Özet
In recent years, the use of advanced high strength steels in automotive industry has been increased remarkably. Among advanced high strength steels, dual phase (DP) steels have gained a great attention owing to a combination of high strength and good formability. However, high strength usually increases the spring-back behavior of the material, which creates problems for the parts during the assembly. Thus, the uniaxial tensile deformation and spring-back behaviors of DP600 advanced high strength steel were investigated in rolling (0 degrees), diagonal (45 degrees), and transverse (90 degrees) directions in the temperature range from room temperature (RT) to 300 degrees C. All tests were performed at a deformation speed of 25 mm/min. A V-shaped die (60 degrees) was used for the spring-back measurements. The results indicated that the formability and spring-back of the material were decreased with increasing the temperatures. The material showed complex behaviors in different directions and at different temperatures.
