Journal ArticleDOI
Technology of High-speed Direct Laser Deposition from Ni-based Superalloys
Olga Klimova-Korsmik,Gleb A. Turichin,Evgeniy Zemlyakov,Konstantin Babkin,Pavel Petrovsky,A. Travyanov +5 more
TL;DR: In this paper, high-speed direct laser deposition (HSDLD) is used to realize heterophase process during the manufacturing, which there is process takes place with a partial melting of powder.
Journal ArticleDOI
Analysis of distortion during laser metal deposition of large parts
TL;DR: In this paper, the effect of increasing cylinder radius is to increase residual radial displacement and curvature of the sidewall, and it was established that the highest tension hoop and axial stress amounted to 1.15-1.2 times of yield stress near the substrate.
