Metal Foams A Design Guide

A comprehensive DFT study on the thermodynamic and mechanical properties of L12-Al3Ti/Al interface

Based on the finite element analysis for the combined rolling-extrusion process, the stress-strain state, force on the tool, and the moments on the rolls are calculated as a function of the tool temperature and the rotational speed of the rolls. The calculations are performed for an Al – Ti – B system alloy containing 5% titanium and 1% boron, widely used in the industry for melt modification when casting ingots of aluminum alloys. The authors proposed ligature rods from this alloy to be produced by the method of combined rolling-extruding (CRE), which has significant advantages in comparison with the traditional technologies of continuous casting-rolling and discrete extruding. Therefore, for the design of technology and equipment for combined processing, it is necessary to have preliminary design data on the temperature-velocity conditions and energy-force parameters of the metal deformation process. For 3D modeling in a software package SolidWorks® the model of the combined rolling-extruding process was created, which was imported into the package DEFORMTM. The simulation process of producing a rod diameter of 9.5 mm by installing rolls with diameters of 462 mm and a protrusion stream 394 mm with rolling reduction of 50% drawing ratio during extruding 6.2 at the rotation speed of 9 rpm data obtained by the temperature distribution metal, strain rates, normal contact stresses on the tool and internal stresses in the metal. In addition, graphs of the change in the forces and moments of rolling acting on the rolls are plotted, depending on the rotational speed of the rolls and the required power of the drive motor is calculated. The obtained data were used in the design of new industrial equipment for combined rollingextruding of aluminum alloys and experimental studies, which confirmed the adequacy of the obtained modeling results.

Analysis of energy-force parameters of combined processing for receiving modifying bars from Al – 5 Ti – 1 B alloy

Closed-cell aluminum alloy (A356) foams with different percentages of Al-Ti-B are prepared by melt foaming method, using Ca and TiH 2 as thickening agent and foaming agent, respectively. SEM and Quasi-static compression tests are performed to investigate the effect of Al-Ti-B on the microstructure and compressive properties of aluminum alloy (A356) foams. The results show that foams with Al-Ti-B percentage of 0.3 wt.% possess good combinations of micro hardness, yield strength, plateau strength, densification strain and energy absorption capacity under the present conditions. The reasons are mainly due to the foams with Al-Ti-B percentage of 0.3 wt.% possess optimal eutectic Si morphology (with eutectic Si existing in the forms of particles or short fiber).

The microstructure and compressive properties of aluminum alloy (A356) foams with different Al-Ti-B additions

Closed-cell aluminum foam with different percentages of Cu was prepared by melt foaming method.The effect of Cu element on the quasi-static compressive properties of aluminum foam was investigated, both under as-cast and heat-treated conditions. The results showed that Cu element distributed in cell wall matrix mainly in the forms of Al-Cu solid solutions and AlCu3, Al6.1Cu1.2Ti2.7 intermetallics. Meanwhile, Cu-containing foams possessed much higher compressive strength than the commercially pure aluminum foams. Additionally, proper heat treatment could further improve the yield strength of Cu-containing foams and the effect of aging treatment was more obvious than the homogenizing heat treatment under the present conditions and the reasons were discussed.
