摘要: The interesting properties of Al 6061 aluminum foams have boosted the research on correlation between foam composition and morphology its mechanical response under dynamic conditions. In this study, ingots an 6061-T4 were sectioned analyzed in order to determine their microstructural morphological characteristics, then quasi-static tests (10−3 3 × 102 s−1) carried out material behavior. Dynamic tests, by using split Hopkinson bar, highlighted that studied is characterized a very good energy absorption capability, due ductile Nevertheless, conducted showed cell distribution affect behavior conditions which localized collapse may result decreased efficiency foam.
