소성 가공 해석을 통한 티타늄 합금 볼트 열간 단조 공정 분석

초록

Titanium alloy has been in the spotlight as a core material in high-tech industries that require high strength andlight weight because it has excellent strength and corrosion resistance and strength is higher than that of steel. Therefore,in various industries, existing steel products are intended to be replaced with titanium alloys. Titanium alloys can causecutting tool breakage during cutting, and heat generated during cutting does not dissipate, accumulates in tools andworkpieces, resulting in large wear and tear on thin workpieces. In addition, since titanium alloy is a metal with highchemical activity, the wear of the tool becomes more severe when the cutting speed is high, so machining of titaniumbolt through cutting is very disadvantageous in terms of productivity. Therefore, the production of bolts using titaniumalloys is being produced through a forging process to improve productivity and product quality. In this paper, hot forgingmolding analysis was performed on bolts used for fastening automobile parts using Ti-6Al-4V alloy, which is the mostcommonly used titanium alloy
