In this topic, it is planned to use molecular dynamics simulation methods to simulate the nanowire mechanics experiments of some face-centered cubic and body-centered cubic metal elements, hoping to obtain more specific nanowire deformation mechanisms of different elements and structures, and summarize the phases Change law. On the basis of calculation, TEM and SEM are used to characterize some samples, in order to obtain data consistent with the calculation, so as to improve the credibility of the calculation. If possible, conduct in-situ TEM mechanical tests and compare with simulated data to further verify the calculation results.

In this topic, it is planned to use molecular dynamics simulation method to simulate the nanoline mechanics experiments of some surface cubic and core cubic metal elements, hoping to obtain more specific nanoline deformation mechanisms of different elements and structures, and to summarize the law of phase change. On the basis of calculation, TEM and SEM are used to characterize some samples with a view to obtaining data consistent with the calculation, thereby enhancing the credibility of the calculation. Conditions allow for in-situ TEM mechanics testing and comparison with simulated data to further verify the results of the calculation.

In this project, we plan to use molecular dynamics simulation method to simulate the nanowire mechanical experiments of some FCC and BCC metal elements, hoping to obtain more specific deformation mechanism of nanowires with different elements and structures, and summarize the phase transition law. On the basis of calculation, some samples were characterized by TEM and SEM in order to obtain the data consistent with the calculation, so as to improve the reliability of the calculation. The in-situ TEM mechanical test was carried out under the condition, and compared with the simulation data to further verify the calculation results.<br>
