The ballistic performance of SiC-AA7075 functionally graded composite produced by powder metallurgy
ÜBEYLİ, MUSTAFA; BALCI, ERHAN; Sarikan, Bertan; ÖZTAŞ, MURAT ORHAN; CAMUŞCU, NECİP; Yıldırım, Raif Orhan; KELEŞ, Ömer (2014-04-01)
The potential of silicon carbide reinforced Functionally Gradient Material (FGM) to be used as armor material was investigated under the impact of armor piercing projectile. For this purpose, the SiC-Aluminum Alloy (AA) 70...
BALLISTIC PENETRATION OF HARDENED STEEL PLATES
Deniz, T.; Yıldırım, Raif Orhan (2013-04-26)
The change in ballistic performance of AISI 4340 steel plates with different thicknesses and varying hardness against 7.62 AP (Armor Piercing) projectiles is studied. Four different target plate hardnesses are chosen. The ...
On the ballistic performance of the AA7075 based functionally graded material with boron carbide reinforcement
Balci, E.; Sarikan, B.; ÜBEYLİ, MUSTAFA; CAMUŞCU, NECİP; Yıldırım, Raif Orhan (2013-01-01)
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, th...
DETRIMENTAL EFFECTS OF FLEXIBLE LINEAR SHAPED CHARGE (FLSC) TO NEARBY PLATES DUE TO VARYING BACKSPACE DISTANCE
Bingol, C. G.; Yıldırım, Raif Orhan (2011-09-16)
The objective of this study is to investigate the detrimental effects of a flexible linear shaped charge (FLSC) to variable thickness (3, 4 and 5 mm) Raex Ar 400 back plate and constant thickness (4.8 mm) Al-6061-T6 front ...
Investigation on the ballistic performance of a dual phase steel against 7.62 mm AP projectile
Ubeyli, Mustafa; DEMİR, TEYFİK; Deniz, Hueseyin; Yıldırım, Raif Orhan; KELEŞ, Ömer (2010-03-25)
Dual phase steels have the potential to reduce the weight of structural components because of the improved mechanical properties obtained from the two phases: soft ferrite and hard martensite. In this study, the ballistic ...
Effect of Hardness on the Ballistic Impact Behavior of High-Strength Steels Against 7.62-mm Armor Piercing Projectiles
DEMİR, TEYFİK; Ubeyli, Mustafa; Yıldırım, Raif Orhan (2009-03-01)
Ballistic performance of engineering materials should be known in selection of the most suitable armor material to protect civilian or military system with the lowest possible weight against various threats. In this study,...
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 ...
Response of Alumina/4340 Steel Laminated Composites against the Impact of 7.62 mm Armor Piercing Projectiles
DEMİR, TEYFİK; Ubeyli, Mustafa; Yıldırım, Raif Orhan; Karakas, M. Serdar (2009-01-01)
Laminated composite armors provide significant advantages to the defense systems when considering both the mobility and energy consumption. Among them, alumina faced laminated composite systems have been considered as stro...
