“…Laser scanning confocal microscopy (LSCM) is an appropriate technique to perform in-situ observations of metallic alloys at high temperature. It has already been used to track the motion of a solid-liquid interface in a variety of contexts [5][6][7][8][9][10][11], but until now, always to observe the growth of a solid layer. Although melting was observed and is mentioned in [11], to our knowledge the only detailed study of melting using LSCM is the one of Attallah et al who investigated the melting temperature of γ′ particles in a Ni-base superalloy [12].…”

“…It is reported that the interface layer between steel substrate and the Fe-Cr-C alloy is austenite, and its thickness can be well controlled by a suitable time at 1250uC. 25 By the input energy, steel substrate is heat affected. Meanwhile, the chemical composition at bottom of the coating is diluted by the substrate.…”

With excellent wear resistance, hypereutectic Fe-Cr-C coatings have caused great attention in the field of surface engineering. In this study, the hypereutectic Fe-Cr-C hardfacing coatings with certain amounts of titanium (Ti) additives were further developed. The precipitation of the carbides in the coatings was calculated. The microstructure of the coatings was observed and the phase structure of the coatings was determined. Besides, the wear resistance of the coatings was also measured. The experimental results show that the microstructure of the coatings mainly consists of primary (Cr,Fe) 7 C 3 carbide and eutectic matrix. With increasing Ti additive, the primary carbide is refined, which in turn improves the wear resistance of the coatings.

“…Many researchers state that the microstructure of spheroidizing heat treated steel shows similarity to the microstructure of martensite over-tempered at high temperatures [5]. Quenched and tempered steels are commonly used in the production of gear wheels, axle shafts and spindle arms which are various automobile parts and in parts having a high degree of abrasive wear [6,7].…”

In this study, the effects of microstructure differences obtained with the application of different spheroidizing heat treatment cycles on medium carbon steel on cutting forces and surface roughness values were investigated. For this purpose, a group of AISI 1050 materials was annealed at 700• C below Ac1 temperature for 720 min and cementite phases were spheroidized by the traditional method. Another group of materials was quenched after austenitization at 850• C for 15 min and then cementites were spheroidized in the ferrite matrix by over-tempering separately at 600• C for 15 and 60 min and at 700• C for 60 min. Machining of the samples was tested under dry cutting conditions in CNC turning center with SNMG 120408 cementite carbide cutting tool and proper PSBNR 2525M12 tool holder with 75-degree edge angle. Cutting forces of traditionally spheroidized samples were lower than the samples spheroidized after quenching. In addition, their cutting forces decreased due to the increase in the average sizes of spheroidal cementite. Minimum surface roughness value was obtained from the samples which were spheroidized at 600• C for 15 min after quenching. However, surface roughness rate of the sample increased as spheroidizing time increased. K e y w o r d s : spheroidizing, cutting forces, surface roughness, medium carbon steel
