“…It is also worth noting that the elements that make up austenitic steels, according to the degree of influence on SFE are divided into two types: elements increasing and decreasing its value. It is also known that the stacking-fault energy of austenitic steels is in direct ratio to the deformation temperature, and the grain size of austenite is in invers ratio [25,26].…”

This article provides a brief overview of steels prone to transformation induced plasticity (TRIP), which belong to the class of advanced high-strength steels (AHSS). The necessary set of properties in these steels is formed due to the partial preservation of supercooled austenite in the structure. The article considers the mechanism of TRIP transformation, which depends on the value of the temperature of the beginning of the martensitic transformation. It is shown that the amount and stability of supercooled austenite can be influenced by varying the temperature and time parameters of heat treatment. In addition to heat treatment, the qualitative and quantitative parameters of metastable austenite are significantly influenced by the alloying of TRIP steels, and the alloying elements themselves can be divided into several main groups (ferrite-stabilizing, increasing the stability of supercooled austenite and micro-alloying). In the final part of the article, the prospect of using TRIP steels in the aerospace industry is considered, where reducing the metal consumption of parts is a priority. It is also worth considering that the production of parts using additive technologies is widespread in the aerospace industry. Therefore, the use of TRIP steels as a material in additive manufacturing leads to the formation of a new concept for creating parts with a unique set of properties, primarily with high structural strength, light weight and the possibility of self-adaptation to extreme external exposures.

“…Although a surface hardening is observed in zone 2, this is not desirable. Kolokolsev et al [10] have reported that the decrease in SFE decreases resistance to wear. ; to minimize decarburization during heat treatment, additions of 2.5 percent chromium are common [11].…”

“…In those equations, ρ is the molar surface density along {111} planes, ∆G γ→ε , the molar Gibbs energy of the transformation γ/ε, σ the surface energy of the interface γ/ε, a, the lattice parameter, N, the Avogadro number, R, the gas constant, T, the deformation temperature, β ϕ , the magnetic moment, x i , the atomic fraction, and d, the grain size in microns. Several contributions have been made to the relationships between SFE, microstructure [5,6], and grain size [9], and wear resistance [10,11]. Similarly, the effect of strain rate by impact through shot peeing [12,13], and explosive hardening [14,15] on the microstructure in austenitic steels with 12 mJ m −2 < SFE < 35 mJ m −2 has been studied.…”

This paper presents the characterization of a secondary cone crusher concave liner made of Hadfield steel used in Chilean mining after crushing copper minerals during all service life. During use, a cone crusher concave liner suffers indentation (cold working) and abrasion; this combination provides the concave with a layer that constantly renews itself, maintaining a surface highly resistant to abrasive wear. The results presented here were obtained using optical microscopy, microhardness test, measuring abrasion using the dry sand/rubber wheel apparatus, and x-ray diffraction peaks analysis through the classic Williamson–Hall method. After analysis of results, two hardened surfaces have been found—one a product of heat treatment and the other due to deformation during use. This work proposes ways to explain them; the first one uses a thermodynamic model to calculate stacking fault energy, and the second compares the liner with cold-rolled samples.

“…Abbasi et al [9] studied the abrasive wear behaviour of Al-alloyed Hadfield steel under both high- and low-stress wear conditions in comparison with that of non-Al alloyed Hadfield steel. Kolokoltsev et al [10] studied the resistance of Hadfield steel cooled at different rates. El-Fawkhry et al and Kalandyk et al [11], [12] both discussed the results of austenitic matrix modification in high-manganese steel castings.…”
