This research first develops a conceptual model to link relevant concepts in psychology and tourism each stage of the long-term memory (LTM) system. It combines insights from mindfulness, positive affect, quality conscious experience understand how tourists encode information; short-term working as well social identity address consolidation remembering, false memory, storytelling highlight information retrieval. Next, focus groups were conducted examine practitioners are helping encode,...
Super austenitic stainless steel (SASS) was prepared by non-consumable vacuum arc melting for the first time. The effects of rare earth (RE) elements on its solidification microstructure and segregation behavior were investigated. σ phase is main precipitation in SASS. addition RE can refine dendrite spacing. reduced secondary spacing at top (S1) 5.22 μm. as Cr, Mn, Mo have positive segregation, Ni Fe negative segregation. has trend reducing element thereby inhibiting precipitation. And...
This study examines the local residents' attitudes towards Mainland Chinese tourists visiting Hong Kong and identifies both extrinsic intrinsic factors influencing these attitudes. Results showed that residents perceive very positively due to their important role in Kong's economic development. However, it is undeniable negative dissatisfactory are also apparent. Based on findings, can be defined as "ambivalent supporters," impact of this attitude tourism development becoming influential. In...
The effects of ausforming temperature on bainite transformation kinetic and plastic deformation mechanism were evaluated by thermal simulation method warm rolling process. Results showed that entire process austempered at 300 °C was notably accelerated due to the increased nucleation sites, diminishing as well. However, would increase undercooled austenite stability, leading decrease maximum attainable volume fraction bainitic ferrite. Compared with traditional isothermal transformation,...
A multiphase microstructure comprising of different volume fractions prior martensite and ultra-fine bainite (bainitic ferrite retained austenite) was obtained by quenching to certain temperatures, followed isothermal bainitic transformation. The effect the transformation on behavior, microstructures, mechanical properties were discussed. results showed that accelerated subsequent low-temperature transformation, incubation period completion time reaction significantly shortened. This...
The effect of peak temperature (TP) on the microstructure and impact toughness welding heat-affected zone (HAZ) Q690 high-strength bridge steel was studied using a Gleeble-3500 thermal simulation testing machine. results show that inter critical (ICHAZ) ferrite bainite. fine grain (FGHAZ) coarse (CGHAZ) lath bainite (LB), martensite (LM), granular (GB), but FGHAZ finer. With increase in temperature, content LB GB decreased, LM increased, bundles gradually became coarser. size original...
The abrasion wear resistance and mechanism of super bainitic steel austempered at different temperatures time have been investigated by two-body testings, scanning electron microscopy, X-ray diffraction, transformation microscopy backscattering diffraction. results show that the is predominantly micro-ploughing abrasion, decreased with increasing isothermal temperature which attributed to hardness caused a higher retained austenite content coarsening microstructure. sample 230°C for 2 h...
