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.

Nonmetallic inclusion distribution in centrifugal semifinished tubes

Metal Science and Heat Treatment, 1988
The 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, 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.

Titanium-bearing nonmetallic inclusions in manganese ferroalloys

Steel in Translation, 2010
Petrographic data indicate the chemical and mineralogical composition, topography, and morphology of various titanium-bearing nonmetallic inclusions of the type TiS, MnS-TiS, TiS-α-SiC, and TiS-MnS-TiC, as well as nonstoichiometric titanium sulfides and titanium carbonitrides.

Effects of Nonmetallic Inclusions on the Fatigue Strength of Metals

1990
The equation for predicting the effects of artificial small defects on the fatigue strength of metals is introduced, and it is applied to evaluate quantitatively the effects of nonmetallic inclusions on the fatigue strength of high-strength steels. It is emphasized that the concept that nonmetallic inclusions are virtually equivalent to defects, from ...
