Improved Microstructure and Increased Mechanical Properties of Additive Manufacture Produced Ti-6Al-4V By Interpass Cold Rolling
(University of Texas at Austin, 2013)
Distortion, residual stress and mechanical property anisotropy are current challenges in additive manufacturing (AM) of Ti–6Al–4V. High-pressure, interpass rolling was applied to linear
AM parts and resulted in a change ...
Utilizing Additive Manufacturing Techniques to Fabricate Weight Optimized Components Designed using Structural Optimization Methods
(University of Texas at Austin, 2013)
This paper describes a preliminary study of the application of structural optimization
techniques to the design of additively manufactured components, using load testing to failure
to establish true load carrying capacity. ...
Additive Manufacturing Laser Deposition of Ti-6Al-4V for Aerospace Repair Applications
(University of Texas at Austin, 2013-08-16)
Parts or products from high performance metal are very
expensive, partly due to the processing complexities during
manufacturing. The purpose of this project is to use additive
laser deposition and machining processes ...
The Effects of Processing Parameters on Defect Regularity in Ti-6Al-4V Parts Fabricated By Selective Laser Melting and Electron Beam Melting
(University of Texas at Austin, 2013-08-16)
Processing parameter has an important effect on Selective Laser Melting (SLM) and
Electron Beam Melting (EBM) processes. Defects are easily formed by deviating from optimized
processing parameters. This study purposely ...
Process Mapping of Transient Melt Pool Response in Wire Feed E-Beam Additive Manufacturing of Ti-6Al-4V
(University of Texas at Austin, 2013)
Wire feed electron beam additive manufacturing processes are candidates for
manufacturing and repair in the aerospace industry. In order to implement feedback or
feedforward control approaches, the time needed for a ...
Design of an Empirical Process Model and Algorithm for the Tungsten Inert Gas Wire+Arc Additive Manufacture of Ti-6Al-4V Components
(University of Texas at Austin, 2013)
In the wire+arc additive manufacture process parameters can be varied to achieve a wide range
of deposit widths, as well as layer heights. Pulsed Tungsten Inert Gas was chosen as the deposition
process. A working envelope ...
Understanding Ti-6Al-4V Microstructure Control in Additive Manufacturing via Process Maps
(University of Texas at Austin, 2013)
In direct metal additive manufacturing, the ability to predict and control as-deposited
microstructure can reduce the need for post-processing and speed up the qualification process.
In this work, a microstructure process ...
