Non-metallic inclusions usually deteriorate mechanical properties and surface quality of steel products. Presence of non-metallic inclusions might have negative affected some of the mechanical properties of steels like ductility, toughness, anisotropy, and formability. Macroscopic method for assessing the content of non-metallic inclusions in forge...

This paper is concerned with carburization heat treatment. Standard carburization generally entails several steps: carburization of the surface layer by carbon diffusion at high temperatures, subsequent hardening and stress relief. This combination of hard surface and resistance to breakage upon impact is useful in parts such as a cam or ring gear,...

In this paper the effect of different heat treatment (recrystallization, spheroidizing and normalizing) processes on microstructure of the steel DC04 intended for deep drawing is presented. The steel is cladded with CuZn10 layers by explosive welding. Since the melting temperature of alloy CuZn10 is significantly lower (melting range 1025-1045 oC) ...

Carburizing is a very popular method of thermochemical treatment to increase the surface hardness of steel parts. It is achived by heating the steel at an austenite temperature in an environment of appropriate carbon source. Carbon sources provide the corresponding so-called a carbon potential (C potential). In the case of equilibrium state, the ca...

Application of the new materials in the automotive industry is a challenge that is placed in front of researchers of our times. The challenge is reflected in the modification of the chemical composition of steel and heat treatment in order to achieve improved mechanical properties. Steel 17-7PH is austenitic - martensitic steel with ...
