Příprava kované rychlořezné oceli s vysokým stupněm prokování a ultrajemnou strukturou pro speciální nástroje

The paper describes the problem of high-speed steel forging. To achieve wear resistence and high reability of steel tools, a high degree of forging must be ensured. High-speed steel is one of the hard-to-formable materials with a narrow forging temperature interval. Exceeding the u...

Analysis of Fractured Weldment of Hadfield Steel

This contribution is divided into two sections. The first one deals with identifying the cause of fracture in a ring, which fractured after weld surfacing. Optical and scanning electron microscopy and hardness testing were employed. Chemical composition was determined using the GDOES an...
