Residual stresses in LENS-deposited AISI 410 stainless steel plates

“…The residual stress in LENS components has been investigated both by experiments [11][12][13][14] and modeling [10,15,16]. Rangaswamy et al [11,12] measured the residual stresses in LENS components using neutron diffraction and contour method.…”

Microstructure and mechanical properties of a graded structural material

“…As the wall grows up further, the temperature of the building becomes higher continuously due to the heat dissipation barrier of the substrate and previous layers, and the cooling rate is lowered [23]. Less heat is transferred from the molten pool to the deposited materials at the same time and the maximum temperature of the molten pool increases [24], which will strengthen the re-melt effect and increase the depth of the molten pool [25]. Finally, all equiaxed grains formed at the top of the molten pool are re-melted and epitaxial growth of columnar grains dominates again.…”

Modeling of the Effect of Path Planning on Thermokinetic Evolutions in Laser Powder Deposition Process

“…Kaplan and Groboth [1] studied analytically the effect of the mentioned parameters on the clad layer formation and overlapping of tracks. Labudovic et al [2] studied the effect of process parameters on the formation of residual stress along the height of a single-bead wall deposition. Similar work was performed by Wang and Felicelli, [3] who investigated the effect of the laser power and traverse speed on the material phase transformations during the process.…”
