摘 要: 研究了采用軋制復(fù)合方法生產(chǎn)不銹鋼-3003鋁合金蜂窩夾芯板的工藝。 結(jié)果表明： 經(jīng)過表面清理的面板和芯板， 在加熱至500~550℃后進(jìn)行軋制復(fù)合， 在變形率為25%以上時即可以實現(xiàn)牢固的初結(jié)合， 面板與芯板間的結(jié)合主要依靠“裂口機(jī)制”； 軋制過程中芯板上的圓孔出現(xiàn)了類似于墩粗的情況， 為使芯板上孔系能夠發(fā)揮作用， 軋制變形率應(yīng)當(dāng)控制在25%~40％之間； 經(jīng)過退火熱處理后， 夾芯板的抗拉強(qiáng)度、 彎曲強(qiáng)度和延伸率等力學(xué)性能均達(dá)到相關(guān)產(chǎn)品標(biāo)準(zhǔn)。

Abstract: The roll-bonding technology of stainless steel/3003 aluminum alloy honeycomb sandwich panel was studied. The results show that the skin and core plate whose surfaces are cleaned can realize excellent interface bonding when deformation rate exceeds 25% and temperature rangs from 500 to 550 ℃. The bonding way between both base metal is typically the split mechanism. And round holes of core plate appear bore-out-of-round during the course of roll-bonding. In order to make full use of the holes in the core plate, deformation rate of 25%-40% is demanded. The tensile strength, flexural strength and elongation of sandwich board all meet the correlative criteria after annealing heat treated.
Key words: stainless steel/3003 aluminum alloy; roll-bonding; honeycomb sandwich panel; split mechanism; deformation rate
