Fracture promoting media are comprised of mercury and an alkali metal selected from the group consisting of cesium, lithium, sodium and potassium. A modification of the foregoing media is achieved by the addition of a metallic sulfate solution selected from the group of gold sulfate, silver sulfate and copper sulfate. A method of achieving failure of a material at greatly reduced energy requirements comprises contacting the material at a desired place for failure with a medium of mercury and an alkali metal selected from the group of cesium, lithium, sodium and potassium and applying force to the material. A modification of the foregoing method comprises contacting the material at a desired place for failure with a medium of mercury, an alkali metal selected from the group of cesium, lithium, sodium and potassium and a metallic sulfate solution selected from the group of gold sulfate, silver sulfate and copper sulfate and applying a force to the material.
A fracturing solution for aluminum alloys, titanium alloys, copper-base alloys, iron alloys and steels comprising a first component of 98% to 99.8% mercury and 2% to 0.2% alkali metal selected from the group consisting of sodium, cesium potassium, and lithium and a second component of at least 1% of at least 0.0001N metallic sulfate solution selected from the group consisting of gold sulfate, copper sulfate and silver sulfate.
A method of altering the strength properties of aluminum alloys, copper-base alloys, titanium alloys, iron alloys and steels comprising coating the materials with a composition of mercury and an alkali metal selected from the group consisting of sodium, cesium, potassium and lithium, said alkali metal having a variable range of 0.2 to 2% and the balance being mercury.
A method of fracturing materials comprising the steps of (1) coating the materials in the area in which a fracture is desired with a composition of an alkali metal selected from the group consisting of sodium, cesium, potassium and lithium, said alkali metal having a variable range of 0.2 to 2% and the balance being mercury and (2) applying force to the materials.
A method of embrittling iron containing materials through the introduction of hydrogen into the materials comprising coating the materials with a composition of mercury and an alkali metal selected from the group consisting of sodium, cesium, potassium and lithium, said alkali metal having a variable range of 0.2 to 2% and the balance being mercury.
