On the Prediction of Uniaxial Tensile Behavior Beyond the Yield Point of Wrought and Additively Manufactured Ti-6Al-4V
Integrating Materials and Manufacturing Innovation - Tập 11 - Trang 327-338 - 2022
In this paper, phenomenological relationships are presented that permit the prediction of the plastic regime of stress–strain curves using a limited number of parameters. These relationships were obtained from both conventional (wrought + β annealed) and additively manufactured (i.e., “3D printed”) Ti-6Al-4V. Three different methods of additive manufacturing have been exploited to produce the mate...... hiện toàn bộ
Temperature-Dependent Material Property Databases for Marine Steels—Part 5: HY-80
Integrating Materials and Manufacturing Innovation - - Trang 1-28 - 2023
Integrated Computational Materials Engineering (ICME)-based tools and techniques have been identified as the best path forward for distortion mitigation in thin-plate steel construction at shipyards. ICME tools require temperature-dependent material properties—including specific heat, thermal conductivity, coefficient of thermal expansion, elastic modulus, yield strength, flow stress, and microstr...... hiện toàn bộ
ICME Framework for Simulation of Microstructure and Property Evolution During Gas Metal Arc Welding in DP980 Steel
Integrating Materials and Manufacturing Innovation - Tập 9 - Trang 228-239 - 2020
An integrated computational materials engineering (ICME)-based workflow was adopted for the study of microstructure and property evolution at the heat-affected zone (HAZ) of gas metal arc-welded DP980 steel. The macroscale simulation of the welding process was performed with finite element method (FEM) implemented in Simufact Welding® software and was experimentally validated. The time–temperature...... hiện toàn bộ
Material Property Prediction Using Graphs Based on Generically Complete Isometry InvariantsAbstract The structure–property hypothesis says that the properties of all materials are determined by an underlying crystal structure. The main obstacle was the ambiguity of conventional crystal representations based on incomplete or discontinuous descriptors that allow false negatives or false positives. This ambiguity was resolved by the ultra-fast pointwise dist... ... hiện toàn bộ

Combining material and model pedigree is foundational to making ICME a reality
Integrating Materials and Manufacturing Innovation - Tập 4 - Trang 37-62 - 2015
With the increased emphasis on reducing the cost and time to market of new materials, the need for analytical tools that enable the virtual design and optimization of materials throughout their processing-internal structure-property-performance envelope, along with the capturing and storing of the associated material and model information across its life cycle, has become critical. This need is al...... hiện toàn bộ

Modeling Strain Localization in Microtextured Regions in a Titanium Alloy: Ti–6Al–4V
Integrating Materials and Manufacturing Innovation - Tập 8 - Trang 455-467 - 2019
Large and highly textured regions, referred to as macrozones or microtextured regions, with sizes up to several orders of magnitude larger than those of the individual grains, are found in dual-phase titanium alloys as a consequence of the manufacturing process route. These macrozones have been shown to play a critical role in the failure of titanium alloys, specifically being linked to crack init...... hiện toàn bộ
3D Minimum Channel Width Distribution in a Ni-Base Superalloy
Integrating Materials and Manufacturing Innovation - Tập 12 - Trang 27-40 - 2023
The strength of a Ni-base superalloy depends strongly on its microstructure consisting of cuboidal
$${\gamma }^{^{\prime}}$$
precipitates surrounded by narrow channels of
$$\gamma $$
matrix. Accor...... hiện toàn bộ
Extraction of Process-Structure Evolution Linkages from X-ray Scattering Measurements Using Dimensionality Reduction and Time Series Analysis
Integrating Materials and Manufacturing Innovation - Tập 6 - Trang 147-159 - 2017
The rapid development of robust, reliable, and reduced-order process-structure evolution linkages that take into account hierarchical structure are essential to expedite the development and manufacturing of new materials. Towards this end, this paper lays a theoretical framework that injects the established time series analysis into the recently developed materials knowledge systems (MKS) framewor...... hiện toàn bộ
Coupled Process Modeling of Flow and Transport Phenomena in LCM Processing
Integrating Materials and Manufacturing Innovation - Tập 11 - Trang 363-381 - 2022
In Liquid Composite Molding (LCM) processes, dry fabric preforms are impregnated with a thermoset resin in a closed mold to fabricate a composite. The resin impregnation process is usually accompanied by other phenomena. In this work, we concentrate on transport phenomena such as convection of heat, cure and volatiles that impact the filling process and/or the quality of the manufactured part. Con...... hiện toàn bộ
