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 ...

Simulation of Nonmetallic Inclusions in a Continuous Casting Strand

steel research international, 2005
The 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, 2011
Based 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, 2018
Identification 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.

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.

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 ...
