Role of Nonmetallic Inclusions in Fatigue, Pitting, and Corrosion Fatigue

Corrosion, 1996
A 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 ...

Solidification, Segregation, and Nonmetallic Inclusions

2018
Abstract Many of the structural characteristics of steel products are a result of changes that occur during solidification, particularly volume contractions and solute redistribution. This chapter discusses the solidification process and how it affects the quality and behaviors of steel.

Method for evaluating the content of nonmetallic inclusions in steels

Metal Science and Heat Treatment, 1995
Methods 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, 2007
A 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, 1968
The 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.

Investigation of nonmetallic inclusions in high-speed steels

Materials Characterization, 1997
Abstract The morphology, structure, and amount of nonmetallic inclusions in M2 high-speed steel and an experimental version modified with an addition of Al have been studied. The addition of aluminum to high-speed steel leads to an increase in nonmetallic inclusions, especially Al 2 O 3 and AlN. The morphologies of nonmetallic inclusions in M2Al are

Nonmetallic Inclusions and Fracture Behavior of Steels

Journal of Basic Engineering, 1960
Some 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.

Microstrain distribution near the boundaries of nonmetallic inclusions

Metal Science and Heat Treatment, 1990
Microstrains 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 ...

Rating of Nonmetallic Inclusions by Image Analysis

1975
Image analysis has proved to be a reliable method for the rating of steel cleanness. One analysis gives information about the average content of oxides and sulfides, the existence of critical inclusions according to size, and by specific field counting information related to the macroscopic fraction of inclusions.
