AbstractConstitutive equations which describe the flow stress behaviour of materials during hot deformation are used to model forming processes. Since depends on both temperature and strain rate, Zener–Hollomon parameter combines these factors, is frequently shape such curves. For dynamically recover, (only) reaches a steady state value at high strains methodologies enable be modelled have previously been presented. Beyond onset dynamic recrystallisation, materials, as steels, reach peak in...

Models representing material behaviour are now an essential component of the development process for rolled products. Although models based on physical parameters being proposed, most current employ empirical equations, which assume that deformation can be characterized by strain rate, temperature and equivalent plastic strain. However, in a flat product rolling pass involves partial reversal shear strain, long section there more complex changes path sequential passes. This paper briefly...

Abstract This study responds to a gap in the literature relating resilience of people living with dementia care homes. We applied an ecopsychosocial framework resilience, theorising that sources may be personal, social and structural. Visual arts enrichment activities were examined see how they might provide opportunities for resilience. The data used this qualitative originated from aged between 70 99 years old (N = 48) four homes North East England, United Kingdom staff/carers/family...

Abstract The aim of the present paper is to monitor multiple precipitation reactions in a normal Al alloy AA 3104 and Mg- Cu-rich during isothermal annealing. Special emphasis placed on influence dislocations kinetics therefore different cold-rolling reductions are applied prior annealing treatment. Using both thermoelectric power (TEP) electrical resistivity measurements it possible split concurrent sequential reduce uncertainty about actual taking place. It found that Al2CuMg precipitates...

The benefits of volunteering for older volunteers and the organisations who host them is well-documented. impact being obliged to leave due age-related conditions, any challenges that this creates volunteer managers, are under-researched. This study explored how managers experienced point in lifecycle whether topic warranted further research. Semi-structured interviews were carried out with fourteen people, (or had been) at one three cultural heritage north-east England alongside seven from...

The microstructure of intercritically deformed lean steels is known to be rather complex, showing significant variations as a function the imposed strain path. This paper describes detailed metallographic study an C-Mn steel and generally applicable methodology for determining relevant processes from specific combinations metallurgical features.

This study focuses on the ways that people interact around contemporary craft objects. The ambiguous quality of these objects holds people’s attention and inhibits autobiographical narratives. focused relationship between perceptual language used by participants in which they interacted with analytical approach taken here begins close observation careful description single cases working towards valid generalisations rather than imposing an interpretation from outset explicitly positing a...

This paper explores how a series of contemporary art commissions displayed in heritage sites were used for emotion regulation purposes. The data was qualitative and originated from research project entitled Mapping Contemporary Art the Heritage Experience, which funded by Arts Humanities Research Council (undertaken between 2017 2019). respondents (n = 22) came four groups who visited five artworks that commissioned North East England. literature to support analysis several disciplines...

HOW CAN THE IMPLEMENTATION OF HERITAGE SKILLS WORKSHOPS HAVE A POSITIVE, SUSTAINABLE IMPACT ON INDIVIDUAL AND COMMUNITY WELLBEING?

In order to study strain path effects, hot deformation tests must be carried out utilising different combinations of compressive, tensile and shear strains. However, before the results from these can reliably interpreted, it is important carry deformations in simple tension, compression torsion as a 'baseline'. Differences mode affect deformed grain shape boundary area. The slip systems activated during, for example, will also different, this leads differences final textures substructural...
