...must be stronger than steel, lighter than aluminum, heat resisting, tough. Metallurgists have not compounded it. But some 6,000 of them felt that they were approaching the goal as they listened to metallurgical discourses of the National Metal Congress held last week at Cleveland, the Foundry City.* Manganese-Molybdenum Steel. Hard and sharp were the Samurai swords of Japan, the Toledo blades of Spain, the Damascus cutlery of the Levant-because their steels contained small amounts of molybdenum. However, the presence of molybdenum was accident. Mineralogists did not recognize it as a metal until the 1790's. Metallurgists...
...bicycle's wing skeleton is made of chrome molybdenum, that strong, light, beautifully tempered metal whose high value was discovered during the War, which has become important in airplane construction. This framework is covered with noninflammable celluloid upon the surface of which are distributed many "feathers" (strips of the molybdenum). The whole machine weighs 117 pounds, can be built...
...main feature of the invention, the "window." This constituted a vast improvement upon the aluminum disc of earlier experiments. It was a sheet of nickel 1/2000 of an inch thin and three inches in diameter, supported against the 100-pound suction of the vacuum tube by skeleton struts of molybdenum. The molecular structure of nickel is such that molecules of air (oxygen, nitrogen) cannot pass through it, though it offers a minimum of resistance to those billionth parts of molecules, electrons...
