“…This requirement can be defined by metallography (carbide spheroidization analysis) or mostly hardness measurement by maximal value. It leads to a big range in terms of structural conditions and possible trouble for following heat treatments in high-strength applications [1][2][3][4][5].…”

Various structure states before quenching significantly influence final mechanical properties as well as the dispersion of chemical composition at the same steel grade. Therefore heat treatment with mechanical properties is specified in the technical delivery conditions. Even if the heat treatment is determined, different mechanical properties can be achieved. These differences are increasing in importance in high-strength applications like springs, cutting tools, safety, and load-bearing parts of automotive design ect. Because it has a direct impact on their lifetime. The structure consists of ferrite and cementite after spheroidization annealing prior quenching process. The cementite could be observed in various shapes, e.g. fine and large globular particles or the rest of the disintegrated lamellar shape. This article shows how these cementite morphologies affect the quenching behavior and final mechanical properties in high-strength spring steel 54SiCr6. Accelerated Spheroidization, ASR Quenching Spring steel 54SiCr6.

“…Moreover, orientational dependence of mechanical properties, especially Charpy impact and bending properties has been largely reported both in the past and more recently [3,7,[15][16][17]. For instant, it has been observed that formation of typical alpha fiber during hot rolling could have a unfavorable effect on bending properties [17] and can be also associated with the planar anisotropy in direct quenched steels [18]. However, the role of specific crystallographic orientations which are/are not in favor of bending failure and damage is not well stablished yet.…”
