An Experimental-Numerical Investigation of Heat Transfer During Selective Laser Melting
(University of Texas at Austin, 2015)
The heat transfer in and around a part being fabricated via Selective Laser Melting (SLM) is
numerically simulated while considering the surrounding powder bed modeled to have an
effective thermal conductivity. By ...
Processing ODS Modified IN-625 Using Selective Laser Melting
(University of Texas at Austin, 2015)
Increasing the operating temperatures of power plant turbine generators is a universal method
to increase the efficiency of steam and gas turbines. However, operating a plant at higher
temperatures poses extreme challenges ...
Microstructure and Mechanical Characterisation of SLM Processed Haynes® 230®
(University of Texas at Austin, 2015)
Selective Laser Melting (SLM) enables the production of complex near-net-shaped parts
especially out of difficult to machine Nickel based alloys like Haynes®
230®. However, exact
knowledge of the SLM processing windows ...
Fatigue Behavior of Selective Laser Melted 17-4 PH Stainless Steel
(University of Texas at Austin, 2015)
In this investigation, fully-reversed strain-controlled fatigue tests were conducted on
Selective Laser Melted (SLM) 17-4 PH stainless steel (SS). Cylindrical 17-4 PH rods were
fabricated vertically-upward using optimized ...
The Effects of Heat Balance on the Void Formation within Marage 300 Processed by Selective Laser Melting
(University of Texas at Austin, 2015)
This contribution shows the results of a study that was conducted on the effects of varying
selective laser melting (SLM) process parameters on the formation of microstructural voids
within a maraging steel (type: Marage ...
Prediction of Porosity in SLM Parts Using a MARS Statistical Model and Bayesian Inference
(University of Texas at Austin, 2015)
Predictive models that establish a linkage between process parameters and part properties
have been identified as a high priority research need in Additive Manufacturing. We work with
a Multivariate Adaptive Regression ...
Selective Laser Melting of a Bismuth Telluride Thermoelectric Materials
(University of Texas at Austin, 2015)
Selective Laser Melting (SLM) technology is a rapidly growing solid freeform fabrication
tool because it is cost effective, reduces production time of complex shapes, and accommodates a
range of material systems such as ...
