Study on Deformation Behavior of Ti6Al4V Parts Fabricated by Selective Laser Melting

Autor: Yang Tao, Liu Tingting, Liao Wenhe, Zhang Changdong, Duan Shengqin, Chen Xiangyuan

Publikováno v: MATEC Web of Conferences, Vol 237, p 01008 (2018)

During the Selective laser melting process, the accumulation of the residual stress caused by the excessive temperature gradients and the rapid solidification is the main factor causing deformation; and the wetting quality of the meltpool also has an
