摘要：

Material Behaviour of a Cast TRIP/TWIP-Applicable CrMnNi-Based Steel up to High Strain Rates. The mechanical behaviour of a high alloyed and meta-stable cast steel alloy was examined under tensile and compressive loading in a wide range of strain rate (4.10(-4) S-1 up to 2200 S-1). The CrMnNi-based alloy showed a distinctive TRIP-effect, resulting in high strength and also excellent ductility. Additionally, mechanical twinning (TWIP-effect) was observed at temperatures above 60 degrees C up to 100 degrees C. A special focus was given to reveal the change in microstructure through mechanical loading. It was found, that there is a significant influence of higher strain rates on mechanical behaviour of the investigated alloy. Heating of the specimen is the consequence of rising strain rates, hindering the formation of alpha'-martensite and affecting the work hardening of this material strongly.
