    摘要:

    鎂和鎂基合金是重要的輕量化金屬材料,廣泛應(yīng)用于汽車、通訊、航空等領(lǐng)域。由于鎂合金熱膨脹系數(shù)較高,當(dāng)應(yīng)用于精密器件時(shí)易導(dǎo)致組裝精密度降低、力學(xué)性能下降等問(wèn)題。因此需要研發(fā)低熱應(yīng)變鎂基材料,以滿足此類應(yīng)用的要求。本文對(duì)降低鎂合金熱膨脹系數(shù)的原理及方法進(jìn)行綜述,歸納比較了合金化、復(fù)合材料和特殊加工工藝等調(diào)整鎂合金熱膨脹系數(shù)的主要方法的原理,總結(jié)出高熔點(diǎn)元素合金化、高硬度顆粒摻雜、低熱膨脹系數(shù)纖維摻雜以及熱處理結(jié)合擠壓加工方法等降低鎂合金熱膨脹系數(shù)的有效方法,并對(duì)未來(lái)該領(lǐng)域的研究趨勢(shì)進(jìn)行了展望。

    Abstract:

    Magnesium and magnesium-based alloys are important lightweight metal materials, which are widely used in automobile, communication, aviation and other fields. Due to the high thermal expansion coefficient of magnesium alloy, the assembly precision and mechanical properties of magnesium alloy are easily reduced when it is applied to precision devices. Therefore, low thermal strain magnesium-based materials need to be developed to meet the requirements of such applications. In this paper, the principles and methods of reducing the thermal expansion coefficient of magnesium alloy are reviewed, and the main methods of adjusting the thermal expansion coefficient of magnesium alloy, such as alloying, composite materials and special processing technology, are summarized and compared. The methods of reducing the thermal expansion coefficient of magnesium alloys, such as alloying with high melting point elements, doping with high hardness particles, doping with low thermal expansion coefficient fiber and heat treatment combined with extrusion processing, were summarized, and the future research trends in this field were prospected.
