（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。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 ...
