About Impact Strength and Thermal Properties of Steel Melts

Article Preview

Abstract:

The comparable study of the structure and structure-sensitive properties of the melt of steel 08H15N5D2T and two melts prepared by electro-slag re-melting (ESR) and vacuum-arc re-melting (VAR) of the steel has been carried out. The temperature dependences have been obtained for the kinematic viscosity, density, surface tension, electrical resistance, and magnetic susceptibility. The short-range structural order of the ESR and VAR melts has been studied by direct diffraction methods. The connection between the method of re-melting and the level of impact strength (KCU) has been established. The reasons for the appearance of the difference in the structure and properties of ESR and VAR steel are discussed.
