Effect of the as-built microstructure on the martensite to austenite transformation in a 18Ni maraging steel after laser-based powder bed fusion
(2021-10-01)
During laser-based powder bed fusion, the non-equilibrium solidification conditions promote local elemental segregation, leading to a characteristic microstructure composed of cellular walls. These walls can display either ...
Influence of the Processing Parameters on the Microstructure and Mechanical Properties of 316L Stainless Steel Fabricated by Laser Powder Bed Fusion
(2024)
Complex thermo-kinetic interactions during metal additive manufacturing reduce the homogeneity of the microstructure of the produced samples. Understanding the effect of processing parameters over the resulting mechanical ...
Microstructure effect on sliding wear of 316L stainless steel selectively laser melted
(2024)
Due to varying thermal cycles, the resulting microstructure of metal additive manufacturing differs from the conventionally processed counterpart alloys. Since the mechanical properties depend on the microstructure, the ...
In Situ High-Energy Synchrotron X-Ray Diffraction Reveals the Role of Texture on the Activation of Slip and Twinning during Deformation of Laser Powder Bed Fusion Ti–6Al–4V
(Wiley VCH Verlag, 2021-05)
The deformation behavior of Ti–6Al–4V processed by laser powder bed fusion (LPBF) is investigated by in situ high-energy synchrotron X-ray diffraction (HEXRD) during uniaxial compression. The initial microstructure of the ...
The Static and Fatigue Behavior of AlSiMg Alloy Plain, Notched, and Diamond Lattice Specimens Fabricated by Laser Powder Bed Fusion
(MDPI, 2018-04)
The fabrication of engineered lattice structures has recently gained momentum due to thedevelopment of novel additive manufacturing techniques. Interest in lattice structures resides not only in the possibility of obtaining ...
Morphologic changes and removal of debris on apical dentin surfaces after Nd : YAG laser and diode laser irradiation
(Mary Ann Liebert, Inc, 2008-06-01)
Objective: To verify the effects of laser energy on intracanal dentin surfaces, by analyzing the morphologic changes and removal of debris in the apical third of 30 extracted human teeth, prepared and irradiated with the ...
A Kalman-filtering-based Approach for Improving Terrain Mapping in off-road Autonomous Vehicles
(Springer, 2015)
The generation of accurate terrain maps while navigating over off-road, irregular terrains is a complex challenge, due to the difficulties in the estimation of the pose of the laser rangefinders, which is required for the ...
