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 structure-property relationships. Results showed that transformed bands were seen in the samples having the hardness of 49 and 59 HRC but deformed bands were observed in all investigated samples. Moreover, a fine grain structure with carbide precipitates was observed in the transformed bands.

EFFECT OF AGING ON MECHANICAL PROPERTIES OF Al-8Si-8Fe-1.4V/SiCp COMPOSITES Essari, A.; Sariuglo, F.; Petrovic, Z.; Sedmak, A.; Samardzic, I. (2016-01-01) In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of elasticity. The cast samples were solid soluted at 540 degrees C for one hour, then quenched in water to room temperature, and finally aged at 190 degrees C for 2, 4, 6, 8 and 10 hours for hardness test and at 195 degrees C for 2, 6 and 10 hours for bending strength determination.
Effect of microcapsulated red phosphorus on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral ATABEK SAVAŞ, Lemiye; Deniz, Tugba Kaya; Tayfun, Umit; DOĞAN, Mehmet (2017-01-01) The effect of microcapsulated red phosphorus (mRP) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) composites containing Huntite&hydromagnesite (HH). The flame retardant properties of TPU based composites were investigated using limiting oxygen index (LOI), vertical burning test (UL 94), thermogravimetric analysis (TGA) and mass loss calorimeter. The mechanical properties of composites were studied using tensile test and dynamic mechanical analysis (...
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 surface treatment on electrical conductivity of carbon black filled conductive polymer composites Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur (Wiley, 2007-06-05) Two different types of surface modifiers, 3-aminopropyltriethoxysilane and formamide, were applied to carbon black (CB) particles to lower electrical resistivity of polymer composites prepared by treated CB. Two different matrices, low-density polyethylene and nylon 6, were chosen to compound with surface modified CB. Surface energy of CB was increased by adding amine or amide functional groups during surface treatment of CB. According to electron spectroscopy for chemical analysis (ESCA), chemical modifica...
Effect of Sm on thermal and mechanical properties of Cu-Zr-Al bulk metallic glasses Sikan, Fatih; Atabay, S. E.; Motallebzadeh, A.; Özerinç, Sezer; Kalay, I.; Kalay, Yunus Eren (Elsevier BV, 2019-01-16) The effect of rare-earth (Sm) microalloying on the thermal stability and phase selection along with the effect of nanocrystallization on the mechanical properties of amorphous melt-spun ribbons of Zr50Cu40Al10, Zr49Cu39.2Al9.8Sm2 and Zr48Cu38.4Al9.6Sm4 alloys were investigated using differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), Vickers and nanoindentation hardness tests and micropillar compression analysis. XRD and TEM analyses showed that all samp...
