Strongly surface-active media to intensify mechanical working of metallic solids and other materials

Liquid and Solid Metal Embrittlement

“…Although metal-induced embrittlement is usually to be avoided, workers in the Soviet Union have utilized liquid metals, such as Pb-Sn eutectics, to facilitate drilling steels, Ni-Cr heat resistant alloys, titanium alloys, and others (3,4). Improvement achieved with liquid metals included increased drill life and improvement of the quality of machined surfaces.…”
