1. Interplay of particle shape and suspension properties: a study of cube-like particles
Published: 3/20/2015
Authors: Debra Jean Audus, Ahmed Mohamed Ahmed Hassan, Edward Joseph Garboczi, Jack F Douglas
Abstract: With advances in anisotropic particle synthesis, particle shape is now a feasible parameter for tuning suspension properties. However, there is a need to determine how these newly synthesized particles affect suspension properties and a need to solve ...

2. Characterization of Metal Powders Used for Additive Manufacturing
Series: Journal of Research (NIST JRES)
Report Number: 119.018
Published: 9/16/2014
Authors: John A. Slotwinski, Edward Joseph Garboczi, Paul E Stutzman, Chiara F Ferraris, Stephanie S Watson, Max A Peltz
Abstract: Additive manufacturing (AM) techniques can produce complex, high-value metal parts, with potential applications as critical parts such as those found in aerospace components. The production of AM parts with consistent and predictable properties ...

3. Porosity Measurements and Analysis for Metal Additive Manufacturing Process Control
Series: Journal of Research (NIST JRES)
Report Number: 119.019
Published: 9/16/2014
Authors: John A. Slotwinski, Edward Joseph Garboczi, Keith M. Hebenstreit
Abstract: Additive manufacturing techniques can produce complex, high-value metal parts, with potential applications as critical metal components such as those found in aerospace engines and as customized biomedical implants. Material porosity in these par ...

4. Application of physical and chemical characterization techniques to metallic powders
Published: 8/28/2013
Authors: Edward Joseph Garboczi, John A. Slotwinski, Max A Peltz, Chiara F Ferraris, Stephanie S Watson, Paul E Stutzman
Abstract: Systematic studies have been done on two different powder materials used for additive manufacturing: stainless steel and cobalt-chrome. The characterization of these powders is important in NIST efforts to develop appropriate measurements and standa ...

5. Physical and chemical characterization techniques for metallic powders
Published: 8/28/2013
Authors: John A. Slotwinski, Paul E Stutzman, Stephanie S Watson, Edward Joseph Garboczi, Max A Peltz, Chiara F Ferraris
Abstract: Systematic studies have been done on two different powder materials used for additive manufacturing: stainless steel and cobalt-chrome. An extensive array of characterization techniques were applied to these two powders. The physical techniques inclu ...

6. Porosity of Additive Manufacturing Parts for Process Monitoring
Published: 7/26/2013
Authors: John A. Slotwinski, Edward Joseph Garboczi
Abstract: Some metal additive manufacturing processes can produce parts with internal porosity, either intentionally (with careful selection of the process parameters) or unintentionally (if the process is not well understood.) Material porosity is undesirable ...

7. Modeling of the Influence of Transverse Cracking on Chloride Penetration into Concrete
Published: 4/23/2013
Authors: Dale P Bentz, Edward Joseph Garboczi, Yang Lu, Nicos Martys, Aaron Richard Sakulich, William Jason Weiss
Abstract: Concrete service life models have proliferated in recent years due to increased interest in designing infrastructure elements with at least a 75-year service life, along with greater emphasis on life cycle costing in general. While current models con ...

8. Identifying improved standardized tests for measuring cement particle size and surface area
Published: 4/1/2013
Authors: Chiara F Ferraris, Edward Joseph Garboczi
Abstract: The Blaine fineness (Blaine) of a cement powder is a single parameter that is meant to characterize the specific surface area of a cement, and is assumed to be linked to physical and mechanical properties such as strength, setting time, and rheology. ...

10. Modeling Chloride transport in Cracked Concrete: A 3-D image-based microstructure simulation
Published: 10/3/2012
Authors: Edward Joseph Garboczi, Dale P Bentz, Jeffrey M. Davis, Yang Lu
Abstract: The prediction of the service life of concrete materials is difficult, mainly because of their complex heterogeneous microstructure and their random nature. Studying the presence of cracks in concrete and their effect on chloride transport and reacti ...
