The phase diagram indies that an iron-carbon alloy with 0.5% carbon held at 900 °C will consist of austenite, and that the same alloy held at 650 °C will consist of ferrite and cementite. Furthermore, the diagram indies that as an alloy with 0.78% carbon is slow cooled from 900 °C, it will transform to ferrite and cementite at about

2019/5/22· By imaging with as many diffracted waves as possible, it is possible to obtain an image containing the correct information of the arrangement of atoms within the unit cell. The structure image can only be observed in a thin region excited by the proportional relationship between the wave participating in imaging and the thickness of the sample.
As shown in Fig. 1, the optical path diagram of the high-resolution electron microscopy imaging process, when an electron beam with a certain wavelength (λ) is incident on a crystal with a crystal plane spacing d, the Bragg condition (2dsin θ = λ) is satisfied, A diffracted wave is generated at an angle (2θ).
2017/3/8· The findings outlined above describe the evolution of the as-deposited films from silicon carbide-like to silicon dioxide-like films as the amount of C decreases. Regarding the annealed samples up to 700°C, the IR absorption behavior remains similar to the case of their as-deposited counterparts, and it is worth mentioning that changes took place at annealing temperatures beyond 900°C [ 44
