A micro-damage investigation on a low-alloy steel tested using a 7.62-mm AP projectile | [Raziskava mikropoškodb malolegiranega jekla po preizkusu s kroglo AP 7,62 mm]
Demir, Teyfik; Übeyli, Mustafa (INST ZA KOVINSKE MATERIALE I IN TEHNOLOGIE, 2011)Low-alloy steels have been widely used as an armor material in defense systems due to their superior mechanical and weldability properties. In this study, microdamage formation in an AISI 4140 steel, which was hit by 7.62-mm ... -
Effect of the martensite volume fraction on the machining of a dual-phase steel using a milling operation
Topçu, Okan; Übeyli, Mustafa; Acır, Adem (INST ZA KOVINSKE MATERIALE I IN TEHNOLOGIE, 2011)Dual-phase steels are attractive because of their good combination of strength and ductility. However, an increase in the martensite content will decrease the steel's machinability significantly. Therefore, optimum cutting ... -
Investigation on the behaviour of the functionaly gradient material consisting of boron carbide and aluminum alloy
Sarıkan, Bertan; Balcı, Erhan; Übeyli, Mustafa; Camuscu, Necip (INST ZA KOVINSKE MATERIALE I IN TEHNOLOGIE, 2012)In the current study the effect of different temperatures on the aging behaviour of a functionally gradient material was investigated to observe the variation of hardness with respect to the aging time. To do this, the ... -
Investigation on the rheological behavior of Al-Fe-V-Si/Alumina composite powders
Turan, E.; Uslan, I.; Übeyli, Mustafa (REDAKCIA KOVOVE MATERIALY,, 2012)In this paper, the rheological properties of the feedstocks of Al-Fe-V-Si and Al-Fe-V-Si composites reinforced with alumina were investigated. The feedstocks, containing four different types of powder (Al-Fe-V-Si, Al-Fe-V-Si ...
