The goal of this paper is to test the effect of odification process of liquid steel with 4-7% silicon content, in the course of pouring out from steel-smelting furnace into ladlet, on macrostructure. The research settled ...

This paper presents the results for modeling of the rolling process based at the deformable continuous medium mechanics, the theory of field lines. The rolling of the profiles and plates may be evaluated as the plane ...

The tribocorrosion properties of ZrO2 – nickel microstrucured composite coatings have been studied in the following conditions: -Solution: 0.5M K2SO4 -Tribo corrosimeter: pin on disc connected with electrochemical ...

The structural optimizing of used mechanisms in the machines construction and metallurgy through the further liberty degrees creation is essential projection problem, as it enters the closing mechanisms case with sliding ...

Determination of mercury in incidentally polluted waters, presented in CALIST Program, was carried out using tiobis-β-naphthol as a reagent. The method proposed for mercury determination, named “collecting gravimetry in ...

In this paper are presented some art pieces, used in orthodox religion for artificial general lighting. These pieces, realized at SC RANCON SRL Jassy, present a special importance, because they join harmoniously the ...

This paper presents comparative results concerning the chemical composition and mineralogical distribution of the main compounds from the structure of the archaeological patina of ancient bronze coins, which were determined ...

Stainless austenite steel types have a good resistance to corrosion in different natural, industrial environments but their hardness and mechanical resistance are low enough. In order to assure an increased resistance ...

The paper presents a study made at the annealing furnaces for homogenization of cast pieces regarding the replacement of marsh gas with blast furnace gas, in a proportion of 100%. In this way an important economy of marsh ...

Pursuant international standards such of the European ones, the nondestructive examinations have to be worked out by the most possible accuracy and repeatability, that allow the difference making between the admitted ...
