金属基复合材料的热膨胀

THERMAL EXPANSION OF METAL MATRIX COMPOSITES

在过去几十年里,研究人员倾注了大量的精力来研究金属基复合材料,取得了很多的成果。热膨胀作为这类材料重要的、基本属性之一也得到了广泛深入的研究。本文主要论述了金属基复合材料的热膨胀研究现状,以及典型的金属基复合材料热膨胀系数模型,并预测了今后的发展方向。

During the past decades, considerable research effort has been directed towards the development of metal matrix composites (MMCs) , and much progress has been made. Thermal expansion, one of the most important and basic properties for MMCs, has also been studied widely and deeply. In the review, the current state on the thermal expansion of MMCs is addressed, the typical physical models of coefficients of thermal expansion (CTEs) are given, and the developing trend of thermal expansion for MMCs is predicted as well.
