(1)漢譯英: 焊接電流為50A的接頭焊縫區(qū)的X射線衍射圖譜如圖6所示。從圖可以看出,焊縫區(qū)存在α-Mg和β-Mg17Al12兩種衍射峰,其中后者衍射峰較弱,僅出現(xiàn)一個衍射峰,這表明AZ31B鎂合金焊縫由大量的α-Mg和少量的Mg17Al12 組成。根據(jù)Mg-Al二元相圖[9],平衡凝固過程中,當鋁含量大于1.5%時就會結晶出化合物相Mg17Al12。在TIG焊過程中,由于熔池金屬中的Mg元素蒸發(fā)燒損, Al元素含量相對增大,同時焊縫凝固速度快,因此焊縫中會存在比母材中更多的Mg17Al12。 (2)The experiment was carried out using TDI-500 AC-DC pulse welding machine, its maximum output current is 500A. The welding technique of one-side welding with both-sides molding was used, and play-movement is 0.1mm.Mechanical properties were determined by CMT5105 standard tensile tests on small-scale specimens, which produced by MTS (China) Co., Ltd.請問這段英語中表述對嗎?有沒有語法時態(tài)錯誤?麻煩了,謝謝 |
