Role of Nonmetallic Inclusions in Fatigue, Pitting, and Corrosion Fatigue
Corrosion, 1996A study was conducted of the effect of nonmetallic inclusions on the fatigue and corrosion fatigue resistance of a high-strength steel in 0.6 M sodium chloride (NaCl) solutions. Results indicated that angular calcium-aluminate inclusions played an important role in introducing cracks during air fatigue cycling; however, sulfide inclusions appeared to ...

Nonmetallic Inclusions and Fracture Behavior of Steels
Journal of Basic Engineering, 1960Some observations showing the adverse effects of certain kinds of nonmetallic inclusions on the strength and fracture behavior of alloy steel test specimens are presented. The observations pertain to the effects in tests at low and high temperatures and under steady and cyclic loading.

Effect of nonmetallic inclusions on properties of cast steel
Soviet Materials Science, 1968The result's of a study of the effect of nonmetallic inclusions on physicochemical and electrochemical properties of steel 45L are reported. A new (linear) method of determining the content of nonmetallic inclusions in steel, which makes it possible to determine also the shape of inclusions, was used.

Method for evaluating the content of nonmetallic inclusions in steels
Metal Science and Heat Treatment, 1995Methods for evaluating the content of nonmetallic inclusions in ShKh 15, ShKH5SG, and ShKh20SG steels used for rolling bearings are considered. These methods can be applied to other steels used for various parts that fail in operation due to fatigue spalling.

Influence of nonmetallic inclusions on the fatigue strength of metals
Materials Science, 2007A model of growth of short fatigue cracks in the vicinity of nonmetallic inclusions in crystalline metallic materials is proposed. We establish the influence of inclusions on the fatigue strength of materials of this type. A conclusion is made that the inclusions whose typical size is smaller than the grain size exert practically no influence on the ...

Microstrain distribution near the boundaries of nonmetallic inclusions
Metal Science and Heat Treatment, 1990Microstrains were measured on a flat alloy 35KhN3MF specimen using photographically superposed small-base scaling grids. The base of the grid 0.01 mm corresponds to the characteristic grain size, and the specimen deformation is 10.2%. The field of micro-strains was examined in the zone of three inclusions located in segments with local longitudinal ...

Simulation of Nonmetallic Inclusions in a Continuous Casting Strand
steel research international, 2005The liquid steel flow and the particle transport of non-metallic inclusions in the liquid domain inside the strand of a continuous steel casting system are numerically investigated. The whole liquid domain inside the solidified shell is simulated, and the loss of liquid steel due to solidification is considered.

Influence of nonmetallic inclusions on endurance of percussive machines
Journal of Mining Science, 2011Based on the results of the industrial testing of downhole hammers with underreamers and on the analysis of the influence exerted by nonmetallic inclusions in steel on the steel fatigue endurance under the impact load, it has been shown that the stringer-type nonmetallics greatly aggravate the steel endurance both under compression and bending ...

Cathodoluminescence analysis of nonmetallic inclusions of nitrides in steel
Surface and Interface Analysis, 2018Identification of nitride inclusions such as boron nitride (BN) and aluminum nitride (AlN) is important in the steelmaking industry because BN inclusions deteriorate the creep strength of ferritic heat‐resistant steel, and AlN inclusions cause transverse cracking in twin‐induced‐plasticity steel.
