  • Measuring and preventing decarburization in steel Paulo

    What Happens During Decarburization?What Can Go Wrong?Decarburization Test MethodsPreventing DecarburizationDecarburization occurs during the interaction between the carbon atoms in steel and the atmosphere of an endothermic atmosphere furnace. It’s essentially the opposite of carburization—carbon is drawn out of ferrous material rather than put into it.It happens when carbon content inside the furnace is not properly controlled. When the conditions aren’t right, carbon atoms in a steel part diffuse outward through its surface. Decarburiz在paulo上查看更多信息
  • Decarburization - an overview ScienceDirect Topics

    The “stainless era” is said to have begun in 1912 when austenitic Cr–Ni stainless steel was patented by the company Krupp. Soon after that also ferritic and martensitic stainless steels were developed by other inventors [1]. Acid-resistant Mo-containing stainless steels were introduced later in the 1920s.

  • Decarburization – Metallurgical Processes

    Decarburization is a surface degradation phenomenon in the forging and heat treating of steels. Decarburization may be described as a metallurgical process in which the surface of steel is depleted of carbon by heating above the lower critical temperature or by chemical action.

    The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.

    Decarburization (or decarbonization) is the process opposite to carburization, namely the reduction of carbon content.. The term is typically used in metallurgy, describing the reduction of the content of carbon in metals (usually steel).Decarburization occurs when the metal is heated to temperatures of 700 °C or above when carbon in the metal reacts with gases containing oxygen or hydrogen.
