The lattice parameters of austenite and ferrite in FeC alloys as functions of carbon concentration and temperature

Understanding the Behavior of Advanced High-Strength Steels Using Atom Probe Tomography

“…The integrated intensities of the (200) a , (211) a , (200) c , and (220) c peaks were used in the direct comparison method. [40] The carbon concentration of the RA was calculated from the lattice constant measured from the (200) c and (220) c diffraction peaks and using the following equation: [41] a c ¼ 0:…”

Lattice Constant of Iron and Austenite Including Its Supersaturation Phase of Carbon

“…They reported that the lattice constant linearly expanded with increasing temperature. Onink et al 5) also measured the lattice constant of austenite at elevated temperature using a neutron diffractometry and formulated it as the function of temperature and carbon concentration. The dependency of lattice constant on temperature and carbon concentration agreed in these investigators, and the absolute value of lattice constant did not agree each other.…”

Ab initio моделирование энергии растворения и активности углерода в ГЦК-Fe

“…При этом ис-пользовались экспериментальные значения параметров решетки, взятые из экспериментальной работы Онин-ка [27] для T = 1400 K: a = 3.667 ¦ для чистого ГЦК-Fe, a = 3.687 ¦ для системы из 32 атомов железа и рас-творенного атома углерода и a = 3.707 ¦ для системы из 32 атомов железа и двух растворенных атомов углерода.…”
