EMBRITTLEMENT OF METALS BY ORGANIC LIQUIDS

Abstract

High-strength steel and aluminum are shown to be embrittled in notched fatigue testing in the presence of water, alcohols, glycols, ethers, and aldehydes. It is shown that longer carbon chains, branching molecular shapes, and closed rings reduce the degree of embrittlement while multiplicity of (-OH) or (-O-) groups enhance it. By a variety of experiments and deductions, water is shown to behave more like a zero chain length organic molecule rather than an electro lytic medium.
