異溫軋制制備鈦/鋁復(fù)合板的變形協(xié)調(diào)性與復(fù)合性能Deformation coordination compatibility and bonding properties of Ti / Al composite plates prepared by different temperature rolling

采取只加熱鈦層的方法實(shí)現(xiàn)協(xié)調(diào)變形軋制制備鈦/鋁復(fù)合板，通過剪切實(shí)驗(yàn)、金相顯微鏡、掃描電子顯微鏡，研究壓下率、鈦層加熱溫度對(duì)鈦/鋁復(fù)合板的厚比分配、剪切強(qiáng)度和界面的影響。結(jié)果表明：隨著鈦層溫度的升高和總軋制壓下率的增大，鈦鋁復(fù)合板的鈦層和鋁層變形率差值逐漸減?。划?dāng)溫度為800 ℃，軋制壓下率為50%時(shí)，鋁層和鈦層的變形率分別達(dá)到了51.4%和 48.6%，鈦鋁復(fù)合板變形趨于協(xié)調(diào)。鈦與鋁的結(jié)合界面剪切強(qiáng)度達(dá)到107.5 MPa，基本接近鋁基體的剪切強(qiáng)度。加熱過程中鈦板表面會(huì)產(chǎn)生氧化層，但是在較大軋制壓下率下，鈦的氧化層會(huì)撕裂，金屬鋁擠入裂縫與新鮮鈦金屬接觸，在強(qiáng)大壓力和高溫作用下，鈦、鋁元素相互擴(kuò)散從而達(dá)到牢固的冶金結(jié)合。

The Ti/Al composite plate was prepared by the method of only heating titanium layer. The effects of the rolling reduction and Ti layer heating temperature on the shear strength, interface and distribution of thickness ratios of Ti/Al clad plates were investigated by shear experiments, metallographic microscopy and scanning electron microscopy. The results show that with the increase of the temperature of the titanium layer and the total rolling reduction, the difference between the titanium layer and the aluminum layer deformation of the Ti/Al composite plate decreases gradually. When the temperature is 800 ℃ and the reduction is 50%, the reduction of aluminum layer and titanium layer reaches 51.4% and 48.6%, respectively. And the deformation of titanium/aluminum composite plate tends to become coordinated. The interfacial shear strength of titanium and aluminum reaches 107.5 MPa, which is close to the shear strength of aluminum matrix. During the heating process, an oxide layer is produced on the surface of the titanium plates. However, the oxide layer is completely broken with a large rolling reduction, and then, aluminum metal extruded into the cracks and made contact with fresh titanium metal. Under the action of high pressure and high temperature, Ti and Al atoms mutually diffuse so that the Ti/Al clad plates achieved a strong metallurgical bond.
