The Effect of B

  • Joshua PellegEmail author
Part of the Engineering Materials book series (ENG.MAT.)


Small additions of B improve the room temperature ductility of many intermetallic compounds CoSi2, MoSi2 and TiSi2 among them. Segregation of B to grain boundaries strengthen them. The outstanding feature of B is on inducing ductility in brittle material. Also the oxidation resistance is improved as exemplified for MoSi2 and pest formation is eliminated. Hardness and fracture toughness are higher in B added silicides as illustrated for MoSi2. B added TiSi2 coatings are an example of the effect of B additions, but no direct evidence of the effect of B on the mechanical properties exists, probably because efforts were directed to evaluate its use in VLSI.
