Niobium Alloyed High Strength Steels for Automotive Applications
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...
متن کاملMicrostructural control of the austenite stability in low-alloyed TRIP steels
We have performed in-situ magnetization and high-energy X-ray diffraction measurements on two aluminum-based TRIP steels from room temperature down to 100 K in order to evaluate amount and stability of the retained austenite for different heat treatment conditions. We have found that the bainitic holding temperature affects the initial fraction of retained austenite at room temperature but does...
متن کاملMicrostructural Characterization of Carburized Steels
*Member of ASM International arburizing has been a popular method for obtaining a unique balance of properties in steels for many years. Steels with low carbon contents are characterized by good toughness and good ductility, but low strength and low wear resistance. By locally increasing the carbon content at the surface, followed by heat treatment to produce a very high hardness in this layer ...

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 ...
