Production aspects of ductility minimum emperature dmt phenomenon in as cast CuNi25 alloy

The article contains an overview of ductility minimum temperature (DMT) phenomenon in single-phase copper nickel alloy. The influence of this phenomenon on ecological and economical aspects of production has been presented. Authors characterized behavior of these materials during high temperature tensile tests and also described potential reasons of this effect. High temperature ductility tests have proven a relation between microstructure, strain rates and scale of ductility minimum temperature phenomenon.
