anisotropy in steel plates

Yield Strength Anisotropy of Steel Sheet Induced by Grain

In crystal plasticity models the crystal anisotropy of the yield strength is accounted for by the yield locus.In the present paper the full constraint Taylor model is used to calculate the yield strength anisotropy of a heavily cold rolled and annealed IF steel.In addition to the crystallographically induced anisotropy also the grain shape anisotropy was taken into account.Toughness Anisotropy in Intercritically Rolled Steel PlatesThe toughness anisotropy in steel plates (0.08%C,1.52%Mn,0.3%Si,0.055%Nb and 0.078%V) was studied in relation to the crystallographic texture and microstructural anisotropy of the material.The plates,with a ferrite pearlite microstructure,were obtained by hot rolling in a laboratory reversible rolling mill to 66% reduction with the final rolling pass in the two-phase (g/a) domain The anisotropy of tensile propertieson a steel plate can,potentially,generate catastrophic failures during application.Critical examples can be found in line pipe steels for oil and gas transportation and OCTG structural pipes,where exploration occurs in increasing depths and pressures.AIST - 2019 AISTech Conference ProceedingsWas this helpful?Mechanical Anisotropy in Steels for PipelinesMechanical anisotropy of the steel is essential because of unavoidable chemical segregation and/or thermomechanical working.Especially,the anisotropy of toughness is a particular problem,with toughness depending on the orientation relative to the rolling direction.

Fatigue anisotropy in cross-rolled,hardened medium carbon

Anisotropy of forged steel components is especially adverse when it concerns rotationally symmetric components.Manganese sulfides (MnS) in steels may be desired for their improvement of machining properties; however,they also deteriorate fatigue behavior.A quantification of the effect of MnS on anisotropy is necessary to find an optimum for component dimensioning.Effect of Crystallographic Texture on Anisotropy of The thermomechanical control process (TMCP) is widely applied as one of the effective processes for improving the strength and toughness of steel plates.In actual application,the anisotropies of mechanical properties arising from the crystallographic texture developed during the controlled rolling process are important issues.EP1978121A1 - HIGH-STRENGTH STEEL SHEET OF 450 MPaA high-tensile steel plate of low acoustic anisotropy and high weldability having yield stress of 450MPa or greater and tensile strength of 570 MPa or greater and a process for producing the steel plate are provided.The steel has an Si content of 0.10% or less,thereby achieving a volume ratio of island martensite of 3% or less,contains Nb 0.025% and Ti 0.005% so as to satisfy 0.045%
