20.500.12556/RUL-105425 Oblikovanje in izdelava noža iz damaščanskega jekla Modelling and production of Damascus steel knife Namen diplomskega dela je bil izdelati nož s postopkom damasciranja. Poudarek je bil na oblikovanju noža tako z vidika originalnosti oblike kot tudi vzorca rezila. Poleg dizajna nas je zanimala kvaliteta oziroma trdnost zvarov med posameznimi plastmi, ki so nastale pri postopku kovaškega varjenja. Teoretični del zajema predstavitev dveh različnih postopkov damasciranja, predstavitev jekel CK75 in 90MnCrV8, opis kovanja in opis uporabljenih metod v eksperimentalnem delu. V poglavju rezultatov in diskusije so združeni vsi izsledki analiz in meritev ter njihova interpretacija. Ugotovili smo, da je material iz katerega smo izdelali nož podvržen krhkemu lomu. Posamezne plasti jekel so se med kovanjem različno deformirali pri čemer so boljši kovaški vari na spojih med različnima jekloma kot pa na spojih med posameznimi lamelami istega jekla. The purpose of the thesis is to forge a Damascus steel knife. The emphasis was on knife design both in terms of originality of the shape and the sample of the blade. In addition to the design, we were interested in the quality and strenght of welds between the individual layers created by the pattern-welding process. The theoretical part consists of the presentation of two different processes of Damascus steel forging, the description of the CK75 and 90MnCrV8 steel, a description of the forging process and a description of the methods used in the experimental work. Under the results and discussion section are combined, all the results of analysis and measurements and their interpretation. We found that the material from which we made the knife is subject to a fragile fracture. The individual layers of steel were differently deformed during forging, with better welds on the joints between the different steel than on the joints between the individual lamellas of the same steel.
