“…Subsequently, the research expanded to improving forecast models for warpage, based on general beam theory [73]. Other techniques encompass neutron diffraction (ND) [22][23][24]74], X-ray diffraction (XRD) [25][26][27]75], contour method [13,[76][77][78] hole drilling methods [32], thermomechanical coupling model [79], digital image correlation (DIC) [80], deep hole drilling (DHD) [81], Operando synchrotron or synchrotron X-ray diffraction (SXRD) [82,83]. The selection of the methods depends on elements such as material, component size, geometry, and the level of accuracy required for the measurement.…”

“…A amostra após DED apresenta TR compressiva, que está associada ao gradiente de temperatura da poça de fusão (∆T ao redor do feixe de laser reduz a resistência do material e promove a expansão da camada, induzindo tensão residual compressiva na camada superficial superior) (MERCELIS; KRUTH, 2006). Tal estado de tensão de compressão inicial de componentes de aço inoxidável 316L fabricados por DED também é relatado por Piscopo, Salmi e Atzeni (2021) e Kumaran et al (2021). Este estado de compressão está associado a parâmetros de deposição (potência do laser, velocidade de deslocamento do cabeçote de deposição, sobreposição de camadas, entre outros).…”
