Determination of bond strength between the hard-faced (HF) layer and the base material (BM) of forging dies
(Faculty of Metallurgy, 2016)
This paper points out complex working conditions of forging dies, which are the most frequent causes of their damage, and proposes suitable hard-facing repair procedures. The shear strength between the hard-faced layer and ...
Effect of aging on mechanical properties of Al-8Si-8Fe-1.4v/SiCp composites
(Faculty of Metallurgy, 2016)
In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to Study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of ...
Selection of the optimal hard facing (HF) technology of damaged forging dies based on cooling time t8/5
(Faculty of Metallurgy, 2016)
In exploitation, the forging dies are exposed to heating up to very high temperatures, variable loads: compressive, impact and shear. In this paper, the reparatory hard facing of the damaged forging dies is considered. The ...
The influence of temperature on mechanical properties of the base material (BM) and welded joint (WJ) made of steel S690QL
(Faculty of Metallurgy, 2016)
This paper presents the analysis of the influence of temperature on mechanic properties of the base material and welded joints made of high strength steel. The joints were welded on S690QL high strength steel plates using ...
Effect of microstructure on tensile properties of austenite-ferrite welded joint
(Faculty of Metallurgy, 2015)
Complex microstructure of austenite-ferrite welded joint has been investigated, focused on its influence on Focal tensile properties. Tensile properties (yield strength and hardening coefficient) have been evaluated by ...
Cold weld cracking susceptibility of high strength low alloyed (hsla) steel nionikral 70
(Faculty of Metallurgy, 2014)
In view of the importance of high strength low alloy (HSLA) steels, particularly for critical applications such as offshore platforms, pipeline and pressure vessels, this paper reports on an investigation of how to weld ...
Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Faculty of Metallurgy, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
