文摘:簡述了目前國內外在擴散焊檢測方面研究發(fā)展的概況，著重介紹了應用比較普遍的超聲波檢測法，并就擴散焊接頭質量檢測的應用前景等發(fā)表了作者的看法。
The diffusion welding behavior of single - crystalline cu to single - crystalline - aio with a nb film interlayer and the joint microstructure properties were studied by tem , sem / eds analyses and four - point bend testing . the nb film interlayer deposited by electron beam evaporation on the ceramic side prior to diffusion welding was found to be olycrytalline and fiber - textured after diffusion bonding , with the close - packed plane ( 110 ) being parallel to the ( 0001 ) basal plane of - aio
擴散連接技術是一門邊緣科學，涉及材料、擴散、相變、界面反應、接頭應力應變等各種行為，工藝參數多，雖然已經進行了大量的試驗研究，但卻對各種材料的連接機理尚未有明確的認識，為此人們試圖借助于計算技術，對接頭行為進行數值模擬，以便找到共同規(guī)律，對擴散連接過程及質量進行預測與實時控制。
