Abstract In this paper the hot working behaviour of medium carbon duplex cast steel is studied using uniaxial compression tests over a temperature range varying from 700 ?C to 1 000 °C and at different strain rates ranging 10– 4 10 –1 s . A model based on variant dynamic materials was employed construct processing maps. These maps delineate safe unsafe domains. The domains, associated with recr...

Abstract A new open-source software, called SunMap, has been developed to obtain synoptic maps in an easy and quick way from multiple full-disc solar images. Our objective is provide a free straightforward application for heliophysicists geophysicists interested generating maps. SunMap allows comparison of structures patterns activity over various periods. Thus, the short- long-term evolution r...
