The purpose of this paper is to describe the basic reasons for obtaining narrower clad layers of CuZn10 alloy in regards to the central layer of steel strip DC04 are described. Some reasons for the reduction of the thickness of clad layers along the side edges of the strip are also described, as well as the change in the length of these parts with ...

In this paper the effect of different heat treatment (recrystallization, spheroidizing and normalizing) processes on microstructure of the steel DC04 intended for deep drawing is presented. The steel is cladded with CuZn10 layers by explosive welding. Since the melting temperature of alloy CuZn10 is significantly lower (melting range 1025-1045 oC) ...

The paper presents comparison of microstructure and hardness of Cu-Al-Ni shape memory alloy before and after heat treatment (quenching at 900°C/60 min/water and tempering at 300°C/60 min/water). Microstructural analysis was obtained by optical microscopy (OM) and scanning electron microscopy (SEM) equipped with energy dispersive spectrometr...

In this work we studied the response of newly developed armored steel plates PROTAC 500 to the ballistic testing with armored piercing bullets with a core of tungsten carbide, charge 7.62 mm. Interactions between the bullets and the steel plate was investigated by standard metallographic and mechanical testing methods. We were interested in the geo...
