Abstract

In this study, the impact behaviors of AlSi7 foams under low-velocity impact energies were investigated. The low-velocity impacts (1,2 - 3 ms-1) were applied to the samples with 55x55x20 mm dimensions using the weight drop test machine. The impact tests were performed until perforation took place on a sample and so penetration and perforation impact behavior were analyzed. The changes in the internal structures of the samples after the impact were observed in the macro level.

Özet

Bu çalışmada AlSi7 köpüklerin düşük hızlı darbe enerjileri altındaki penetrasyon davranışları incelenmiştir. Bu amaçla toz metalurjisi yöntemi ile üretilen 55x55x20 mm boyutlarında Al köpüklere ağırlık düşürme test cihazı kullanarak farklı hızlarda (1,2 - 3 ms-1) darbeler uygulanmıştır. Bir numune üzerinde delinme meydana gelene kadar yapılan darbe testleri ile saplanma ve delinme darbe davranışları incelenmiştir. Darbe sonrası numunelerin içyapılarında meydana gelen değişiklikler makro boyutta incelenmiştir.
