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.
