Nonmetallic Inclusions and Rolling Contact Fatigue
1975Rolling contact fatigue tests were carried out on an angular contact ball bearing test rig at a low unit pressure (Po = 260 kp/mm2). The results show a sound “relative correlation” between the rolling contact fatigue and the content of nonmetallic inclusions.

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 ...

Transformation of Nonmetallic Inclusions in Steel at High Temperatures
Steel in Translation, 2018The solution of nonmetallic inclusions on heating to high temperatures is analyzed. Dispersion of the inclusions is associated with several processes: dissociation and partial solution of inclusions; diffusional disintegration of inclusions in selective solution; and the formation of disperse satellite particles around the initial inclusions.

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 ...

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.

Nonmetallic inclusion distribution in centrifugal semifinished tubes
Metal Science and Heat Treatment, 1988The investigation of the nonmetallic inclusion distribution along the length of the tube was made in the center portion of specimens with an area of 400 mm/sup 2/ cut across the cross section of the casting. It is shown that in centrifugally cast semifinished tubes of 15Kh1M1F steel the nonmetallic inclusions accumulate primarily at the inner surface ...

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 ...
