To ensure the robust design freedom of metallic additive manufacturing, fatigue properties and dimensional limitation as-built components by laser powder bed fusion (PBF-LB) are investigated. Fully reversed strain-controlled tests were carried out on tubular specimens with different wall thicknesses, 1 mm 2 mm, for purpose studying thin-wall effect without having risk buckling problem during compression. Two wrought conditions also enclosed as a comparison, which cold worked (CW) solution...
Laser powder bed fusion (LPBF) of Ni-based superalloys shows great potential for high temperature applications, example, as a burner repair application gas turbines where the thin-walled structure is important. It motivates this work to investigate evolution microstructure and anisotropic mechanical behavior when plate-like specimens are built with thickness from 4 mm down 1 mm. By performing texture analysis using neutron diffraction, clear transition in fiber <011> <001> indicated specimen...
To improve the understanding of high temperature mechanical behaviours LPBF Ni-based superalloys, this work investigates influence an elongated grain structure and characteristic crystallographic texture on anisotropic tensile in Hastelloy X (HX) at 700 °C. Two types loading conditions have been examined to analyse anisotropy related building direction (BD), including vertical (loading direction//BD) horizontal ⊥ BD). probe short-term creep behaviours, slow strain rate testing (SSRT) has...
The high residual stress (RS) in the components manufactured by laser powder bed fusion (LPBF) can be detrimental to mechanical properties, especially fatigue performance. Stress relief (SR) heat treatment is commonly applied on as-built for relaxation. Hence, effect of SR (600 ˚C/4 hours) fully reversed low cycle (LCF) behaviours LPBF stainless steel 316L (SS 316L) was investigated this study. depth profiles RS distribution across specimen were measured neutron diffraction, and a...
This work investigates the influence of elongated grain structure and characteristic texture on anisotropic tensile behaviours in LPBF Hastelloy X (HX) at elevated temperature. Four different loading conditions were examined, including vertical (loading direction // building direction) horizontal ⊥ two strain rates, 10 -5 /s -3 /s. The slow rate was applied for purpose probing short-term creep behaviours. At rate, a continuous softening due to damage takes place right after yielding,...
