MICROALLOYED STEELS FOR THE AUTOMOTIVE INDUSTRY [PDF]

Tecnologia em Metalurgia Materiais e Mineração, 2014
Two major drivers for the use of newer steels in the automotive industry are fuel efficiency and increased safety performance. Fuel efficiency is mainly a function of weight of steel parts, which in turn, is controlled by gauge and design. Safety is determined by the energy absorbing capacity of the steel used to make the part. All of these factors are

Achieving exceptional strength-low temperature toughness synergy in the microalloyed medium carbon steel via layered heterogeneous structure

Materials & Design
The further advancement of microalloyed medium carbon steels is often limited by low-temperature toughness instability. A microalloyed medium carbon steel with both strength and low-temperature toughness was produced through a warm rolling and short-time

Interaction between Microalloying Additions and Phase Transformation during Intercritical Deformation in Low Carbon Steels

Metals, 2019
Heavy gauge line pipe and structural steel plate materials are often rolled in the two-phase region for strength reasons. However, strength and toughness show opposite trends, and the exact effect of each rolling process parameter remains unclear.

Impact properties of microalloyed steels

Metalurgija, 2000
Impact properites of two grades of microalloyed steels (Re>MPa) work hardened by static and dynamic inuaxial tension are presented. Properties are analysed by impact testing at very high impact loading rate (v=785 m/s) and by fatigue testing at ultrasonic, high frequency (20 kHz).

Niobium in Microalloyed Rail Steels

, 2017
Rail steels rely primarily on possessing adequate wear and rolling contact fatigue resistance. These properties, together with the toughness, can in principle be optimized by implementing thermomechanical processing assisted by controlled niobium additions. The purpose of the current work is to develop a Nb-microalloying strategy in the context of high-
