“…The factors influencing β→α martensite transformation also include the original β-Ti grain size and strain energy [35,36]. The original β-Ti grains of the martensite zone after high-temperature heat treatment are coarse, which leads to a higher Ms temperature due to the decreased strength of the β-Ti phase and decreased number of martensite nucleation sites [37].…”

Ti and V were bonded together and subjected to high-temperature treatment at 1000 or 1100 °C for 16 h to study the microstructural evolution and interfacial behavior of Ti–V diffusion interfaces. The samples were prepared by electro-polishing and analyzed using scanning electron microscopy, electron probe microanalysis, electron back-scattered diffraction, and nano-indentation. The results indicated that Ti–V diffusion bonding interfaces comprises a martensite Ti zone, a body-center-cubic Ti (β-Ti) zone, and a V-based alloy zone. They are divided by two composition interfaces with V contents of ~13.5% and ~46%. The original interface between the pure Ti and the V alloy substrate falls within the β-Ti zone. The observation of acicular-martensite rather than lath-martensite is due to the distortion caused by the β-to-α phase transformation in the adjacent pure Ti. The recrystallization of β-Ti is distributed along the interface direction. The hardness varies across the Ti–V interface bonding zones with the maximum value of 7.9 GPa.

“…In the state after hardening the δ-ferrite is preserved. As a consequence, grains of δ-ferrite surrounded by lath martensite are preserved in the samples where the melting of the upper boundary of the hardened zone did not take place [13]. Therefore, the microstructure of the melting zone after hardening consisted of rack martensite, coarse δ-ferrite and α-ferrite and partial content of γ-austenite [14][15][16][17][18].…”

“…The influence parameters scanning of the laser beam on the depth of the hardened layer was studied. The formation of macro-and microstructural features [13][14][15] during laser hardening was also analyzed. The influence of technological modes and surface temperature on the structure and microhardness of the created samples is revealed.…”

The article presents the results of a research of the process of laser hardening of steel 14Cr17Ni2 (AISI 431) by radiation of a high-power fiber laser LS-16. Assessment of the theoretically possible maximum depth in laser processing without additional beam transformations, the use of additional coatings and devices were shown. The results of experiments on increasing the depth of the hardened layer during laser processing by using scanning of the laser beam and optimally selected mode parameters without scanning are demonstrated. The influence of the number of passes on the depth of the hardened layer is investigated. The microstructure of hardened samples was studied and quantitative estimation of structural components was carried out. The microhardness of hardened samples at different modes of laser hardening was measured.
