A Study of the Microstructure and Mechanical Properties of Continuously Cast Iron Products

The horizontal continuous casting has a lot of advantages in comparison with traditional casting methods. But it has a few disadvantages and unsolved problems. The objective of this research was the experimental investigation of the effect of chemical composition of cast iron and the casting conditions on the microstructure and properties of continuously cast ingots. As a result, tensile strength, Brinell hardness, and pearlite content increased with increasing Cr, Cu, and Sb additions and decreasing carbon equivalent. As for microstructure of graphite, higher silicon to carbon ratio and lower solidification rate decreased a zone of interdendritic graphite. Nomograph of continuously cast iron structure was made

Effect of Melting Techniques on Ductile Iron castings Properties

The study was designed to investigate the effects of the charge, melting conditions, nodularizing and inoculation on the ductile iron castings properties. Results showed that the temperature and holding time of the melt in an induction furnace and the intensity of spheroidizing effect on the carbon and residual magnesium contents in the ductile iron castings. The same grade of ductile iron may be obtained using different chemical compositions. The castings of ductile iron will be ferritic as-cast only when large amount of pig iron in the charge and in addition some-steps inoculating treatment are used

Raspored zaostalih naprezanja u podpovršinskim slojevima ugljičnog čelika pri ispitivanju na vlak

The task of our research was to investigate the character of distribution, magnitude and sign of residual stresses in cross-section of a sample in micro-yield, yield and strain hardening stages of monotonic deformation. The analysis of the obtained experimental data shows the peculiarity of micro-plastic flow near a free surface of a solid body and its rather significant influence on the general character and kinetics of macroscopic deformation of metals.Zadatak je istraživanja proučavanje karaktera rasporeda, veličine i oznake zaostalih naprezanja po presjeku uzorka pri statičkoj deformaciji (vlačno naprezanje) u stadiju mikro granice razvlačenja, granice razvlačenja i deformacijskog očvršćavanja. Analize dobivenih eksperimentalnih rezultata svjedoče o karakteru mikroplastičnog razvlačenja u podpovršini krutog tijela i njegovom bitnom utjecaju na opći karakter i kinetiku mikroskopske deformacije metala
