对喷射成形＋轧制Ａｌ－Ｐｂ／Ａｌ／Ｓｔｅｅｌ复合板材进行了热处理，用ＳＥＭ观察了Ａｌ－Ｐｂ／Ａｌ及 Ａｌ／Ｓｔｅｅｌ界面的变化．结果表明：复合轧制后Ａｌ－Ｐｂ／Ａｌ及Ａｌ／Ｓｔｅｅｌ界面达到了良好的界面初结合； 复合板材热处理后，Ａｌ／Ｓｔｅｅｌ界面在４８０℃／１ｈ＋３００℃／３ｈ的热处理后产生了ＦｅＡｌ金属间化合物.
The spray-formed + rolled Al-Pb / Al / Steel composite sheets were heat-treated and the changes of Al-Pb / Al and Al / Steel interfaces were observed by SEM. The results show that the interface between Al-Pb / Al and Al / Steel after composite rolling achieves a good initial interfacial bonding. After the heat treatment of the composite sheet, the FeAl intermetallics are produced after the heat treatment at 480 ℃ / 1h + 300 ℃ / 3h Compound.
