    摘要:

    在真空熱熔W/CuCrZr復(fù)合板的基礎(chǔ)上進行了爆炸焊接，采用金相顯微鏡、掃描電鏡及能量色散X射線光譜對結(jié)合界面進行微觀形貌觀察，同時結(jié)合有限元計算探索了熱熔爆炸W/CuCrZr復(fù)合板界面的演化機制。結(jié)果表明：熱熔爆炸焊接W/CuCrZr 復(fù)合板的界面結(jié)合良好，具有3~8 μm交叉熔融區(qū)，但W側(cè)產(chǎn)生了裂紋。數(shù)值模擬再現(xiàn)了熱熔爆炸焊接過程中結(jié)合界面壓力、應(yīng)力、應(yīng)變及內(nèi)能變化規(guī)律，實驗產(chǎn)生裂紋的位置和數(shù)值模擬計算的高應(yīng)力位置吻合，熱熔爆炸焊接界面附近的高壓、高溫進一步促進了界面的結(jié)合。

    Abstract:

    Explosion welding was carried out on the basis of vacuum hot melt W/CuCrZr composite plate. Metallurgical microscope, scanning electron microscope and energy dispersive X-ray spectroscope were used to observe the microscopic morphology of the bonding interface. At the same time, combined with finite element calculations, the evolution mechanism of the interface of the hot melt explosion welded W/CuCrZr composite plate was explored. The results show that the interface bonding of the hot melt explosion welded W/CuCrZr composite plate is good and there is a cross-melting zone with 3–8 μm in thickness, but cracks are developed on the W side. The numerical simulation reproduces the changes of pressure, stress, strain and internal energy at the bonding interface in the process of hot melt explosion welding. The location of the crack generated in the experiment coincides with the high stress position calculated by numerical simulation. The high pressure and high temperature near the hot melt explosion welding interface further promote the bonding of the interface.
