“…These materials are designed to provide a higher level of safety for drivers and passengers and to increase the overall efficiency of road transport. In addition, practical studies of high-Mn steels have recently launched in order to develop technologies for the production and use of such steels as damping elements for seismic resistant structures [6].…”

The microstructures and mechanical properties of Fe-0.4C-18Mn and Fe-0.6C-18Mn steels subjected to large strain cold rolling followed by annealing were studied. Cold rolling with a total reduction of 86% resulted in substantial strengthening at expense of plasticity. The yield strength and the ultimate tensile strength of above 1400 MPa and 1600 MPa, respectively, were achieved in both steels, whereas total elongation decreased below 30%. Subsequent annealing at temperatures above 600 °C was accompanied with the development of recrystallization leading to fine-grained microstructures with an average grain size of about 1 μm in both steels. The fine-grained steels exhibited remarkable improved mechanical properties with a product of ultimate tensile strength by total elongation in the range of 50 to 70 GPa %. The fine-grained steel with relatively high carbon content of 0.6%C was characterized by ultimate tensile strength well above 1400 MPa that was remarkably higher than that of about 1200 MPa in the steel with 0.4%C.

“…Hal ini berbanding lurus dengan hasil simulasi total deformasi yang mana Hooke menyebutkan bahwa suatu benda atau material jika diberikan beban secara terus menerus akan mengakibatkan atau timbul tegangan yang berlebihan pada material tersebut, tegangan yang dihasilkan bisa berupa tarik atau tekan (Fedorenko et al, 2017). Akibat tegangan yang terus menerus maka material akan timbul regangan yang mengakibatkan deformasi yang berlebihan pada material tersebut (Nikulin et al, 2016). Hasil analisis simulasi tegangan normal dapat dilihat pada gambar 6.…”

Motor bakar adalah motor yang dalam cara kerjanya membutuhkan pembakaran dengan merubah energi kimia menjadi energi mekanik. Pembakaran yang sering terjadi dalam ruang bakar dapat mengakibatkan panas dalam ruang bakar dimana pembakaran tersebut membutuhkan gerak bolak balik dari piston. Agar piston dapat berporasi normal maka, dibutuhkan komponen yang kuat untuk mendorong dan menopang piston tersebut. Komponen yang mendorong piston dalam dunia otomotif disebut dengan batang piston. Pemilihan material batang piston harus diperhatikan dengan ketelitian yang tinggi. Salah satu bahan penyusun material yang sering digunakan adalah Al Alloy dan Ti Alloy. Penelitian ini adalah untuk menguji dan menganalisis batang piston dengan metode elemen hingga. Analisis elemen hingga pada batang piston dilakukan dengan bantuan software ANSYS. Simulasi ANSYS dimaksudkan untuk menguji perbedaan total deformasi, tegangan normal, dan safety factor pada masing-masing material. Hasil analisis menunjukkan bahwa deformasi terbesar dialami pada batang piston dengan material Al Alloy dengan nilai 0,672 mm sedangkan pada material Ti Alloy deformasi yang dialami sebesar 0,496 mm.

“…It has recently been demonstrated that Fe-Mn-based alloys, such as Fe-15Mn-10Cr-8Ni-4Si and Fe-30Mn-4Si-2Al, exhibit exceptionally long fatigue lives. [5][6][7][8][9] Specific design criteria formulated by Sawaguchi et al 5) were considered necessary to improve the low-cycle fatigue (LCF) resistance in these alloys. Alloys meeting the proposed criteria exhibit gradual hardening during cyclic deformation, retarded growth of the ε-martensite and planar gliding of extended dislocations in the austenite.…”

We investigate the effects of the annealing microstructure on the low-cycle fatigue (LCF) life (N f ), cyclic stress behaviour and fatigue microstructure of a Fe-15Mn-10Cr-8Ni-4Si alloy that exhibits a deformationinduced transformation of austenite (γ -phase) into ε-martensite (ε-phase). The alloy rolled at 800°C was annealed at 600°C, 700°C, 800°C and 900°C to vary the grain size, the fraction of recrystallised grains and the texture intensity. Fully reversed axial strain-controlled LCF tests were conducted at total strain amplitudes, Δε t /2, ranging from 0.007 to 0.02. The alloy showed a higher N f than common steels and ferrous high-Mn alloys in this strain range. This type of annealing microstructure was found to impact the N f , fatigue behaviour and deformation-induced ε-martensitic transformation (ε -MT) in the studied alloy. The fully recrystallised and weakly textured austenite formed at T ≥ 800°C facilitated the uniform development of ε-martensite under cyclic deformation and led to an increased N f . The partially recrystallised and textured austenite-containing substructure with high dislocation density formed at T ≤ 700°C suppressed the ε-MT, retarded reversible dislocation motions in the un-recrystallised regions and moderately decreased N f . Moreover, N f and the deformation-induced ε-MT were observed to be less sensitive to variations in grain size.
