* magnetic glass  (in  amorphous solid (physics): Magnetic glasses)

   ...last entry in the Table is an application of metallic glasses having magnetic properties. These are typically iron-rich amorphous solids with compositions such as Fe0.8B0.2 iron-boron and Fe0.8B0.1Si0.1 iron-boron-silicon. They are readily formed as long metallic glass ribbons by melt spinning or as wide sheets by planar flow casting....
* use in steel production  (in  boron (B) (chemical element): Properties, occurrence, and uses)

   Limited quantities of elemental boron are widely used to increase hardness in steel. Added as the iron alloy ferroboron, it is present in many steels, usually in the range 0.001 to 0.005 percent. Boron is also utilized in the nonferrous-metals industry, generally as a deoxidizer, in copper-base alloys and high-conductance copper as a degasifier, and in aluminum castings to refine the grain. In...

性质：硼和铁的合金。根据含碳量，硼铁可分为低碳（C≤0.05%～0.1%,9%～25%B）和中碳（C≤2.5%,4%～19%B）两种。硼铁是炼钢生产中的强脱氧剂及硼元素加入剂。硼在钢中的最大作用是只需极微量即可显著提高淬透性而取代大量合金元素，另外还可改善力学性能、冷变形性能、焊接性能及高温性能等，广泛用于合金结构钢、弹簧钢、低合金高强度钢、耐热钢、不锈钢等。硼在铸铁中可提高韧性、耐磨性，在汽车、拖拉机、机床等制造中有广泛应用。
