The influence of buffer layer on the properties of surface welded joint of high-carbon steel
(Institute of Metals and Technology, 2011)
Surface welding with buffer layer is often in use because of its well-known properties of plasticity, or ability to slow crack growth initiated. However, in modern surface welding technologies, buffer layer is rarely used. ...
Computer-aided modeling of the rubber-pad forming process
(Institute of Metals and Technology, 2012)
The conventional way to develop press-formed metallic components requires a burdensome trial-and-error process for setting-up the technology, whose success depends largely on the operator's skill and experience. The finite ...
Distortion of the substructure of a 20-ft shipping container exposed to zinc hot-dip galvanizing
(Institute of Metals and Technology, 2013)
The main goal of this study was to build a model for a numerical simulation of hot-dip galvanizing of a 20-ft ISO shipping container. For that purpose, the basic transient thermo-mechanical problem of a steel structure ...
Selection of the most appropriate welding technology for hardfacing of bucket teeth
(Institute of Metals Technology, 2015)
A possibility of extending the service life of the working parts of construction machinery with particular attention to hardfacing of loader bucket teeth was investigated. In the first part of this paper the tribological ...
Superplastic deformation of an x7093 al alloy
(Institute of Metals Technology, 2014)
We have investigated the superplastic deformation mechanism of a powder-metallurgy, high-zinc X7093 Al alloy. The objective was to examine the rate-controlling mechanisms that govern its superplastic deformation. The ...
Friction-stir welding of high-strength aluminium alloys and a numerical simulation of the plunge stage
(Institute of Metals and Technology, 2012)
This paper defines a set of welding parameters for the Friction-Stir Welding (FSW) of two forged panels of the alloy EN AW 7049A in a T652 temper and discusses the plunge stage of FSW using numerical modeling. This ...
Lacunarity properties of nanophotonic materials based on poly(methyl methacrylate) for contact lenses
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2017)
The aim was to develop new materials that would, after appropriate machining processes, improve the surface roughness and wettability of contact lenses. The samples used in this investigation were standard rigid gas-permeable ...
Theoretical and experimental estimation of the working life of machine parts hard faced with austenite-manganese electrodes
(Institute of Metals and Technology, 2012)
We have investigated the possibility of repairing damaged machine parts by hard facing with austenite-manganese steel electrodes. The subject is a Fe-C-Mn alloy with a microstructure of soft austenite which, after cold ...
Experimental analysis of dental-implant load transfer in polymethyl-methacrylate blocks
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2019)
Dental-implant overload can cause bone resorption. Load-transfer characteristics of dental implants are affected by their macro-design parameters. The goal of this study was to experimentally analyse the load-transfer ...
Deformation mechanisms in ti3al-nb alloy at elevated temperatures
(Institute of Metals and Technology, 2010)
Ti3Al-11Nb-1V (x/%) was made in a vacuum arc furnace. Hot-rolling was conducted at 1050 degrees C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 degrees C and strain rates of 10(-6) ...
