Die Architektur Iwan Leonidows und die Komposition der Landschaft der russischen Stadt
No full textL'architettura di Ivan Leonidov, spesso considerata dalla critica come visionaria e proiettata solo sul futuro, è qui riconsiderata rispetto ad una serie di "punti" che confermano invece un approccio realistico rispetto ai problemi insediativi e ai processi di trasformazione della città sovietica negli anni '20 e '30. Il testo è una rielaborazione sintetica del testo pubblicato nel catalogo italiano della mostra "Una città possibile. Architetture di Ivan Leonidov 1927-1934"

Odporność grafityzowanej stali na zużycie ścierne
No full textHeat-treated graphitized steels with different carbon, silicon and copper contents have been the object of study. The influence of the composition on the structure and wear resistance (weight loss of the specimen) of graphitized steels (after hardening and tempering) under the conditions of metal to metal dry sliding friction with the use of Amsler-type friction machines, has been investigated in this work. Research results have shown that the main factors affecting wear resistance of graphitized steels have been not only their metal base hardness, but the quantity, shape and distribution of graphite inclusions uniformity in the structure of such steels as well. A regression dependence of the quantity of specimen’s weight loss on carbon, silicon and copper content has been obtained in the work. The highest wear resistance was pertained by the steel having the following content: 1.60. . . 1.70%C; 2.20. . . 2.30%Si; 0.80. . . 0.90%Cu; 0.60. . . 0.70%Mn; 0.15. . . 0.18%Cr; 0.22. . . 0.25%Al; up to 0.015%S and 0.024%P.Przedmiotem badań była grafityzowana stal (po obróbce cieplnej) o zróżnicowanej zawartości węgla, krzemu oraz miedzi. W pracy przedstawiono wyniki badań wpływu składu chemicznego grafityzowanej stali, po hartowaniu i odpuszczaniu, na jej strukturę i zużycie ścierne (zmniejszenie masy próbki) w warunkach suchego tarcia ”metal-metal” na maszynie typu Amslera. Wyniki badań świadczą o tym, że odporność na zużycie ścierne zależy nie tylko od twardości osnowy metalowej, lecz także od ilości, kształtu i jednorodności wydzieleń grafitu oraz rozkładu przestrzennego wtrąceń w strukturze stali tego typu. Otrzymano zależności regresyjne wartości ubytku masy próbek w funkcji zawartości węgla, krzemu i miedzi. Największą odpornością na zużycie ścierne wyróżniają się stale o następującym składzie chemicznym: 1,60. . .1,70% C, 2,20. . . 2,30% Si, 0,80. . . 0,90% Cu, 0,60. . . 0,70% Mn, 0,15 . .. 0,18% Cr, 0,22. . . 0,25% Al, do 0,015% S i 0,024% P

INFLUENCE OF THE CAST IRON’S CHEMICAL COMPOSITION ON THE CONTENT OF CR IN THE BASE AFTER NORMALIZATION FROM 1050 C
No full textThe dependences of the influence of the chemical composition of cast iron in the Fe-Cr-Mn-Ni system on the chromium cotent in the metal base (Cr1050о) and carbides (Cr1050Cr) after normalization from 1050 °C with aging for 4.5 hours were established. During the heat treatment of the castings, a redistribution of the elements between the phases of the cast iron occurred. The maximum chromium concentration in the base after normalization was 19.7% at 1.09% C, 3.1% Mn, 25.5% Cr and 0.19% Ni, and the minimum 2.4% at 3.91% C, 0.6% Mn, 11.43% Cr and 0.19% Ni. The maximum amount of chromium in carbides 78.4% was observed in cast iron containing 1.09% C, 5.4% Mn, 3.01% Ni and 25.57% Cr, and the minimum 43.5% at 3.59% C, 5.4% Mn, 3.01% N and11.43% Cr. The obtained dependencies allow predicting the chromium content in the metallic base and can be used during the elaboration of new compositions for wear-resistant cast iron, as well as at choice of heat treatment regimes
INFLUENCE OF THE CAST IRON’S CHEMICAL COMPOSITION ON THE INTERPHASE DISTRIBUTION OF MN
No full textPurpose. This paper focuses on obtaining the dependencies of the manganese content in the metallic base (Mno) and its interphase distribution coefficient (KPMn) on the cast iron’s chemical composition in the system Fe–C–Cr – Ni –Mn. Methodology. The cast irons containing 1.09…3.91% С, 0.6…5.4 % Mn, 11.43…25.57 % Crand 0.19…3.01 % Ni have been studied. The active experiment design techniques were applied to build a mathematical model of manganese distribution. Cast iron was smelted in the induction furnace with the capacity of 60 kg, with basic lining.Findings.Manganese, being a carbide-forming element, distributed between carbides and the metallic base. With the use of the mathematical statistics methods, regression dependencies of the manganese concentration in the base and its interphase distribution coefficient on the С, Mn, Cr and Ni content in the cast iron were established. The manganese concentration in the base varied from 0.37 % at 1.09 % С, 0.6 % Mn, 11.43 % Cr and 3.01 % Ni to 5.79 % at1.09% С, 5.4 % Mn, 25.57 % Cr and 0.19 % Ni. The minimum value of the interphase distribution coefficient was 0.16 in the cast iron containing 1.09 % С, 0.6 % Mn, 25.57 % Cr and 3.01 % Ni. When the КРMn coefficient values were lower than 1, manganese concentrated predominantly in the metallic base. The maximum value of the КРMn coefficient was 2.48 at 3.91 % С, 0.6 % Mn, 11.43 % Cr and 0.19 % Ni. The manganese distribution pattern was determined by the carbides’ quantity and chromium and carbon ratio that determined the carbide type. The carbides’ composition was formed as a result of carbide-forming elements contention. Originality. Regression dependencies of the manganese content in the base and its interphase distribution coefficient on the cast iron’s chemical composition in the system Fe–C–Cr – Ni –Mn have been obtained. The dependency of the manganese distribution on the carbide forming processes has been established. Practical value. The obtained dependencies allow predicting the manganese content in the metallic base and may be used during the elaboration of the new wear resistant cast irons compositions
