...shattered by the impact: its flat motor hood ripped loose and scythed through spectators like a guillotine knife. The heavy engine followed, spewing parts. The first row of the crowd was cleanly decapitated. Twenty yards away, the chassis cut another swath. Gasoline took fire; then the Mercedes' magnesium-alloy body went up in a searing white flame. Levegh's headless corpse was burned to a crisp. A 400-sq. yd. stretch of gay and cheering people became a black, hysterical horror...
...authorities on raw materials, took over Climax in 1949, the company owned North America's biggest known supply of the metal, in Colorado, but had few buyers. Bunker, 58, went to Washington to argue that the U.S. was in poor shape for the heat-resistant alloy it needed for jet engines, persuaded the Government to start buying...
...high temperature (which favors efficiency) without high pressure, another reactor will have heat-resistant graphite as its moderator and will be cooled by a molten sodium-potassium alloy. Still another will have a novel gimmick. Its cooling water will be allowed to boil, and the steam generated will be used directly to drive a 5,000-kw. turbine. This cuts out the conventional heat exchanger used in the reactor of the submarine Nautilus to generate nonradioactive steam. Dr. Smyth did not say so, but the turbine will probably become so radioactive that it cannot be approached by humans...
This is far stronger than any known metal or alloy. The tensile strength of annealed iron wire is about 60,000 Ibs. per sq. in. The best alloy steel, a carefully contrived structure of many different kinds of crystals, has a tensile strength of less than...
Last week they told about a new alloy, Thermenol, which is made of cheap, plentiful materials (iron, aluminum and a little molybdenum). It resists heat and corrosion better than some kinds of expensive stainless steel, and it is 20 to 25% lighter. Lufcy believes that it may eventually become as common as ordinary iron...
