چکیده
P. Mohyla, R. Cep, Faculty of Mechanical Engineering, VSB-Technical University of Ostrava, Czech Republic; Z. Kubon, Materials and Metallurgical Re search, Lt d., Cz ech Re p.; I . S amardzic, Jo sip Ju raj Strossmayer Un iversity of Osijek Mechanical Engineering Faculty i n Slavonski Brod Croatia This work is focused on testing and evaluation of creep properties of P92 base material (BM) and welded joints (WJ) as well. Up t o date results of cr eep rupture test of P92 base metal and w elds are presented in this ar ticle. Creep rupture strength (CRS) of WJ initially reaches values close to the BM, with longer times to fracture and especially at higher temperatures, creep strength of WJ decreases and the data is closer to the lower 40 % tolerance band.

Creep Deformation Measurement of 316H Stainless Steel Multi-pass Welded Joints using Digital Image Correlation
A high temperature measurement system for creep deformation based on the digital image correlation (DIC) technique is described. The new system is applied to study the behaviour of a multi-pass welded joint in a high temperature tensile test and a load controlled creep test at 545°C. Spatially resolved tensile properties and time dependent creep deformation properties across a thick section typ...

The most effective method to reduce CO2 gas emission from the steam power plant is to improve its performance by elevating the steam temperature to more than 700 ◦C. For this, it is necessary to develop applicable materials at high temperatures. Ni-based Alloy 617 and 12Cr steel are used in steam power plants, due to their remarkable mechanical properties, high corrosion resistance, and creep s...

In the present research, friction stir welding (FSW) process was used for butt joining of pure copper plate to 316L stainless steel plate. Mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (SEM). It was found that microstructure of the weld nugget (WN) has fine grains where...

متن کاملEffect of Welding Parameters in the Microstructure and Mechanical Properties of Friction-Welded Joints of 100Cr6 Steel
In this study, high-carbon, chromium alloy steel (100Cr6) having the initial spheroidized microstructure was welded using the rotary friction welding method. The effects of process parameters such as friction time and friction force were experimentally investigated. The friction welded joints were produced of two 100Cr6 steel rods. In order to examine the microstructure and mechanical properti...
