A fast ion can electronically excite a solid producing a track of damage, a process initially used to detect energetic particles but now used to alter materials. From the seminal paper by Fleischer et al. [Phys. Rev. 156, 353 (1967)] to the present, "Coulomb explosion" and thermal spike models have been often treated as competing models for describing ion track effects. Here molecular dynamics ...
Submitted for the MAR13 Meeting of The American Physical Society Simulation of Nanostructure and Thermal Conductivity in Binary Alloys YUSUKE KONISHI, NRI-AIST, TETSUYA FUKUSHIMA, KAZUNORI SATO, HIROSHI KATAYAMA-YOSHIDA, Graduate School of Engineering Science, Osaka University, YOSHIHIRO ASAI, NRI-AIST — Thermoelectric materials attract much attention because of concerns about energy conservati...
During quenching, hot rolled steel rings, especially those with a large outer diameter to wall thickness ratio, distort and develop undesired residual stresses. These phenomena are the result of three major mechanisms: metallurgical, mechanical and thermal. This paper presents the result of a comprehensive study on the heat treatment of rings by modeling via Finite Element Analysis. The simulat...
