Abstract:
In this paper we present a mathematical model for evaluating the Lankford coefficient (LС) in automotive sheet steels as a function of the ferrite grain size after hot rolling, the degree of cold rolling reduction, the chemical composition, and the volume fractions of perlite and bainite in the final structure. Empirical parameters values of the model were determined using the experimental data base on average LC in 138 strips of 13 steel grades, produced at PJSC Severstal, with a significant range of chemical composition variation.

Abstract:
Speciation and speciation analysis is currently the subject of research in various domains of science and technology, such as chemistry, metallurgy, materials engineering, medicine and environmental protection, being an important factor in the material and environmental analytics development. Speciation is the occurrence of various physical and chemical forms of a given chemical element, the existence of species in tested material. [..]
