Design of a Micro-Hopper Array for Multi-Material Powder Deposition
(2001)
We present a concept for creating patterned beds of multi-material powder particles using
an array of small-scale hoppers. Using this technique, we propose that to place fine particles of
multiple fluidized powders ...
Direct Selective Laser Sintering and Containerless Hot Isostatic Pressing for High Performance Metal Components
(1997)
A novel net shape manufacturing method known as SLSIHIP that
combines the strengths ofselective laser sintering (SLS) and hot isostatic pressing
(HIP) is presented. Direct selective laser sintering is a rapid ...
Direct Laser Fabrication of High Performance Metal Components Via SLS/HIP
(1999)
Recent research in the area of direct freeform fabrication of components via selective laser
sintering/hot isostatic pressing (SLS/HIP) has focused on the processing of Alloy 625. Alloy 625
is a nickel-based superalloy ...
Processing of Titanium Net Shapes by SLS/HIP
(1998)
SLS/HIP is a hybrid direct laser fabrication method that combines the strengths of
selective laser sintering (SLS) and hot isostatic pressing (HIP). SLS can produce complex
shaped metal components with an integral, gas ...
Modeling and Characterization of Microstructure Evolution in Single-Crystal Superalloys Processed through Scanning Laser Epitaxy
(University of Texas at Austin, 2015)
This paper focuses on microstructure evolution in single-crystal alloys processed through
scanning laser epitaxy (SLE); a metal powder-bed based additive manufacturing technology
aimed at the creation of equiaxed, ...
Computational Modeling and Experimental Validation of Melting and Solidification in Equiaxed Superalloys Processed through Scanning Laser Epitaxy
(University of Texas at Austin, 2015)
This paper focuses on simulation-based optimization of the Scanning Laser Epitaxy (SLE)
process applied to gas turbine hot-section components made of nickel-base superalloys. SLE
creates equiaxed, directionally-solidified ...
Carbide Formation in Nickel-Base Superalloy MAR-M247 Processed Through Scanning Laser Epitaxy (SLE)
(University of Texas at Austin, 2016)
Nickel-base superalloys develop high-temperature strength primarily due to the solid-solution-strengthening and the precipitation-strengthening mechanisms typically through cobalt/chromium
and aluminum/titanium respectively. ...
Microstructural Characterization of MAR-M247 Fabricated Through Scanning Laser Epitaxy
(University of Texas at Austin, 2016)
Nickel-base superalloys are extensively used to produce gas turbine hot section components as
these alloys offer improved creep strength and higher fatigue resistance compared to other alloys
due to the presence of ...
