英语翻译
（1） Al3Zr+ZrB2颗粒和基体的热膨胀系数的差异,在基体中形成高密度位错,阻碍了位错间的相对滑动,起到弥散强化的作用.Al3Zr+ZrB2颗粒对于2124合金的强化作用,使得复合材料的强度和磨损性能明显高于2124基体合金,且Al3Zr+ZrB2颗粒分布越均匀、细小,对复合材料机体的强化作用越明显.
（2） 脉冲磁场作用下(ZrB2+A13Zr)p/2124复合材料力学性能的研究结果表明：脉冲磁场能使 (ZrB2+A13Zr)p/2124复合材料中的内生A13Zr和ZrB2增强颗粒在基体中分布变均匀,尺寸变细小,形貌圆整.随着脉冲磁场强度和作用时间的增加,尺寸变小,分布更均匀,而分散的颗粒使得材料的综合性能,尤其是强度和磨损性能有较大的提高.但磁场最佳作用时间为20min左右,超过20min颗粒又有粗化现象.
（3） 磁反应下制备的（Al3Zr+ZrB2）p/2124复合材料和不添加磁场下的复合材料相比,其材料内部Al3Zr+ZrB2颗粒分布明显细小、均匀,耐磨性能都有了明显的提高,特别是在载荷较大时耐磨性能提高幅度更大；随着磁场强度的增加,耐磨性能会进一步增加,但在磁场强度达到某一临界值时,其耐磨性增加的程度很小.

1.The difference between the thermal expansion coefficients of Al3Zr+ZrB2 particles and matrix forms a high density dislocation in the matrix,and it hinders the relative slide within the dislocation,creating a dispersion strengthening effect.The strengthening effect of Al3Zr+ZrB2 particles on 2124 alloy has made the strength and wear-resistance property of the composite material evidently stronger than the 2124 matrix alloy; in addition,if the Al3Zr+ZrB2 particles is more evenly distributed and much finer,the strengthening effect on the matrix of the composite material will correspondingly become more significant.
（2） 脉冲磁场作用下(ZrB2+A13Zr)p/2124复合材料力学性能的研究结果表明：脉冲磁场能使 (ZrB2+A13Zr)p/2124复合材料中的内生A13Zr和ZrB2增强颗粒在基体中分布变均匀,尺寸变细小,形貌圆整.随着脉冲磁场强度和作用时间的增加,尺寸变小,分布更均匀,而分散的颗粒使得材料的综合性能,尤其是强度和磨损性能有较大的提高.但磁场最佳作用时间为20min左右,超过20min颗粒又有粗化现象.
2.The result on the study of the mechanical properties of (ZrB2+A13Zr)p/2124 composite material under pulse magnetic field shows that the pulse magnetic field can make the endogenous A13Zr and ZrB2 reinforced particles within the composite material to be distributed more evenly,the size becomes finer and the shape appearance becomes rounded.As the intensity of the pulse magnetic field and the duration increases,the particle size will become much finer and the distribution more even,resulting in significant enhancement of the comprehensive properties of the composite material,particularly in terms of its strength and wear-resistance property.However,the optimum duration of the magnetic field is about 20 minutes; after that the particles appear to become coarse again.
（3） 磁反应下制备的（Al3Zr+ZrB2）p/2124复合材料和不添加磁场下的复合材料相比,其材料内部Al3Zr+ZrB2颗粒分布明显细小、均匀,耐磨性能都有了明显的提高,特别是在载荷较大时耐磨性能提高幅度更大；随着磁场强度的增加,耐磨性能会进一步增加,但在磁场强度达到某一临界值时,其耐磨性增加的程度很小.
When comparing the composite material prepared without magnetic field,the endogenous Al3Zr+ZrB2 particles within the（Al3Zr+ZrB2）p/2124 composite material prepared under magnetic field reaction evidently show a fine and even distribution,and a significant enhancement in their wear-resistance property,the enhancement range will be even higher particularly when the fatigue load is greater.As the magnetic field grows stronger,the wear-resistance property will increase correspondingly; but when it reaches a critical value,the increase in wear-resistance will be very small.
注：在1和2 里所提及的磨损性能,我认为是耐磨损性能的笔误,所以我的翻译是以后者为准.如果我错了,请做相应的调整.另外,在3 里所述的载荷,我认为应该说明是疲劳载荷,英语翻译也是以后者为准.
