WAAM-fabricated Inconel alloy has comparatively lower residual stresses levels , but it is more susceptible to process defects such as delamination , buckling and warping , since its residual stress is usually higher than the yield stress .
 material: Inconel alloy; machanical property: residual stresses; concept or principle: process defects; material: as; machanical property: buckling; concept or principle: warping; machanical property: residual stress; machanical property: yield stress
