Özet

Turkey has started the integrated steel production with the foundation of Karabuk Iron-Steel Factory which is the first heavy industry attempt of the country. Even though Turkish Iron-Steel industry has been exposed to various crises until the 21(st) century, it took an important step into a growth process starting from the year 2001. However, to keep up with the sectoral changes developing in the global economy and to direct the production in accordance with such developments have become a requirement. For this purpose, it might be an important objective to produce steel for the automotive industry that has come into prominence in our country with a high level of added value and income. Production of light and advanced high-strength steel for Turkish and World industries is a very critical technology. In developed countries, the steel industry is based on integrated plants and has been directed to products such as advanced high-strength steel, stainless steel, etc. that have a very high added value. In spite of that different kinds of steel sheet are being produced in our country, the dual phase steel which has been intensively utilized especially in recent years is being produced in low quantities whereas TRIP steel, which shall be used more with the purpose of reducing the weight of the vehicles in future, is not being produced. The literature study has done considering most recent research shaped within the frame of original studies conducted in recent years. In this study, TRIP steels have been introduced in comparison with other steels used in automobiles based on certain criteria such as microstructure, tensile strength, crash (impact), formability and fatigue. Furthermore, a study has also been conducted about the utilization of the TRIP steel in automotive industry and manufacturability in Turkey.
