摘 要:  借鉴TLP连接技术在其它领域的最新研究进展, 提出利用4045铝合金为中间层材料,采用轧制复合的方法生产不锈钢-3003铝合金复合板的新工艺。 研究结果表明: 在加热温度为570 °C的条件下,依靠轧制过程中产生的变形热, 中间层4045铝合金出现了理想的瞬间液化现象, 复合界面处发生了一系列类似于TLP连接过程的物理冶金行为, 两种基体实现了良好的复合, 复合板的主要力学性能得到了明显的改善。 提出了轧制复合工艺中TLP连接过程的四阶段模型, 认为中间层熔化阶段是该工艺的技术核心。

Abstract: In the light of recent development of TLP joining techniques in other fields, the new technology of preparing bonding plates of stainless steel/A3003 was presented using hot-rolling when A4045 aluminum alloy was used as intermediate materials. The results show that at 570 °C depending on the heat gained from deforming, there are perfect transient liquid phases in intermediate layer A4045 aluminum alloy and a series of physical metallurgical behaviors like TLP jointing process on the bonding interface. The interface of two types of core materials gains good bonding and the main mechanical performances of bonding plates are improved markedly. In the experiment, the model of TLP joining was provided and technical core of this process is the melting step inside intermediate materials.
