Abstract

Additively Manufactured Interpenetrating Composites (AMIPCs) are a relatively new metal-metal chain composite in development for use in high energy absorption systems. In this system, reinforcing phase of additively manufactured continuous lattice configurations 316L austenitic stainless-steel is in melt infiltrated with a matrix phase of A356 aluminum-silicon casting alloy. Measurements and observations of this material system have shown that weakly bonded or open/porous interface between the reinforcement and matrix phases exhibits dramatically different mechanical properties of AMIPCs, which is not currently well understood. In this work, Finite Element Models (FEM) are used to model the effects of interfaces between the composite phases. Mechanical tensile tests measurements of various composite volume fractions and varying degrees of casting infiltration are also examined and used to show consistency with the FEM results. The outcome provides insight into material design criteria and performance predictions for new hybrid material systems with exceptional damage tolerance.

Hypervelocity Impact of Additively Manufactured A356/316L Interpenetrating Phase Composites

Conference French, Matthew; Yarberry, William; Pawlowski, Alex; ...

We have examined the hypervelocity impact response of targets made from monolithic A356 and 316L, as well as an additively manufactured A356/316L interpenetrating phase composite. 1.9 mm diameter spherical projectiles made from 2017 aluminum were fired at velocities of 5.9-6.1 km/s, allowing for the observation of multiple types of macro- and microstructural damage within each target. The macroscopic cratering damage to the A356/316L composite resembles that of the A356, but observations of both the cross section and the microstructural damage suggest that the A356/316L composite may be more resistant to spalling than A356 shielding with the same areal density.

Mesostructure and porosity effects on the thermal conductivity of additively manufactured interpenetrating phase composites

Journal Article Moustafa, Abdel; Dinwiddie, Ralph; Pawlowski, Alexander; ... - Additive Manufacturing

In this paper, we have investigated the relationship between structure and thermal conductivity in additively manufactured interpenetrating A356/316L composites. We used X-ray microcomputed tomography to characterize the pore structure in as-fabricated composites, finding microporosity in both constituents as well as a 50 μm thick layer of interfacial porosity separating the constituents. We measured the thermal conductivity of a 43 vol% 316L composite to be 53 Wm^-1K^-1, which is significantly less than that predicted by a simple rule-of-mixtures approximation, presumably because of the residual porosity. Motivated by these experimental results we used periodic homogenization theory to determine the combined effects ofmore »« less

Additive manufactured interpenetrating phase composite

Patent Pawlowski, Alex; Shyam, Amit; Splitter, Derek; ...

A method for preparing metal/metal interpenetrating phase composites is provided. The method includes forming a preform using additive manufacturing. The preform defines a materially continuous three-dimensional open-cell mesh structure. The preform includes a first metal having a melting point. The method further includes pre-heating the preform to a first temperature less than the melting point of the first metal. The method includes infiltrating the preform with a second metal in liquid form. The second metal has a melting point lower than the melting point of the first metal. The method also includes allowing the second metal to cool and formmore »« less

Interface and tensile behavior of squeeze cast AC8A-Al{sub 2}O{sub 3} composite

Journal Article Baik, K; Lee, G; Ahn, S - Scripta Metallurgica et Materialia

Squeeze casting is a processing technique to fabricate parts of low melting point alloys under high pressure of 30--150 MPa, which can be applied for the manufacture of metal matrix composite having low wettability between melt and reinforced fibers. The mechanical properties of the composite highly depend on the processing parameters such as infiltration pressure, preform temperature, and superheating of the melt. Microstructure and property of the interfacial region of fiber and matrix are known to play a major role in determining the mechanical properties of the metal matrix composite. For a composite material with high stiffness and high strength,more »« less

Fiber reinforcement of investment cast parts

Conference Nolte, M; Neussl, E; Schaedlich-Stubenrauch, J; ...

For 3 years now the Foundry-Institute (Giesserei-Institut) of the Aachen Institute of Technology has worked on the development of a new, low-cost production process for longfiber-reinforced light alloy components. The process baseline is oriented on the precision casting process in its investment casting mode, also known as lost wax process. The investment casting process is well known as a typical near-net-shape process for the manufacture of high-quality cast components, predominantly for applications in the aerospace industry (structured components, turbine blades and parts etc.) and enjoys significant growth rates during the last decades. After preliminary studies on the modification of singlemore »« less
