Abstract
Review of weakness mechanism of grain boundaries cohesion by segregati on of impurities is given in present paper. Grain boundaries segregati on of impurities in steels leads to the changes of bonding energy in t his locality. Grain boundary cohesion energy reducing by impurities se gregation leads to corresponding lowering of applied local stress requ ired for grain boundary brittle fracture occurrence. In the paper some cohession strength measurement methods are discussed.
