This study hypothesized that the development of a feeling of high involvement among employees of organizations implementing the Environmental Management System （EMS） could result in the spillover phenomena of other environmentally responsible behavior in different domains such as, consumer preferences for environment-friendly products. The study also confirms the effects of environmental attitude （EA） and concrete knowledge （CK） as a mediator; acting not only as an axis to the spillover phenomenon but is also found to be the crucial factor in determining the strength of the whole spillover process.展开更多

To synthesize multi-layered Al/Cu Fe core-shell particles, Cu and Fe layers were deposited on Al powder particles by galvanic replacement and electroless plating method, respectively. The core-shell powder and sintered compacts were characterized by using X-ray diffraction(XRD), scanning electron microscopy(SEM) equipped with energy dispersive spectroscopy(EDX), pycnometer, microhardness and compression tests. The results revealed that a higher extent of interfacial reactions, due to the transformation of the deposited layer into intermetallic phases in spark plasma sintered composite, resulted in high relative density(99.26%), microhardness(165 HV0.3) and strength(572 MPa). Further, the presence of un-transformed Cu in the shell structure of hot-pressed composite resulted in the highest fracture strain(20.4%). The obtained results provide stronger implications for tailoring the microstructure of AMCs through selecting appropriate sintering paths to control mechanical properties.展开更多
