Abstract
U radu je analiziran utjecaj debljine stijenke na mehanička svojstva nodularnog lijeva. Rad se sastoji od dva dijela: teorijskog i eksperimentalnog. U teorijskom dijelu ukratko su objašnjena svojstva i primjena nodularnog lijeva. Također je prikazana i klasifikacija nodularnog lijeva, njegovo skrućivanje te utjecaj kemijskog sastava i mikrostrukture na mehanička svojstva lijeva. Osim elemenata koji utječu na svojstva i mikrostrukturu, prikazan je i utjecaj nodularnosti grafita te broja i veličine nodula na mehanička svojstva i mikrostrukturu. U eksperimentalnom dijelu ispitivan je utjecaj različite debljine stijenke na odljevke od nodularnog lijeva kvalitete EN GJS 400 – 15. Odlivene su Y – probe tri različite debljine i na tim ispitnim uzorcima su provedena metalografska i mehanička ispitivanja. Također je u sklopu rada ispitan i utjecaj različitog CE na mikrostrukturu i mehanička svojstva. Na temelju dobivenih rezultata utvrđeno je da svi odljevci pripadaju nodularnom lijevu EN GJS 400 – 15 te kako debljina stijenke utječe na mehanička svojstva.
Abstract (english)
This paper analyzes the influence of wall thickness on mechanical properties of ductile iron. It is composed of two parts: theoretical and experimental. In theoretical part properties and application are briefly discussed. There is a overview of ductile iron classification, its solidification and the influence of chemical composition and microstructure on mechanical properties. It is also shown the influence of graphite nodularity and the number and the size of nodules on mechanical properties and microstructure. In the experimental part influence of different wall thickness on ductile iron quality EN GJS 400 - 15 was tested. Y – probes with different wall thickness were casted and metallographic and mechanical testing were performed on this test samples. The influence of different CE on microstructure and mechanical properties was also tested. On the basis of the obtained results it was shown that the tested castings belong to the ductile iron EN GJS 400 – 15 and that the thickness affects on mechanical properties
