摘要

研究了微量合金元素Si、B对铸态QAl9-4铝青铜组织与性能的影响

其中Fe、Si、B以铁基非晶合金的形式加入。结果表明

加入铁基非晶合金的QAl9-4铝青铜与加入工业纯铁的QAl9-4铝青铜铸态下的相组成均为α+β′+k

但前者组织更加细小、均匀;加入铁基非晶合金的QAl9-4铝青铜的抗拉强度为589 MPa、硬度（HB）为141、伸长率为29.9%

与加入工业纯铁的QAl9-4铝青铜相比

分别提高了21.8%、15.0%和9.9%。另外

两种合金的主要磨损形式均为磨粒磨损和粘着磨损

加入铁基非晶的QAl9-4铝青铜耐磨性较好。

Abstract

The effects of Fe-based amorphous alloys on microstructure and properties of the as-cast QAl9-4 aluminum bronze were studied. The results reveal that the phase composition of QAl9-4 aluminum bronze with Fe-based amorphous alloy or pure iron is α+β′+k

however

the former is smaller and more uniform. The tensile strength、Brinell hardness and elongation of QAl9-4 aluminum bronze with Fe-based amorphous alloy are 589 MPa、141 HB、29.9%

increased by 21.8%、15.0% and 9.9% compared with those of ones with pure iron

respectively. In addition

the main wear mechanism of the two alloys are characterized by abrasive wear and adhesion wear

and the wear resistance of QAl9-4 aluminum bronze with Fe-based amorphous alloy is more satisfied.
