AbstractThe present study emphasizes on joints two industrially important materials AISI 304 with AISI 1021steels, produced by friction welding have been investigated. Samples were welded under different axial pressures ranging from 75MPa to 135MPa, at constant speed of 920rpm. The tensile strength, torsional strength, impact strength and micro hardness values of the weldments were determined and evaluated. Simultaneously the fractrography of the tensile tested specimens were carried out, so as to understand the failure analysis. It was observed that improved mechanical properties were noticed at higher axial pressures. Ductile failures of weldments were also observed at 120MPa and 135MPa axial pressures during fractography analysis.

Boundary Embrittlement

Two types of steels used for production of heavy forgings were selected for the experimental evaluation of the effect of long time dwell at elevated temperatures and cooling during heat treatment on their mechanical properties in order avoid the possibility of grain boundary embrittlement. Samples from evaluated steels 26NiCrMoV14-5 and 22CrNiMoWV8-8 were austenitized for 2 hours at temperature of 1200°C and oil quenched. Subsequently the annealing at temperatures (200 - 700)°C for 1 hour and 100 hours was applied. Selected mechanical properties, especially hardness and impact energy, were monitored. It was found that for steels 26NiCrMoV14‑5 and 22CrMoNiWV8-8 exist the temperature intervals (300 - 400)°C and (500 ‑ 600)°C respectively with the possible potential for toughness decreasing.

Tension Members

Recent commercial activities in the deeper regions of seas and oceans have placed increasing demands for higher strength-to-weight ratio tension members with certain improved mechanical properties. Activities such as heavy lifting in subsea regions can impose extreme dynamic loading conditions as well as other environmental factors on ropes used as tension members for those applications. In this paper, some recently developed synthetic fiber and hybrid tension member technologies that may provide solutions for some of these challenging needs are presented. A proposal for a hybrid rope concept is presented which is envisioned to provide for more effective cooling of the rope in high cycle bending applications such as active heave compensated winches. A proposal for numerical modeling and experimental evaluation of heat transfer rates in such a hybrid rope is briefly presented. A short overview of the current ASME B30 standard volumes for land-based crane rope usage and inspection, as well as ISO 4309 and the API 2D standards will also be presented.

Concrete Properties

Currently there are two bridges older than 120 years under reconstruction in Slovakia. One of them is the Old Bridge in Bratislava, which has been built in 1891 and has a steel superstructure supported by concrete piers. The other one is the Monier Arch Bridge in Krásno nad Kysucou, which has been built in 1892. Since only limited information about the properties of such an old concrete is available, it was almost impossible for the designer to verify the load bearing capacity of these bridges and to design their reconstruction efficiently. To verify the properties of these concretes drill cores were made on both bridges, some of them being more than 20 meters long [17]. After that the measured concrete properties were used to confirm or modify the reconstruction method proposed in the preliminary design. Our paper deals with some mechanical properties measured on these more than 120 years old concretes.
