YÜKSEK HIZLI ÇARPMA YÜKLERİNE MARUZ 6061 T651 ALÜMİNYUM LEVHALARIN KARAKTERİZASYONU
Kinetik enerjiye sahip mermilere karşı, tek veya çok katmanlı metal zırh sistemlerinin gösterdiği balistik davranış, çok sayıda deneysel, teorik ve sayısal çalışmayla araştırılmıştır. Bu çalışmada, 9 mm mermilerle üzerine atış yapılan 6061 T651 alüminyum levhalar incelenmiştir. Mikroyapı incelemesi optik mikroskop kullanılarak gerçekleştirilmiştir. Levhaların mukavemet davranışlarının belirlenmesinde mikrosertlik değerleri kullanılmıştır. Levha kalınlığı ve çarpma hızının mikroyapı üzerindeki etkisi değerlendirilmiştir. Çalışma sonucunda; ince levhaların, düşük çarpma hızlarında bile yüksek nüfuziyet derinliğiyle deformasyon sertleşmesine daha duyarlı olduğu, kalın levhaların ise düşük nüfuziyeti derinliğiyle termal yumuşamaya eğilimli olduğu değerlendirilmiştir. Maksimum sertlik değerleri her iki levha kalınlığında da çarpma bölgesinin hemen altında elde edilmiştir.

Characterization of 6061 T651 aluminum plates subjected to high-velocity impact loads
Ballistic response of single or multi-layered metal armor systems subjected to kinetic energy projectiles was investigated in many experimental, theoretical and numerical studies.In this study, 6061 T651 aluminum plates impacted by 9 mm bullets were investigated. Microstructural investigations have been carried out using optical microscopy. Microhardness values were used to determine the strength behavior of the plates. Influence of the plate thickness and impact velocity on the microstructure has been evaluated. It was concluded from the study that thinner plates are more prone to deformation hardening with high penetration depth values even at low impact velocities while thick plates are more susceptible to thermal softening with less penetration depths. Maximum hardness values were obtained just below the impact zone in both plate thicknesses.
