摘要: <正> 近年来,SiCw/Al复合材料引起了人们的注意。研究表明:SiCw/Al复合材料具有接近于铝的比重和钛的强度,以及超过铝-锂合金的弹性模量,是一种很有前途的新型材料。随着碳化硅晶须和复合材料制造技术的发展,以较低费用大量生产SiCw/Al复合材料及其构件已有可能。SiCw/Al复合材料的断裂韧性已有所研究,但在腐蚀介质中的力学行为却未见报导。本工作在于探明SiCw/Al复合材料在3.5%NaCl水溶液中的应力腐蚀特性,确定其应力腐蚀强度因子K_(ISCC),并讨论应力腐蚀开裂机理。

Abstract：The stress corrosion cracking,behavior in 3.5%NaCl aqueous solu- tion of SiC-/Al composite made by a squeeze casting method was investigated.The results showed,that the SiCw/Al composite was susceptible to stress corrosion cracking.The Kiscc was about 4.8-8.1 MPa which was only 1/2.5 of the Kic value.The mechanism of stress corrosion cracking of SiCw/Al composite was discussed on the basis of observation of fractograph with scanning electron microscopy.
