  • 本研究以兩種材料-不銹鋼SUS304與鈦合金Ti-6Al-4V進行混合物理與數值模擬,而再驗證比對模擬結果,確認數值模型之真實性與適用性後,便藉由此數值模型評估鈦合金Ti-6Al-4V製程參數對溫鍛製程之影響。
     為了能夠針對難以鍛造又缺乏實際生產經驗的材料鈦合金Ti-6Al-4V進行溫鍛製程規劃與評估,本研究採用混合物理模擬與有限元素數值模擬兩種模擬的新模擬架構。此模擬方式是先利用業界常用的不銹鋼SUS304進行物理模擬的實驗,確立整體溫鍛製程的實驗架構,並了解實際製程參數的影響,再建立不銹鋼SUS304溫鍛製程之有限元素數值模型,以其實驗與模擬結果進行比對驗證,確立有限元素數值模型在此溫鍛製程下的真實性,而後將有限元素數值模型應用於目標材料鈦合金Ti-6Al-4V上,再以物理模擬實驗對有限元素數值模擬做驗證,確認此鈦合金溫鍛製程之有限元素數值模型及參數值與真實情況相符合,最後可藉由此模型進行不同製程參數的製程模擬預測,而得到鈦合金Ti-6Al-4V溫鍛的製程設計評估結果。

    To evaluate the effects of process parameters in Ti-6Al-4V warm forging process, this thesis proposed a new process development model. The model consists of physical and numerical simulation of stainless steel SUS304 and titanium alloy Ti-6Al-4V. With mutual verification of these two simulations, the simulation results can be verified and the applicability of the numerical simulation can also be assured.
    First step of the new analysis model is establishing the physical simulation experiment of SUS304. With this step, the warm forging process can be set up and the effects of process parameters can be clarified. Then the numerical simulation model of SUS304 can be established precisely because the details of the warm forging process are verified in the physical simulation experiment. By comparing the results of physical and numerical simulation, the result of the numerical simulation of warm forging process can be confirmed. Therefore, the numerical simulation of SUS304 can be changed into the numerical simulation of Ti-6Al-4V. Not only the numerical simulations were performed but also the physical simulation experiment of Ti-6Al-4V. Then by comparing the results of physical and numerical simulation of Ti-6Al-4V, the accuracy of numerical simulation of Ti-6Al-4V can be confirmed. With the verified numerical simulation model of Ti-6Al-4V, the effects of different process parameters can be predicted and the process parameters of Ti-6Al-4V warm forging process can be obtained finally.
