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 ...
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 ...
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 ...
Reduction of production cycle time by optimising production and non-production components of time in the metalworking industry: a case study
(Southern African Inst Industrial Engineering, Pretoria, 2016)
The production cycle (PC) time, as a very important economic indicator of freezing current assets, involves the time needed to manufacture a unit or a series of units, from putting them into production until they are put ...
Fracture analysis of the pulley of a bucket wheel boom hoist system
(Polish Maintenance Soc, Lublin, 2016)
This paper presents the results of the pulley fracture analysis. Experimental investigations confirmed that the chemical composition and basic mechanical properties of the pulley material, except the impact energy at a ...
Best Practices of Biomass Energy Life Cycle Assessment and Possible Applications in Serbia
(Zagreb Univ, Fac Forestry, Zagreb, 2016)
This paper aims to highlight the advantages of using Life Cycle Assessment (or LCA) tool in energy sector for rational energy consumption, selection of green technologies and process optimization. Besides the definition ...
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 ...
