EMBRITTLEMENT OF METALS BY ORGANIC LIQUIDS
Abstract
The published literature on the subject is reviewed. The essential details of reduced fatigue life of steel in the presence of certain polar liquids discovered by Karpenko are confirmed. Studies on polar liquids and solutions were expanded to include a wider variety of long-chain organic species and a number of metalloorganic liquids. It is shown that fatigue life increases with increasing carbon shain length. In all cases the plot of fatigue life against carbon chain length extrapolates to the value for water. Further study has shown that in the presence of a strong dehydration agent, the embrittlement effect disappears. It is concluded that water content in solution is the fundamental factor governing the incidence of reduced fatigue life. However, the mechanism of failure in the presence of water is not clear. A number of experiments are described which suggest that current convictions are not tenable.
