- Precipitate hardening is commonly used in materials science to control strength by acting on the number density, size distribution, and shape of solute precipitates in the hardened matrix. The Fe-Cu system has attracted much attention over the last several decades due to its technological importance as a model alloy for Cu steels. In spite of these efforts several aspects of its phase diagram remain unexplained. Here we use atomistic simulations to characterize the polymorphic phase diagram of Cu precipitates in body-centered cubic (BCC) Fe and establish a consistent link between their thermodynamic and mechanical properties in terms of thermal stability, shape, and strength. The size at which Cu precipitates transform from BCC to a close-packed 9R structure is found to be strongly temperature dependent, ranging from approximately 4 nm in diameter (similar to 2700 atoms) at 200 K to about 8 nm (similar to 22 800 atoms) at 700 K. These numbers are in very good agreement with the interpretation of experimental data given Monzen et al. [Philos. Mag. A 80, 711 (2000)]. The strong temperature dependence originates from the entropic stabilization of BCC Cu, which is mechanically unstable as a bulk phase. While at high temperatures the transition exhibits first-order characteristics, the hysteresis, and thus the nucleation barrier, vanish at temperatures below approximately 300 K. This behavior is explained in terms of the mutual cancellation of the energy differences between core and shell (wetting layer) regions of BCC and 9R nanoprecipitates, respectively. The proposed mechanism is not specific for the Fe-Cu system but could generally be observed in immiscible systems, whenever the minority component is unstable in the lattice structure of the host matrix. Finally, we also study the interaction of precipitates with screw dislocations as a function of both structure and orientation. The results provide a coherent picture of precipitate strength that unifies previous calculations and experimental observations.

- Aims: This study investigates whether conditions present or established in youth and adolescence among young men contribute to the differences in the risk of an early disability pension (DP) among social classes. Methods: The study is based on data from a nationwide survey of the 49,285 Swedish males born between 1949 and 1951 who were conscripted into military service between 1969 and 1970. Data on socioeconomic groups were based on information of occupation and educational level reported in the census of 1975 held by Statistics Sweden. Potential psychosocial and behavioural risk factors were linked to records from the Swedish Social Insurance Board up until 1993. The analyses were based upon those 33,609 conscripts with information on all background variables who reported an occupation and who were not granted a DP in 1975. Results : The strongest social class difference in the distribution of risk indicators was found for low ranking on the psychometric tests and for having been in a remedial class. In the univariate analyses, the highest odds ratios were noted for unskilled manual workers. In the multivariate model, with all the background variables included, the increased risk ratios for lower socioeconomic groups decreased considerably for a DP irrespective of diagnosis, and diminished for a DP with an alcohol-related diagnosis. Conclusion: It is concluded that conditions present or established in youth and adolescence are of major importance to understand the strong social class gradient in disability pensions among young men. It is suggested that the increased risks for skilled and unskilled manual workers compared with non-manual employees might be interpreted according to the concept of unfavourable life careers.
