diffusion bonding 中文意思是什麼
diffusion bonding
解釋
擴散焊接-
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，為此人們試圖藉助于計算技術，對接頭行為進行數值模擬，以便找到共同規律，對擴散連接過程及質量進行預測與實時控制。 -

The interfacial microstructure and properties for ti ni in diffusion bonding process
擴散焊接界面的組織和性能 -
It was found that the interfacial bonding of 93w - ofc was both the joining action of ofc / w grains and that of ofc / ni - fe binders, whereas the joining of ofc to tc4 could be seen as the mutual intense diffusion effect between ofc / tc4 and as a result cu - ti intermetallic compounds were formed at the joint. the joining of tc4 - a1 and a1 - mb2 were also attributed to the result of diffusion between elements ti - al and al - mg respectively. on the other hand, residual thermal stress and stress - induced distortion were produced at the joint simultaneously due to the difference in thermal expansion coefficient of different welding " materials
研究表明， 93w與ofc的界面連接是ofc與93w中w晶粒的連接以及ofc與93w中ni - fe粘接劑的連接共同作用的結果； ofc與tc _ 4連接界面的形成是由於ofc與tc _ 4之間發生反應擴散，並由此在二者接頭處生成了cu - ti金屬間化合物的中間相； tc _ 4 - al的連接與al - mb _ 2的連接則分別是其基體元素ti 、 al之間和al 、 mg之間元素互擴散的結果，另外，由於熱膨脹系數的差異，擴散焊接后在不同焊件的接頭處存在殘余熱應力並由此引起接頭的形變。 -

It is found that, the sintering process of w - ni - fe - cu alloy was a typical liquid - phase process, which including particle rearrangement stage, dissolving - precipitation stage and solid - phase sintering stage. cu plays an important role in the particle rearrangement stage, while fe can promote the densification by forming ni - fe - w bonding - phase. ni can not only form the bonding - phase, but also enhance the diffusion between the w grains
研究表明， w - ni - fe - cu合金的液相燒結緻密化經歷了顆粒重排、溶解-析出和固相燒結等三個階段， cu僅在顆粒重排階段起主導作用； fe主要在溶解-析出階段通過形成ni - fe - w三元粘結相來促進w合金的燒結緻密； ni不僅參與形成ni - fe - w三元粘結相，並且在w晶界上通過與w的互擴散促進了固相w晶粒的粘合。
