Heat treatment is a method used to alter the physical, and sometimes chemical properties of a material. Intercritical heat treatments in ductile iron and steel. Looks like you’ve clipped this slide to already. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc. This is a consequence of the relatively rapid precipitation of intermetallic phases (for example sigma) and nitrides from the ferrite phase at temperatures in the range 550–1050 °C.

Module 34 heat treatment of steel iv lecture 34 heat treatment of. The steel is then more homogeneous and will respond to the heat treatment in a more uniform way. CHAPTER 2 BASIC HEAT TREATMENT As Steelworkers, we are interested in the heat treat-ment of metals, because we have to know what effects the heat produced by welding or cutting has on metal. material. A complete steel component may be affected after service or heat treatment in the critical temperature range, or part of the heat affected zone of a weld may suffer the problem. It is generally preceded by a solution heat treatment. This process reduces brittleness and hardness but improves the tensile strength of Steel.
