation (GGA). The obtained structural properties and formation energies showed the thermodynamic stability and synthesizability of M2AlB. The electronic band structures were determined and they revealed that these compounds had a metallic characte...

The electronic band structures of InNxAs1-x, InNxSb1-x and InAsxSb1-x, alloys
Mohammad, Rezek; Katırcıoğlu, Şenay (Elsevier BV, 2009-02-05)
The band cap bowings of InNxAs1-x, InNxSb1-x, and InAsxSb1-x alloys defined by the optimized lattice constants are investigated using empirical tight binding (ETB) method. The present ETB energy parameters which take the nearest neighbor interactions into account with sp(3)d(2) basis are determined to be sufficient to provide a typical feature for the band gap bowings of the alloys. The band gap bowing parameter is found to be relatively large in both InNxAs1-x and InNxSb1-x compared to InAsxSb1-x alloys. M...
Nanocrystallization in Cu-Zr-Al-Sm Bulk Metallic Glasses
Sıkan, Fatih; Yaşar, Bengisu; KALAY, İLKAY (Springer Science and Business Media LLC, 2018-04-01)
The effect of rare-earth element (Sm) microalloying on the thermal stability and crystallization kinetics of melt-spun ribbons and suction-cast rods of Zr48Cu38.4Al9.6Sm4 alloy were investigated using differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), and atom probe tomography (APT). The XRD results of constant heating rate annealing indicated that amorphous Zr48Cu38.4Al9.6Sm4 melt-spun ribbons devitrifies into Cu2Sm at 673 K (400 A degrees C). The sequ...
Modeling of the atomic ordering processes in Fe3Al intermetallics by the Monte Carlo simulation method combined with electronic theory of alloys
Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Springer Science and Business Media LLC, 2003-12-01)
The evolution of atomic ordering processes in Fe3Al has been modeled by the Monte Carlo (MC) simulation method combined with the electronic theory of alloys in pseudopotential approximation. The magnitude of atomic ordering energies of atomic pairs in the Fe3Al system has been calculated by means of electronic theory in pseudopotential approximation up to sixth coordination spheres and subsequently used as input data for MC simulation for more detailed analysis for the first time. The Bragg–Williams long-ra...
