Failure characteristics of a dual-phase steel sheet
Failure in ductile sheet metal structures is usually caused by one, or a combination of, ductile tensile fractures, ductile shear fractures or localised instability. In this paper the failure characteristics of the high strength steel Docol 600DP are explored. The study includes both experimental and numerical sections. In the experimental sections, the fracture surface of the sheet subjected t...
متن کاملTEXTURE AND PRESS FORMABILITY OF DUAL-PHASE STAINLESS STEEL SHEET, T. Goto, T. Kondoh, T. Sasaki, Y. Hirose, H. Inoue, pp. 269-274
The press formability of a dual-phase stainless steel sheet consisting of ferrite and austenite phases was estimated from a viewpoint of texture using plastic strain ratios (r-values). From the comparison of the mechanically obtained r-values by tensile test and the r-values calculated from the crystal orientation distribution functions (ODFs) of each phase, we found the ferrite phase contribut...
متن کاملCrystallographic Analysis of Lath Martensite in Ferrite-Martensite Dual Phase Steel Sheet Annealed after Cold-Rolling
The martensite steels produced by quenching and tempering has been used for machine structural use. Martensite in ferrite-martensite dual-phase steels (hereinafter, DP steels) also has important roll in strengthening of the automobile steel sheets. Therefore the importance of analyzing the microstructure and their mechanical properties of the martensite has been increased year by year. Many res...
متن کاملImprovement of Mechanical Properties and Work-Hardening Behavior of Intercritically Annealed Dual Phase Steel
The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...
متن کاملEffect of Laser Welding on Formability of DP980 steel
Limiting dome height (LDH) tests were used to evaluate the formability of laser butt welded blanks of the dual phase 980 steel in comparison with the base metal. Two different lasers were used: diode and Nd:YAG, giving a wide range of welding thermal cycles. A sharp decrease in LDH was observed in the welded specimens due to the formation of a softened zone in the outer heat affected zone. Soft...
