In this study, the functionally graded materials (FGMs) bearing three layers were produced via hot pressing to investigate their ballistic performances against 7.62 mm armor piercing (AP) projectile. In the FGM samples, the bottom layer was considered as unreinforced AA7075 alloy, whereas the middle and top layers were made of the AA7075 composite layers having various proportions of B4C particles. Prior to the ballistic testing, the hardness change in the layers with respect to aging time at different temperatures was determined. And then, the ballistic testing of the samples was performed at a ballistic laboratory using 7.62 mm AP projectile. In the ballistic testing, five separate specimens for each FGM group having fixed composition and thickness were used. The experimental results showed that the ballistic impact resistance of the investigated FGMs increased with increasing boron carbide content and the thickness in the layers. Moreover, there were no separations observed between the layers in the failed samples.

Investigation on the ballistic impact behavior of various alloys against 7.62 mm armor piercing projectile DEMİR, TEYFİK; Ubeyli, Mustafa; Yıldırım, Raif Orhan (2008-12-01) In this study, impact behavior of the aluminum alloys of 7075 and 5083 and the high-strength low-alloy steel, AISI 4140 was investigated under 7.62 mm armor piercing (AP) projectile experimentally. Various heat treatments were applied to the alloys AISI 4140 and 7075 to see the effect of hardness and strength on their ballistic behaviors. Experimental results showed that among the investigated materials, the best ballistic performance was attained with the alloy, 7075-T651 which maintained the ballistic pro...
Effect of heat treatment on the formation of adiabatic shear bands in high strength steels impacted by AP projectiles Ubeyli, M.; DEMİR, TEYFİK; Yıldırım, Raif Orhan; Aycan, M. F. (2009-01-01) This study presents the effect of heat treatment on the adiabatic shear band formation in the steels AISI 4340 and DIN 100Cr6, which were impacted by 7.62 mm armour piercing (AP) projectile. Adiabatic shear band formation was investigated in the steel samples having different hardness levels and thickness values. Examinations were carried out using both optical and scanning electron microscopy to see the microstructural variations apparently. Moreover, microhardness measurements were also made to correlate ...
Numerical and experimental investigation of perforation of st-37 steel plates by oblique impact Öztürk, Gökhan; Yıldırım, Raif Orhan; Department of Mechanical Engineering (2010) In this thesis, it is aimed to determine the ballistic limit thicknesses of ST-37 steel plates under oblique impact of bullets having hard steel core (DIN 100Cr6 at 61-62 HRc) by using both experimental and numerical methods. In experimental part, angles of attack of the bullets are changed from 0 to 70 degrees by 10 degrees increments. Bullet velocities are measured for each shot just before the impact and they are found to be between 790-830 m/s. The minimum plate thickness that is not perforated and the ...
The effect of SN content and isothermal transformation temperature on the mechanical properties of austempered ductile cast iron Özcan, Alper; Atala, Haluk; Department of Metallurgical and Materials Engineering (2003) In this study the effects of Sn content and isothermal transformation temperature on the ultimate tensile strength (UTS), elongation and hardness of austempered ductile cast iron (ADI) was investigated. To determine the possible effect of Sn on these properties the Sn content of standard GGG30, GGG40 and GGG50 materials were taken as reference, whose chemical compositions vary from 0,016 to 0,050% in terms of Sn. However the Sn content was increased to a maximum of 0,26% for investigating the effect of Sn o...
The effect of double austenitization on the microstructure and toughness of AISI M2 high speed steel Ögel, Bilgehan (1998-06-01) In this study, the effect of double austenitization on microstructure and toughness of AISI M2 high speed steel was investigated. For double austenitization treatment, the specimens, which are hardened initially at 1220 degrees C and quenched in air, were hardened for a second time in the temperature range 1150 - 1050 degrees C. For comparison purposes, another set of specimens is austenitized singly in the temperature range 1150 - 1050 degrees C. Tempering process was carried out between 500 - 640 degrees ...
