چکیده

V. Marušić, I. Samardžić, I. Opačak. Faculty of Mechanical Engineering in Slavonski Brod University of Osijek, Croatia. The research investigated properties of aluminum bronze welded to structural steel St 52-3 N. Surface material CuAl-A3 was welded in one and two layers. There were dimension, metallographic examination of structures and hardness measured before and after heat treatment and after pressurization of tested specimens. It was determined that the specimens achieved the best performance by welding two layers of surface material, by postweld heat treatment and by “hammering“.

بررسی روند تشکیل ترکیبات اکسیدی در آثار برنزی با استناد به مطالعات میکروسکوپی

Due to the complex corrosion mechanism of the bronze objects, explaining the structure of different layers of corrosion in these objects at microscopic levels is possible. Typically copper oxide(I) is the first corrosion layer on surface of bronze objects that are excavated of historical sites. However, depending on the environmental conditions، various forms of corrosion layer of tin or copper...

INVESTIGATING THE fFORMATION OF INTERMETALLIC COMPOUNDS AND THE VARIATION OF BOND STRENGTH BETWEEN Al-Cu LAYERS AFTER ANNEALING IN PRESENCE OF NICKEL BETWEEN LAYERS

In the present study, the effect of post-rolling annealing heat treatment on the formation of intermetallic compounds between Al-Cu strips, in the presence of nickel coating on the Cu strips, was investigated. In addition, the effect of post-rolling annealing and intermetallic compounds on the bond strength of Al-Cu strips was evaluated. In order to prepare samples, Cu strips were coated with n...

TRANSFORMATION BEHAVIOR OF NiTi SHAPE MEMORY ALLOYS TREATED BY THERMOMECHANICAL PROCESSING USING DSC

Abstract: In the present study the effect of thermomechanical treatment (cold work and annealing) on the transformation behavior of NiTi shape memory alloys was studied. Differential scanning calorimetry was used to determine transformation temperature and its relation to precipitates and defects. Three alloys including Ti-50.3at.% Ni, Ti-50.5at.% Ni (reclamated orthodontic wires) and 50.6at...

The Effects of Martensite Thermomechanical Parameters on the Formation of Nano/Ultrafine Grained Structure in 201LN Stainless Steel

In this study, the effects cold rolling and annealing parameters during thermomechanical processing of the AISI 201LN stainless steel were investigated. The cast samples were homogenized, hot-rolled and solution-annealed to acquire a suitable microstructure for the subsequent thermomechanical treatment. Unidirectional and transverse multi-pass cold rolling at 25, 0 and -15 °C was carried out to...

An Investigation on Mechanical Properties of Ultrafine Grained 316 Stainless Steel by Thermomechanical Treatment

In this paper, an advanced thermo-mechanical treatment was conducted on AISI 316 austenitic stainless steel. At first, three samples were rolled at the ambient temperature, the temperature of -20 ºC (dry ice and ethanol) and -196 ºC (liquid nitrogen). Then, the samples were annealed at 800 ºC in the time range of 1 to 15 minutes. In each step, the microhardness values of the samples were measur...
