Exploring the Role of Graphite in Liquid Metal Bath Formation

In summary, the conversation is about understanding the dynamics of graphite in a bath of liquid metal, and how it behaves when the bath is cooled into a solid ingot. The speaker is looking for resources or a discussion on this topic, and mentions that most transition metals readily form a stable carbide. They also suggest consulting Smithells "Metals Reference Book" for thermochemical data on carbides.

Hi guys, I'm a physicist and would appreciate some direction in helping me understand the dynamics (or chemistry) of graphite in a bath of liquid metal. Eventually the bath is cooled into a solid ingot. There are several different metals which are used (Cu, Fe, Al as well as many alloys). Any help would be greatly appreciated. I could use links to papers, textbooks, research groups, etc. Or if you really feel like getting into it, please have a discussion right here!

Thanks in advance.

I'm not exactly sure what you mean by "dynamics of graphite in a liquid metal bath". If you are asking whether graphite dissolves in liquid metal, a good guide to this is whether the metal readily forms a stable carbide or, if an alloy, one of the constituents does. Copper does not. Most, if not all, transition metals do. Smithells "Metals Reference Book" has a table of thermochemical data of carbides that serves as a guide

If you need further information, please expand a little further on what you require
 

1. What is the role of carbon in liquid metal?

Carbon plays a crucial role in the properties and behavior of liquid metals. It can affect the melting point, viscosity, and electrical conductivity of the metal, as well as its corrosion resistance and mechanical strength.

2. How does carbon get into liquid metal?

Carbon can be introduced into liquid metal through various methods, such as the addition of carbon-containing alloys or the reaction between the metal and carbon-containing gases in the atmosphere. It can also be present as an impurity in the raw materials used to make the metal.

3. Can the amount of carbon in liquid metal be controlled?

Yes, the amount of carbon in liquid metal can be controlled through precise measurements and adjustments during the production process. The composition of the raw materials and the temperature and atmosphere during melting can also affect the amount of carbon present in the metal.

4. What are the effects of too much carbon in liquid metal?

If the amount of carbon in liquid metal is too high, it can lead to a decrease in mechanical strength, increased brittleness, and reduced corrosion resistance. It can also cause issues with casting and processing of the metal.

5. How does carbon affect the properties of different types of liquid metals?

The effects of carbon on liquid metal can vary depending on the type of metal. For example, in steel, carbon can increase strength and hardness, while in copper, it can decrease strength and increase electrical conductivity. The specific properties of the metal and the amount of carbon present will determine the overall impact on its behavior.
