Liebermann and Graham

Howard Liebermann and Charles Graham, MSE, developed a new method of manufacturing thin ribbons of amorphous metal on a supercooled fast-spinning wheel.[4] This was an alloy of iron, nickel, phosphorus and boron. The material, known as Metglas, was commercialized in the early 1980s and is used for low-loss power distribution transformers (Amorphous metal transformer). Metglas-2605 is composed of 80% iron and 20% boron, has Curie temperature of 373 °C and a room temperature saturation magnetization of 1.56 teslas.[5]
