In this paper the study was carried out on the compound technology of H90/q195 cladding sheet,with different temperature rolling.

The technology of roll-bonding was applied to prepare the foaming precursor in this paper.

Author studied the production technology of aluminum foam sandwich prepared by roll-bonding/powder metallurgy foaming process in this paper,and analyzed the effect of main technological conditions on foaming structure of sandwich layer,and optimum technological parameters were finally obtained.

The dynamic temperature field during roll-bonding combined with high-frequency alternating current heating has been numerically simulated by a simplified model.

A powder-A1 plate sandwich rolling processing is proposed for preparation of aluminum alloy foam sandwich with a metallurgy bonding interface.

The foam aluminum sandwich panels with metallurgy bonding interface are prepared by the sandwich rolling method,the two Al face-sheets are stacked and mixed powders with foam agent are put between them,which are sandwich rolled and a foaming precursor is obtained,then it is foamed in heating furnace.

surface processing+composite rolling+heat treatment were carried out.

By the experiment of rolling stop,on the basis of analying the law of the composite rolling deformation of the double metals,the article derives the theoretical formulation of calculation of layer thickness ratio on the composite material of the double metals,and the error is less than 5% according to the check by the results of actual test.

The principle of layer thichness ratio is studied experimentally in the process of Al-steel composite rolling and the formulation of rolling force was established.

The effect of annealing at low temperatures for long time and at high temperatures for short time on the formability and bonding strength of Cu/Al/Cu rolling clad sheet has been studied and the reason that the annealing strengthening did not appear in this process has also been discussed.
