摘要:
采用“热旋锻-拉拔”方法制备了直径为Φ65 μm、包覆铜层厚度较均匀、表面质量高和界面结合质量良好的铜包铝复合微丝,研究了合理热旋制度、热旋复合成形铜包铝线材的组织和界面结合状态以及中间退火和拉拔对线材组织与性能的影响.结果表明:合理的旋锻制度为旋锻温度350°C,单道次变形量40%,旋锻后形成了动态再结晶组织和厚度为0.7 μm的界面扩散层.复合线材的合理退火工艺参数为350°C/30 min(退火温度350°C、退火时间30 min),该条件下退火后线材延伸率达到最高值35.7%,界面扩散层厚度约为2.1μm,退火后铜层和铝芯发生再结晶,组织内部形成等轴晶组织.当退火温度超过350°C时,铜层和铝芯晶粒长大,界面扩散层厚度增加,从而导致线材的延伸率下降.将单道次变形量控制在15%~20%,经过粗拉,制备了Φ0.96 mm的丝材;粗拉后不进行退火处理,将单道次变形量控制在8%~15%,经过细拉,制备了表面光洁、直径为Φ65μm的复合微丝.在拉拔过程中,铜层和铝芯均出现(111)丝织构.

摘要:
研究了充芯连铸铜包铝复合材料的界面层微观组织及其形成机理,结果表明,在连铸过程中,铜与铝界面结合为非等温固-液反应扩散过程控制,铜铝界面层厚度与纯铜溶解的厚度成正比.可采用叠加原理求得铜的溶解厚度,其计算过程如下:首先获得铜包铝复合材料界面温度-时间冷却曲线;冷却曲线被分成若干时间间隔,在每个时间间隔内,铜的溶解可看成是等温过程;将每个温度间隔铜溶解的厚度累加起来得到总的溶解厚度.计算结果和实验结果相吻合,可为实验过程提供指导.%The microstructures and formation mechanism of the interface layer of copper cladding aluminum (CCA) composites fabricated by core-filling continuous casting (CCFC) was studied.The results show that during the continuous casting process,the Cu/Al interface bonding is controlled by the non-isothermal reactive diffusion and the interface layer thickness is proportional to the dissolved thickness of Cu on the basis of mass conservation.The superposition principle method was used to calculate the dissolved thickness of pure Cu and the calculation process was summarized as follows:interfacial temperature-time cooling curve of CCA composite was obtained firstly;the cooling curve was divided into intervals,each of which was treated as isothermal process;the thickness of dissolved pure Cu was obtained by counting the thickness of each interval.The calculation results were in good agreement with the experimental results,which could be provided as the reference to guide experiments.

摘要:
以100 mm×100 mm大断面铜包铝棒坯为对象,建立棒坯连铸复合成形的数值模型,确定模型的边界条件,并通过设计的实验验证数值模型边界条件的准确性.基于验证的边界条件,采用ProCast软件对铜包铝棒坯立式连铸复合成形过程的稳态温度场进行数值模拟,得到了各工艺参数对连铸过程的影响规律,给出了工艺参数的调控策略和合理范围.结果表明,制备100 mm×100 mm大断面铜包铝铸坯的合理工艺参数范围为:在保持铜液温度1250°C的条件下,铝液铸造温度为760~790°C;一冷水流量为1600~2000 L/h;二冷水流量为900~1100 L/h;二冷水距结晶器石墨套出口距离为20 mm;拉坯速度为80~100 mm/min.%Taking the copper clad aluminum composite billet with a large section size of 100 mm×100 mm as an object, a numerical simulation of continuous core-filling casting was established. The boundary conditions of the numerical model were determined, and its accuracy was verified by convenient experiment. Based on the verified boundary conditions,the steady-state temperature field of large section copper clad aluminum during the casting was numerically simulated by ProCast software. The effect of each processing parameter on the casting processing is obtained and the controlling method and proper range of the processing parameters are given. The results show that the reasonable processing parameters in preparing copper clad aluminum in 100 mm×100 mm cross section are as follows: under the condition of the casting temperature of copper of 1250°C, the casting temperature of aluminum is 760?790°C, the flux of the first cooling water is 1600?2000 L/h, the flux of the second cooling water is 900?1100 L/h, the distance from the second cooling water to the exit of graphite crystallizer is 20 mm, and the withdrawing speed is 80?100 mm/min.

摘要:
The Cu−Al composite casts were prepared by the method of pouring molten aluminum. The solidification process and the microstructure of the transition layer were investigated during the recombination process of the liquid Al and the solid Cu. The results reveal that the microstructure of the transition layer in the Cu−Al composite cast consists of α(Al)+α(Al)−CuAl2 eutectic,α(Al)−CuAl2 eutectic, CuAl2+α(Al)−CuAl2 eutectic and Cu9Al4. Additionally, the pouring temperature, cooling mode of the Cu plate surface and start time of the forced cooling after pouring have no effect on the microstructure species. But the proportion of the various microstructures in the transition layer changes with the process parameters. The pure Al at the top of the transition layer starts to solidify first and then theα(Al) phase grows in a dendritic way, while the CuAl2 phase exhibits plane or cellular crystal growth from the two sides of the transition layer towards its interior. The stronger the cooling intensity of the Cu plate outer surface, the more developed the dendrite, and the easier it is for the CuAl2 phase to grow into a plane crystal.%采用浇铝法制备铜铝复合铸锭,研究液体铝与固体铜复合过程中过渡层的凝固过程与组织变化规律,结果表明,铜铝复合铸锭中过渡层由α(Al)+α(Al)−CuAl2共晶、α(Al)−CuAl2共晶、CuAl2+α(Al)−CuAl2共晶和Cu9Al4四种组织组成,浇注温度、铜板外表面强制冷却方式以及浇注后到开始强制冷却时间不影响过渡层内组织种类,但过渡层内各种组织占过渡层厚度的比例随工艺参数而变化。过渡层顶部的纯铝最先开始凝固,而后α相以枝晶的方式、CuAl2相以平面晶或胞晶方式分别从过渡层的两侧向过渡层内生长。铜板外表面冷却强度越强,α枝晶越发达,CuAl2相越容易长成平面晶。
