The planeness and integrality of the flier - plate were ensured effectively by exerting restrictive pressure , controlling heating and cooling rate , lowering welding temperature or reducing welding time as much as possible , etc . theoretical model of creating quasi - isentropic compression via 93w - ofc - tc4 - a1 - mb2 system flier - plate with graded wave impedance was established , and numerical simulation of the impact process was then carried out 采取施加外部機械力、控制升降溫速率以及盡量降低焊接溫度或減少焊接時間(防止脆性金屬間化合物的過度增長)等措施,確保了焊接接頭的平整性和界面結構的完整性。建立起梯度飛片擊靶的理論模型,對93w - ofc - tc _ 4 - al - mb _ 2系波阻抗梯度飛片的擊靶過程進行了數值模擬計算。

By using diffusion welding method ( under certain welding parameters such as temperature , pressure , time and atmosphere , etc ) and employing rational structural control technique , a kind of 93w - ofc - tc4 - a1 - mb2 system flier - plate with good parallelism , planeness and high densification was prepared , which met the needs of initial design and the basic requirement of flier - plates 利用平面擴散焊接法(控制一定的溫度、壓力、時間、氣氛等條件) ,同時采取合理的結構控制方法,成功實現了93w - ofc - tc _ 4 - al - mb _ 2的整體連接,得到了平面性好、平行精度高、整體致密的波阻抗梯度飛片,滿足了設計結果和梯度飛片的基本結構要求。

In the present dissertation , five commercial metallic materials ? tungsten alloy ( 93w ) , oxygen free copper ( ofc ) , titanium alloy ( tc - t ) , pure aluminum ( al ) and magnesium alloy ( mb2 ) were chosen as the composite system of the flier - plate with graded wave impedance , and their acoustic and mechanical parameters were measured . the thickness of each material was controlled so that flier - plates with a parabolic or cubic wave impedance distribution were designed 依據實現準等熵壓縮和超高速發射對梯度飛片體系的理論要求,論文首先在一個較寬的波阻抗變化范圍內,確定鎢合金( 93w ) 、無氧銅( ofc ) 、鈦合金( tc _ 4 ) 、工業純鋁( al )和鎂合金( mb _ 2 )五種綜合性能良好的金屬和合金材料作為波阻抗梯度飛片的復合體系,并測量了材料的相關聲學和力學參量。

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于ofc與tc _ 4之間發生反應擴散,并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,由于熱膨脹系數的差異,擴散焊接后在不同焊件的接頭處存在殘余熱應力并由此引起接頭的形變。

At the same time , the thickness of target should also be in accord with the impact velocity . experiments of quasi - isentropic loading to 93 w alloys by 93w - ofc - tc4 - a1 - mbz system flier - plate with graded wave impedance were performed on light gas guns . the corrected visar - measured wave profiles were profiles with an initial velocity jump followed by a stepwise - rising front to the peak velocity amplitude , indicating that quasi - isentropic compression energy waves had been successfully generated 在輕氣炮上利用研制的93w - ofc一tc4 . ai一mbz系波阻抗梯度飛片實現了對93w合金(靶材料)的準等嫡壓縮,經修正后的測試波形都是由一個較弱的初始速度跳躍和一段呈階梯狀緩慢上升的波陣面前沿所組成的準等嫡壓縮波。
