Solution For Homework Assignment 4

The fe c phase diagram is a fairly complex one but we will only consider the steel part of the diagram up to around 7 carbon.

Fe fe3c phase diagram. Of materials science and engineering 2. Mod 01 lec 23 iron carbon phase diagram duration. Ledeburite ledeburite is an eutetcic mixture of austenite and cementite in the form of alternate layers.

Alloying to produce a solid solution usually increases the tensile strength ts decreases the ductility. It provides an invaluable foundation on which to build knowledge of both carbon steels and alloy steels as well as a number of various heat treatments they are usually subjected to hardening annealing etc. Consists of two phases consists of alternate layers of ferrite and cementite in the proportion 8713 by weight.

In their simplest form steels are alloys of iron fe and carbon c. The ironiron carbide fefe3c phase diagram. The average carbon content in pearlite is 076 2.

The fe c phase diagram is a fairly complex one but we will only consider the steel part of the diagram up to around 7 carbon. Transforms to fcc gaustenite at 912 c ¾γaustenitesolid solution of c in fcc fe transforms to bcc δferrite at 1395 c is not stable below the eutectic temperature 727 c. Iron carbon phase diagram.
