“…Experiments using such samples include the measurement of lattice parameters by X-ray diffraction, [7][8][9][10][11][12] synchrotron radiation X-ray diffraction, 13) neutron diffraction, 14,15) the measurement of thermal expansion coefficients, 10,11,[13][14][15] and measurements of X-ray elastic constants. [16][17][18] In addition, hardness measurement [19][20][21][22][23][24][25][26][27] and the measurement of Young's modulus by nanoindentation 27,28) were also performed using such samples. The second type involved the use of various samples with different volume fractions of cementite.…”

“…When discussing elastic constants, attention should be paid to the quantity of alloying elements in cementite. Table 3 [16][17][18]25,[29][30][31][32][33]40,41,50,51,57,70,71) is a summary of the experimental elastic constants of cementite reported after 1950. The table presents only data obtained using samples without alloying elements or samples with precise amounts of alloying elements.…”

This review focuses on the mechanical properties of single-phase cementite. The mechanical properties of interest are 1) sound velocity, 2) elastic constants, 3) hardness, 4) plastic deformation mechanism, 5) wear, 6) fracture toughness, and 7) crystal orientation anisotropy. The effects of temperature, magnetic transition, and alloying elements on the sound velocity, elastic constants, and hardness were reviewed. Furthermore, experimental values of the above mechanical properties as well as other parameters, such as the specimen shape, the quantity of alloying elements, and the measurement method, were collected. A large variation was observed in the reported experimental values. The main reason for this is that cementite is metastable, and it is difficult to prepare large single-phase samples. Other factors, such as sample shape, measurement method, alloying element, magnetic transformation, and crystal orientation anisotropy, also influenced the measured values. Studies using first-principles calculations of cementite were also reviewed. The crystal orientation anisotropy of each elastic constant of single-crystal cementite based on the first-principles calculations are summarized, and its comparison with the experimental results is discussed. By comparing the elastic constants obtained by the first-principles calculations with the measured values, the former values of Young's modulus and shear modulus are several % and bulk modulus and Poisson's ratio are several tens of % larger than those of the latter. This is thought to be because of the difference in temperature between 0 K (first-principles calculations) and room temperature (measured value), and theoretical and experimental studies in which the temperature is changed are expected.

“…In the case of JIS SK5 and SK3 carbon steels, Lei et al [12] showed various stress partitioning under loading and after unloading as a function of volume fraction and particle size of spheroidal cementite. Moreover, the authors observed an elastic behavior of cementite and ferrite when the spheroidized carbon steels are elastically loaded.…”

“…The mechanical characteristics, hardness and toughness of steels depend on microstructural characteristics such as the size of the old austenitic grain [16,17] the interlamellar spacing [18][19][20], the volume fraction of cementite and its morphology [21].Improving mechanical properties, such as hardness increases the wear resistance of materials and plays a primary and important role in the longevity of mechanical parts of machines (CNC) and reducing energy loss [22].Quenching and tempering make it possible to modify and improve the mechanical properties of steel: elastic limit, tensile strength, toughness, hardness and resilience.…”

This study concerns the wear behaviour of metal couples used in industry, particularly in mechanical sliding systems (numerically controlled machine tools). In general, the nature of the materials of the parts of these systems which are in contact and move relatively, are medium carbon steels, thanks to their good mechanical and tribological properties. The present work aims to study, the dry sliding wear of the contact surface of the pin (machine slide) against the contact surface of a disc (machine groove) and the damage induced on the worn track. The pin is AISI 1038 and AISI 1045 steel, the disc is AISI 1055 steel. The tribological tests were carried out on a pin-disc tribometer, in an atmospheric environment. The wear of the pins being evaluated by weighing and studied according to the hardness of the pin with the variation of the normal load applied. The discussion of the results is based on SEM observations and EDS analyzes of worn surfaces and interfacial phenomena produced by dynamic contact. The results obtained indicated the influence of the applied load and the hardness on the wear of the pin and therefore on the tribological behaviour of the worn surfaces.
