This paper describes the concept and implementation of a collaborative learning platform for school education over the Internet. The authors called this platform the "eTrip System," because they applied it to a school field study. Using information technologies, it supports the whole learning flow for a field trip: pre-trip learning; hands-on learning; and post-trip learning. It enables student...

Transformation induced plasticity (TRIP) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. These characteristics of TRIPsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deforma...
