Abstract
Kovanje je jedan od najstarijih zanata poznatih čovjeku. Zahvaljujući njegovom razvoju razvijen je značajan broj grana gospodarstva, ali se napredovalo i na području ratovanja i osvajanja teritorija. Prema tome, predmet istraživanja ovog rada je utjecaj brzine deformiranja na krivulje tečenja kod procesa sabijanja u hladnom stanju. Uz pomoć analizirane literature te primjenom stečenog znanja opisan je proces i vrste kovanja, zajedno sa strojevima pomoću kojih se kovanje izvodi te osnovni pojmovi koji se vezuju uz krivulju tečenja kao svojstvo materijala koje se ostvaruje u procesu deformacije materijala. Krivulja tečenja povezuje naprezanje sa stupnjem deformacije materijala. Praktični dio rada prikazuje eksperiment koji je uključivao valjčiće koji su sabijani različitim brzinama uz pomoć gravitacijskog bata te hidraulične preše. Ostvareni rezultati prikazani su analizirani matematičkim izračunima te prikazani grafički, a temeljem istih doneseni su i određeni zaključci.
Abstract (english)
Forging is one of the oldest crafts known to man. Thanks to its development, a significant number of branches of the economy were developed, but progress was also made in the field of warfare and conquest of territory. Therefore, the subject of research in this paper is the influence of the deformation rate on the flow curves during the cold upsetting process. With the help of the analyzed literature and the application of the acquired knowledge, the process and types of forging are described, along with the machines that are used to forge, and the basic concepts related to the flow curve in the deformation process. The practical part of the work shows an experiment that included billets that were compressed at different deformation rates with the help of a gravity drop hammer and a hydraulic press. The obtained results are analyzed with mathematical calculations and presented graphically, and certain conclusions are drawn based on them.
