The microstructure and mechanical properties of selectively laser melted AlSi10Mg: The effect of a conventional T6-like heat treatment
TL;DR: In this paper, the nano-, micro-, and macro-scale mechanical properties of selective laser melting (SLM) AlSi10Mg were examined and correlated to the generated microstructure.

Plasticity and Damage in Aluminum Syntactic Foams Deformed under Dynamic and Quasi-Static Conditions
TL;DR: In this paper, synthetic foams were fabricated by liquid metal infiltration of commercially pure and 7075 aluminum into preforms of hollow ceramic microspheres, which exhibited peak strength during quasi-static compression ranging from −100 to −230 MPa, while dynamic compression loading showed a 10-30% increase in peak strength magnitude, with strain rate sensitivities similar to those of aluminum-matrix composite materials.

Comparison of compressive properties of layered syntactic foams having gradient in microballoon volume fraction and wall thickness
Nikhil Gupta,William Ricci +1 more
TL;DR: In this article, the volume fraction is used as an additional parameter for controlling the properties of syntactic foams, and a FGSF is fabricated that is based on the microballoon wall thickness variation along the specimen length.

Compression behaviors of cenosphere–pure aluminum syntactic foams
TL;DR: In this article, a new method was established to predict the compressive strength of cenosphere-aluminum syntactic foams, showing the relation between the relative wall thickness of the cenopshere and the Compressive Strength of such foams.

Metallic foams: their production, properties and applications
G. J. Davies,Shu Zhen +1 more
TL;DR: In this paper, the properties of metallic foams, such as mechanical properties, energy absorbing characteristics, permeability, acoustical properties and conductivities, are described and examples of the use of metallic foam in practice have been given to indicate the wide range of circumstances in which metallic foam can be used.

Deformation and energy absorption diagrams for cellular solids
TL;DR: In this article, the mechanical properties of three types of cellular solids (flexible, plastic and brittle) have been measured as a function of density; the results are compared with models for the stiffness, strength and densification; and constitutive laws are developed.

Deformation characteristics of metal foams
John Banhart,Joachim Baumeister +1 more
TL;DR: In this paper, the deformation behavior of metal foams is investigated by uniaxial testing and a series of measurements were carried out where the orientation of the outer skin and the foaming direction were varied.
