A Study on the Fatigue Crack Growth Characteristic of the Electron Beam Welds of D6AC Ni-Cr-Mo-V steel
碩士 === 國立中央大學 === 機械工程研究所 === 83 === Interlocked本研究目的,在利用不同銲接道次(即多重銲道)及改變銲接 參數對 D6AC Ni-Cr-Mo-V鋼之銲道凝固金相組織及強度、疲勞裂縫成長速 率影響 ,實驗採用電子束銲接;改變電流、銲速、電壓均採固定,區分為 1.擺弧銲一、二、三道。 2.不擺弧銲一、二、三道。銲道經X-ray檢驗、 金相分析、微硬度、拉伸機械性質及疲勞裂縫成長等測試,並以掃描式電 子顯微...
