The article deals with modeling of thermomechanical processing of high-strength steels at the Gleeble 3800 research complex, simulating thermomechanical processing with various temperature and deformation parameters of rolling and with accelerated cooling to a predetermined temperature. The identity of steel hardening processes at the Gleeble 3800 complex and specialized rolling mills, as well as the possibility of obtaining steels of unified chemical composition, are shown.

Component Parallel

A method has been formulated for the determination of thermal stresses in materials which harden in the presence of an exothermic chemical reaction. Hardening is described by the transformation of the material from an inviscid liquid-like state into an elastic solid, where intermediate states consist of a mixture of the two, in a ratio which is determined by the degree of chemical reaction. The method is illustrated in terms of an infinite slab cast between two rigid mold surfaces. It is found that the stress component normal to the slab surfaces vanishes in the residual state, so that removal of the slab from the mold leaves the remaining residual stress unchanged. On the other hand, the residual stress component parallel to the slab surfaces does not vanish. Its distribution is described as a function of the parameters of the hardening process.

Aims: This scoping review explores key strategies of creating inclusive dementia-friendly communities that support people with dementia and their informal caregiver. Background: Social exclusion is commonly reported by people with dementia. Dementia-friendly community has emerged as an idea with potential to contribute to cultivating social inclusion. Methods: This scoping review follows the Joanna Briggs Institute scoping review methodology and took place between April and September 2020. The review included a three-step search strategy: (1) identifying keywords from CINAHL and AgeLine; (2) conducting a second search using all identified keywords and index terms across selected databases (CINAHL, AgeLine, MEDLINE, PsycINFO, Web of Science, ProQuest, and Google); and (3) hand-searching the reference lists of all included articles and reports for additional studies. Results: Twenty-nine papers were included in the review. Content analysis identified strategies for creating dementia-friendly communities: (a) active involvement of people with dementia and caregivers (b) inclusive environmental design; (c) public education to reduce stigma and raise awareness; and (d) customized strategies informed by theory. Conclusion: This scoping review provides an overview of current evidence on strategies supporting dementia-friendly communities for social inclusion. Future efforts should apply implementation science theories to inform strategies for education, practice, policy and future research.

The accuracy of the simulation results of stamping processes of thin sheet material depends on the correct properties’ specification, namely stamping ability. Experiments have been carried out and the influence of the deformation speed on the hardening exponent during cold sheet metal forming was studied. It was found out, that strain changed 100 times can influence the strain grade of the hardening curve of about 10%. This regularity has been taken into consideration prior to the calculation in any CAE-software for material forming.

The process of work hardening in aluminum alloys is important from the viewpoint of formability and the prediction of the properties of highly deformed products. However the complexity of the strengthening mechanisms in these materials means that one must carefully consider the interaction of dislocations with the detailed elements of the microstructure and the related influence of the elements on dislocation accumulation and dynamic recovery. In addition, it is necessary to consider the influence of the work hardening process at various levels of plastic strain. This permits the possibility of designing microstructure for tailored plastic response, e.g. not simply designed for yield strength but also considering uniform elongation, spring-back, ductility etc. This presentation will explore the concept of identifying the various interactions which govern the evolution of the work hardening and their possible role in alloy design.
