Heat treatments are frequently used to modify the microstructure and mechanical properties of materials according requirements their applications. Laser surface treatment (LST) has become a relevant technique due high control parameters localization involved in modification. It allows for rapid transformation near surface, resulting minimal distortion workpiece bulk. LST encompasses, turn, lase...

Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...

master moulds are used to cast copper anode moulds. these iron moulds are made of grey or nodular cast irons. according to desirable properties of ductile irons, it was expected that ductile cast iron moulds could have performed their nominal life. but in service, these moulds have not performed their nominal life and they have experienced premature failures due to warping and cracking. also gr...

The influence of mechanochemically produced modifiers on the properties cast iron at out-of-furnace modification has been studied. Short-term treatment in mechanochemical activators makes it possible to produce composite modifiers, which are wetted with melts, uniformly distributed therein and effectively crystallization processes. effect a modifier based silicon carbide chromium (as protector ...
