Abstract To reduce the cost of manufacturing tools, which are commonly made from powder steels, high-alloy tool steel in form an ingot was cast. Conventional casting allows better use recycled materials and overall reduction material production costs. This experimental then processed a semi-solid state to remove unsuitable structure obtain desired functional properties. In case it is primarily ...

Present chemical-physical characteristics of ingot and continuous casting powders can be critically evaluated pointing out history of invention of these materials. In an original tone, pioneering nature of first developments of casting powders will be described, illustrating empirical know-how of casting powders technology, based on trial-and-error method. It will be originally emphasized that ...
