Analysis of the mixing of filler and base materials in arc-welded single-bead surface welds using an EDXS method
Borut Zorc, Matija Zorc, Aleš Nagode
Izvirni znanstveni članek
Oznake: covered electrodes;single-bead surface weld;segregation;EDXS analysis;admixing rate;
This article deals with an analysis of mixing and determines the admixing rate of a base S355 steel plate in single-bead surface welds by measuring the chemical composition using a planescan energy dispersive X-ray spectroscopy (EDXS) on metallographic cross-sections. The results show that obtaining ...

Matija Zorc, Aleš Nagode
Magistrsko delo
Oznake: podevtektoidna jekla;razogljičenje;oksidacija;žarjenje;dvofazno področje;
Raziskovalo se je razogljičenje svetlo brušene površine nelegiranih podevtektoidnih jekel C22, C45 in C60 pri različno dolgem žarjenju na temperaturah AC1 < Tž < AC3 v zračni atmosferi. Na teh temperaturah je mikrostruktura omenjenih jekel feritno-avstenitna. Raziskan je bil vpliv temperature in čas ...

Razvoj in karakterizacija železovih in manganovih zlitin za spajkanje nelegiranih in malolegiranih jekel
Matija Zorc, Aleš Nagode
Doktorska disertacija
Oznake: novi dodajni materiali na osnovi Fe-P in Mn-Fe-P;spajkanje;karakterizacija lastnosti;mikrostrukturne preiskave;strižni preizkus;
V sklopu raziskave smo razvili, karakterizirali in preizkusili nove dodajne materiale na osnovi Fe-P in Mn-Fe-P za spajkanje nelegiranih in malolegiranih jekel. Ti imajo relativno nizke temperature solidus in likvidus ter ozke talilne intervale in so poceni za izdelavo. Po razmisleku o optimalni ses ...

Determining the degree of admixing rate of the base material and the melting efficiency in single-bead surface welds using different methods, including new approaches
Matija Zorc, Aleš Nagode, Borut Kosec, Borut Zorc
Izvirni znanstveni članek
Oznake: arc welding;single-bead surface weld;admixing rate;melting efficiency;
The precise determination of the admixing rate of the base material for certain welding parameters is very important because of the possible negative consequences. As such, it is the basis for corrections in welding technology. In the article, experimental and theoretical determinations of the admix ...

Effect of the shape of styrene-acrylonitrile water-filter housings on the destructive pressure, crack-initiation, propagation conditions and fracture toughness of styrene-acrylonitrile
Borut Zorc, Matija Zorc, Borut Kosec, Aleš Nagode
Izvirni znanstveni članek
Oznake: styrene-acrylonitrile;geometrical shape;stress concentrator;destructive pressure;fracture toughness;
A destructive pressure test of styrene–acrylonitrile (SAN) water-filter housings showed the influence of the shape and specific details of the housings on their critical areas and their destructive pressure. The destructive pressure varies by as much as 37 bar due to different dominant stresses in t ...

Surface decarburization of the hypo-eutectoid carbon steel C45 during annealing in steady air at temperatures T > AC1
Matija Zorc, Aleš Nagode, Jaka Burja, Borut Kosec, Borut Zorc
Izvirni znanstveni članek
Oznake: carbon steel;annealing;air;oxidation;decarburization;
The non-alloyed hypo-eutectoid steel C45 was annealed in a steady air atmosphere at T > A$_{C1}$ using three temperature ranges and annealing times t$_a$ = 1/2 , 1 and 2 h. The oxidation and decarburization obeyed the parabolic law of growth with time and increased with higher temperatures and longe ...

Diplomsko delo
Oznake: upogibanje;razvita dolžina pločevine;K-faktor;eksperiment;numerične simulacije;
Upogibanje je ena najpogostejših operacij preoblikovanja pločevine v proizvodni industriji. V diplomski nalogi je natančneje obravnavana proizvodna industrija klimatskih naprav. Gre za plastično deformiranje pločevine okoli osi, pri čemer se spremeni njena oblika. V pločevini med upogibanjem nastane ...

In this work, TiO$_2$ was incorporated into the surface of cotton fabrics by an in situ sol–gel/hydrothermal approach. Dimethyloctadecyl [3-(trimethoxysilyl) propyl] ammonium chloride (SiQAC) was added as a bio-barrier Si precursor to enhance the synergistic effect/binding of TiO$_2$ to the surface ...
