Analysis of application of various materials for manufacturing parts of motor car bodies in automobile industry

The work presents an analysis of applying various steels for manufacturing motor-car bodies. There is a brief description of cold-rolled sheet steels RRST 1405 produced according to the standards DIN 1623 and DIN 1541; UST 1203, UST 1303 according to DIN 1624 and DIN 1606; ST 4, 08MnSiAlTi, 07MnNbAl and also a classification and a brief description of steels made according to USLAB: IF-steel with increased formability, thermo-strengthened BH-steel, dual phase (DP) steels, transformation induced plasticity (TRIP) steels, martensitic (Mart) steels, austenitic high-tensile steels ? (TWIP) steels, high strength steels of new generation of AHSS type (advanced high-strength steels) and UHSS (ultra high-strength steels), high-strength steels and superplastic steels of new generation for lightweight constructions (TRIPLEX-steel), hot-rolled nano-structured steel NANOHITEN. It has been shown that the main tendency in modern approach to engineering and manufacturing sheet steel used in automotive industry is to increase strength while maintaining formability characteristics, reducing the coefficient of normal plastic anisotropy (Lankford value ratio), as well as increasing srengthening at deformation. The advantages and disadvantages of the materials used in the automotive industry have been shown, as well as ways of their improving. The work represents a compilation of several publications. The materials can be used for developing a training course ?Materials to be used in transport? within the framework of the International Project on reforming curricula TEMPUS ?MMATENG?: ?Two-stage Training Program for Engineering Materials Curriculum Modernization?
