摘要:... The critical embrittlement temperature decreases from −30 to −40°Cto −60 to −70°C.(#br) 3. The sensitivity to stress concentrations and the resistence to mechanical aging, and also the weldability and the resistence of welds to vibrations in MSt. 3 steel are th...

摘要:Abstract(#br)This article describes a large in-service embrittlement study concerning six separate series of steam turbine casing bolts involving nearly four hundred individual bolts. The bolts, which ranged in size from 300 to 1400 mm in length, were fabricated from low alloy ...

摘要:Hydrogen embrittlement threshold curves were derived for two quenched and tempered steel grades, AISI 4135 and AISI 4340, at varying hardness ranging from 33 to 54 HRC. For each material, hydrogen was introduced (i) by zinc electroplating as a worst case condition for internal hy...

摘要:... Using the results of testing samples with circumferential notches for uniaxial tension, the threshold values of a special indicator of reserve properties of strength and ductility of steels—deformation endurance (break resistance) $B_{rb}$ are determined. Below these val...
