U ovom radu teorijski je obrađena skupina cijepljenih ljevova te navedene njihove prednosti i nedostatci, područja primjene te utjecaj cjepiva na svojstva. U sklopu ovog zadatka bilo je potrebno obraditi nekoliko vrsti ljevova, a to su: meehanite lijev, modificirani sivi lijev, nodularni lijev, te vermikularni lijev. Uz to je još opisan opći postupak cijepljenja ljevova. Teorijskom analizom zadatka utvrđeno je da svaki od ljevova ima određene prednosti u odnosu na druge, no generalno se može utvrditi da nodularni lijev ima najbolja svojstva, dok se vermikularni lijev svrstava između nodularnog i modificiranog sivog lijeva. Meehanite lijev je posebna vrsta lijeva i smatra se poboljšanim sivim lijevom.

In this work, a group of grafted casts was theoretically treated and their advantages and disadvantages, their application area and the effect of the graft on their properties. Within this task it was necessary to process several types of cast iron, wich are: meehanite cast iron, modified gray cast iron, nodular cast iron, and vermicular cast iron. In addition, the general method of graft of the casts is described. Theoretical analysis of the task determined that each of the casts have certain advantages over the others but it can generally be determined that the nodular cast has the best properties while the vermicular cast is placed between nodular and modified gray cast iron. Meehanite cast is a special type of cast and considered to be an improved gray cast.
