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 performance of a low carbon and low alloy steel was investigated in intercritically annealed conditions. To do this, intercritical heat treatments at three different temperatures were applied to the steel samples separately to get three groups of samples having various martensite volume fractions. The full annealing treatment was also performed on a fourth steel group sample for comparison with the dual phase samples. The ballistic testing was carried out using a 7.62 mm armor piercing (AP) projectile. The experimental results pointed out that the ballistic resistance of the dual phase steel increased by increasing martensite content. In addition, deformed shear bands and/or highly distorted microstructures were observed in all samples irrespective of heat treatment after the ballistic testing. Furthermore, there was a remarkable increase in the micro and macro hardness of the investigated steel samples due to the ballistic induced strain.

INVESTIGATION OF THE MICROSTRUCTURAL AND MECHANICAL PROPERTIES OF DP500 AND DP700 QUALITY STEELS WELDED WITH DIFFERENT HEAT INPUTS
Yılmaz, Kardelen; Ögel, Bilgehan; Batıgün, Caner; Department of Metallurgical and Materials Engineering (2023-1-25)
In this study, effect of different heat input values from different welding techniques on microstructural and mechanical properties of Dual Phase (DP) steel DP500 and DP700 are evaluated. The welding operations were carried out manually by using Tungsten Inert Gas Welding (TIG), Metal Active Gas (MAG) Pulse Arc Welding and MAG Cold Metal Transfer (CMT) arc methods with keeping different heat inputs. The specimens were welded under specified conditions. They were initially evaluated by metallographic methods...
A Study on Tensile Strength of Compacted Fine-Grained Soils
Dagar, Volkan; Çokça, Erdal (Springer Science and Business Media LLC, 2020-08-01)
The tensile strength of clay is a major mechanical parameter and the main controlling parameter of tensile crack development which is generally encountered in geostructures. In this experimental study, 8-shaped direct tensile test and split tensile test were used to measure the tensile strength of compacted clay soil. Unconfined compression tests on the same clay samples were also carried out. Tensile strength and unconfined compression test results were compared. Laboratory tests were performed on Ankara c...
INVESTIGATION OF PROCESS PARAMETERS ON PROPERTIES OF EPOXY BASED CATAPHORETIC COATINGS
Kaykaç, Nalan Gülçin; Bat, Erhan; Çırpan, Ali; Department of Polymer Science and Technology (2022-8-12)
Cataphoresis is the process of applying high-performance epoxy resins to metal surfaces in order to increase the corrosion resistance of metal materials by using electrochemistry principles. This process is widely used in automotive industry to ensure long time corrosion durability of the vehicles. The cataphoresis process proceeds in two main steps followed by baking. These processes can be roughly summarized as zinc phosphating and electrocoating. A multiple number of degreasing, washing and rinsing steps...
Investigation of crack growth along curved interfaces in L-shaped composite and polymers
Yavas, D.; Gozluklu, B.; Çöker, Demirkan (2014-01-01)
Delamination in unidirectional L-shaped composite laminates is modeled with two L-shaped polycarbonate plates bonded to each other where the effect of pre-crack length on the stability of the crack growth is investigated experimentally and computationally. In the experimental study, a unique testing fixture with a sliding platform is designed to create a pure vertical displacement to one of the arms. The full-field technique of photoelasticity is used in order to visualize isochromatic fringe pattern around...
Study of the structure of grafted copolymers on the base of butyl rubber and superhigh-molecular polyethylene
Aliguliev, R.M.; Gasanov, Kh.A.; Mehrabov, Amdulla (1992-04-01)
The specific features of structural changes of compositions of butyl rubber with superhighmolecular polyethylene produced by ultrasonic action were studied in the wide range of component ratios. The growth of interphase structures confirmed by IR- and NMR- spectroscopy, radiothermoluminescence, DTA and DSC methods was shown to improve the compatibility of these compositions. The presented data suggest that the formation of graft-copolymers on the base of PE and butyl rubber is highly affected by ultrasonic ...
