Metals, 2021 In the past decade, efforts have been focused on developing very fine, medium-carbon bainitic steels via the low-temperature (typically 300–400 °C) ausforming process, which not only enables shorter isothermal holding times for bainitic transformation at

Ironmaking & Steelmaking, 2016 This review considers the compositions, the main process routes, microstructure, and structural properties of microalloyed steels. The background and brief history are followed by sections dealing with aspects of precipitation which control grain size and dispersion strengthening in ferrite- pearlite steels, the approaches to modelling thermomechanical

Microalloyed Steels for Car Parts
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The composition and properties of three constructional microalloyed steel with vanadium, niobium and nitrogen is investigated. High strength and ductility steel in rolling mill products and in forgings were revealed, manufactured according to various flow diagram.

Static Recrystallization Behavior of Low-Carbon Nb-V-Microalloyed Forging Steel
Metals, 2022 Static recrystallization is a method of tailoring the microstructure and mechanical properties of steels, which is important for microalloyed forging steels as the hot deformation process significantly affects their mechanical properties.

Journal of Materials Research and Technology, 2022 API 5L X65 microalloyed steels are extensively used for oil and gas transportation. In many cases, reserves of such resources contain H2S, constituting what is called a sour medium, at which hydrogen-induced failures are critical.

Influence of the Strain Rate on the Notch Toughness of Cold-Forming Steels
Communications, 2004 The paper analyses the influence of the strain rate with loading rates of 1.7.105 4.8 m.s1 on the notch toughness of hot-rolled microalloyed steels S 315 MC and S 460 MC and cold-rolled deep-drawing steels DC 06, H 220 B and H 220 P.

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...
