Niobium Alloyed High Strength Steels for Automotive Applications
نویسنده
چکیده مقاله:
Modern vehicle bodies make intensive use of high strength steel grades to meet the contradicting demand of lighter weight and simultaneously better mechanical performance. For many steel grades microalloying by niobium is the key to achieve their characteristic property profile. In HSLA steels niobium enhances the strength primarily by grain refinement. In interstitial free high strength steels niobium serves as a stabilizing element. Some modern multiphase steels rely on niobium to achieve additional strength via grain refinement and precipitation hardening. Microstructural control constitutes a powerful means to further optimize properties relevant to automotive processing such as cutting and forming. The role of niobium microalloying in that respect will be outlined.

متن کاملDetermination of Niobium precipitations in micro alloyed steels
Micro-alloyed High Strength Low Alloy steels (HSLA-steels) are widely used in civil construction, automobile and line pipe applications. They contain small quantities of alloying elements between 0,01 – 0,1 wt%, such as Niobium, Titanium, Vanadium, Aluminium and Nitrogen. These steels rely on thermo-mechanical rolling, a technique that simultaneously provides high strength, excellent toughness ...
متن کاملLaser welding of modern automotive high strength steels
The paper demonstrates the correlation between the chemical composition of steel grades and the hardness as well as the formability of laser welds generated with modern automotive high strength steel grades. At the very low heat input of industrial laser welding and the resulting extremely high cooling rate, the weld hardness is fully controlled by the carbon content of the base materials and n...
متن کاملHigh-Strength Bainitic Steels
With careful design, mixed microstructures consisting of fine plates of upper bainitic ferrite separated by thin films of stable retained austenite have exhibited impressive combinations of strength and toughness in highsilicon bainitic steels. The silicon suppresses the precipitation of brittle cementite leading to an improvement in toughness. The essential principles governing the optimisatio...
متن کاملDamage Behavior in Modern Automotive High Strength Dual Phase Steels During Uniaxial Tensile Deformation
In the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,DP780 and DP980, were studied. Detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (SEM). The results revealed that interface decohesion, especially at the triple junctions of...
