“…These strains were used as suggested by many researchers to investigate energy absorption capacity of porous metals. 9,16,17) The effect of relative density of porous sintered fiber metals on the energy absorption efficiency and energy absorption capacity is shown in Table 1. The results indicated that relative density plays an important role in energy absorption capacity of porous sintered fiber metals during compression.…”

Porous sintered fiber metals with different relative densities were successfully prepared by using vacuum sintering process. Compressive property and energy absorption capacity of porous sintered fiber metals were investigated under quasi-static conditions. The results indicate that compressive stress-strain curves of porous sintered fiber metals exhibit three distinct deformation regions: elastic region, stress plateau region and densification region. The compressive property of porous sintered fiber metals can be interpreted by the Gibson-Ashby theory. It is found that compressive property, energy absorption capacity and energy absorption efficiency of porous sintered fiber metals present significant relative density sensitivity. The energy absorption capacity of the samples rises from 7.17 to 25.75 MJÁm À3 when relative density increases from 0.177 to 0.355.

“…As development of material science technology, it has stepped out of the many kinds of the building materials, such as ceramics, the metal materials, etc. Foamed metal materials is a metal or alloy in the macro and micro pore volume fraction （porosity） larger than 15% rate after the will of opening to the existence of some wonderful functions of the performance, thus a new type of functions and structure material [1,2] exceptionally lightweight materials possess unique combinations of properties, such as impact energy absorption capacity, air and water permeability, unusual acoustic properties, low thermal conductivity and good electrical insulating properties. There has been a strongly growing demand for the use of foamed metal, for aerospace, automotive and railway applications.…”

ABSTRACT This work reports the technology of preparation about foamed Zn-Al eutectoid alloy, which were prepared by an air pressure infiltration process using NaCl crystals as place holders. The method consists of five sequential processes: particles preprocessing, preparing preform, preheating, infiltration casting, machining and cleaning. The porosity of foamed Zn-Al eutectoid alloy is 61%. The mean diameter of macroscopic pore is on the order of a millimeter (1.0 mm) in the foamed Zn-Al eutectoid alloy with open-pore structure.

Fabrication and Characterization of Tensile Deformation of Tin-Lead Open Cell Foams

2015

View full text Add to dashboard Cite

This study is devoted to the investigation of metallic foams based on tin-lead alloy (with 50% of tin content) by the liquid metal inltration process. Uniaxial tensile tests were performed at room temperature in order to study mechanical properties of foams of dierent relative density and cell size. The samples were concurrently characterized on a microscopic scale (metallography and hardness) in order to link the morphological and mechanical characteristics of the constitutive phases.
