Iron Carbon Ttt Diagram

TTT diagram is a plot of temperature versus the logarithm of time for a steel alloy of The complete isothermal transformation diagram for an iron-carbon alloy.

Imagine, for example, some pure iron that was kept at a temperature of oC ( .. Here is the “official” isothermal TTT diagram for eutectoid carbon steel.

This presentation is made to give an idea about iron carbon diagram, TTT diagram and comprehensive detail about HEAT treatment. The Iron–Iron Carbide (Fe–Fe. 3 Fe.

3. C (iron carbide or cementite).

• This intermetallic compound is . The TTT diagrams are for the isothermal (constant T ).

It is important to note that there is not a single TTT or CCT diagram like the Iron- Carbon diagram. Different steels have different TTT and CCT diagrams. So the.TTT diagrams are time temperature transformation or isothermal transformation diagrams.

CCT are continuous cooling transformation diagrams. Difference between TTT and CCT diagrams: The essential difference between both the diagrams is the method.

The iron-carbon diagram provides a solid base on which to build the knowledge of both plain carbon and alloy steels.

There are some important metallurgical phases and micro constituents in thr iron carbon system. At the low-carbon end is the ferrite (?-iron) and austenite (?-iron).

This latest version of the Iron Carbon Diagram is multi-dimensional. The crystal and grain structures in steels and cast irons are easier to understand with the use of colorful graphics combined with high and low magnification photo-micrographs of four carbon steel alloys, and two popular types of cast iron.
