Impact transition temperature
WitrynaSteel is the most commonly used metal that shows this behaviour. For some steels the transition temperature can be around 0°C, and in winter the temperature in some parts of the world can be below this. As a result, some steel structures are … WitrynaThe glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an …
