Abstract
V podjetju uporabljamo titanove zlitine z legirnimi elementi za povečevanje oksidacijske odpornosti pri povišanih temperaturah, ki znižujejo preoblikovalnost. V okviru magistrske naloge smo se osredotočili na proučevanje preoblikovalnih lastnosti dveh najpogosteje uporabljenih titanovih zlitin. Obravnavali smo preoblikovalne lastnosti v treh različnih smereh glede na valjanje pločevine. Stanje pločevine je popisano z merjenjem debelin na specifičnih lokalnih mestih, obravnavana je relaksacija globoko vlečenih izdelkov na osnovi optičnih 3D meritev. Predstavljena je metalografska analiza uporabljenih titanovih zlitin z izmerami trdot. Na osnovi predstavljene raziskave preoblikovalnih lastnosti pločevine je izbrana primerna titanova zlitina in ustrezna smer izreza platine za naknadni proces globokega vleka.

Title:Analysis of the suitability of titanium alloys for cold forming
Abstract:
The company uses titanium alloys with alloying elements to increase oxidation resistance at elevated temperature, which reduces its formability. In master’s thesis we focused on the study of the formability properties of two most commonly used titanium alloys. We focused on the formability properties in three different directions according to sheet metal rolling. The research of the sheet metal included thickness measurement in certain places, and the relaxation of deep-drawn products based on optical 3D measurement. Also a metallographic analysis of titanium alloys with hardness measurement is presented. According to our presented research of the sheet metal forming properties, a suitable titanium alloy and the appropriate blank cutting direction are selected for the deep draying process.

Keywords:titanium alloys, heat treatment of titanium, ultrasonic thickness measurement, penetrant testing, microstructure, 3D scanning
