Effects of Ni and Cu addition on cryogenic-temperature tensile and Charpy impact properties in austenitic 22Mn-0.45C–1Al steels

Effect of Texture and Temperature on Strain‐Induced Martensitic Transformation in 304 Austenitic Stainless Steel

“…[ 16 ] Furthermore, the stress caused by additional deformation is predominantly accumulated along the mechanical twins or ε‐martensites, and it can contribute to overcoming the activation energy of γ→α′ martensitic transformation. [ 6,18–20 ] It means that the ε‐martensites form faster than α′‐martensites at cryogenic not room temperature conditions, and play an intermediate role in γ→α′ martensitic transformation in company with the mechanical twins.…”

“…[16] Furthermore, the stress caused by additional deformation is predominantly accumulated along the mechanical twins or ε-martensites, and it can contribute to overcoming the activation energy of γ!α 0 martensitic transformation. [6,[18][19][20] It means that the ε-martensites form faster than α 0 -martensites at cryogenic not room temperature conditions, and play an intermediate role in γ!α 0 martensitic transformation in company with the mechanical twins. Figure 6, 7, and 8 show the EBSD IPF, image quality (IQ), and phase maps at each interrupted strain in the RD and TD samples at room temperature and the RD sample at cryogenic temperature, respectively.…”

Pengaruh Variasi Persentase Reduksi pada Proses Pengerolan Panas terhadap Sifat Mekanik dan Struktur Mikro Baja Laterit

“…Kekuatan impak material menunjukkan ketahanan material terhadap pembebanan impak. Kekuatan impak dapat dilihat pada energi yang terserap oleh spesimen selama pembebanan impak sampai material tersebut patah [24]. Semakin besar energi yang diserap maka material semakin ulet dan mengalami patah ulet.…”

Effects of cerium addition on the microstructure, mechanical properties and strain hardening behavior of TWIP steel Fe-18Mn-0.6C

“…It is worth noting that an SFE that is too low can lead to the formation of α'-martensite and reduce ductility. In other words, the SFE of TWIP steel can be adjusted to further promote the TWIP effect by adding alloying elements [12][13][14]. It is well known that Al and Cu additions increase the SFE, thereby resulting in a decrease in the formation of deformation twins and finally decreasing the strain hardening capacity [15].…”
