Effect of mechanical properties using cryogenic treatment on AISI EN 19 tool steels

Engineering materials fail below their yield strength due to the application of loads resulting in fracture. These fractures of materials are observed due to the grain structure or micro voids or discontinuities in grain structure. In order to improve the mechanical properties and modify the grain s...

Description
Summary:Engineering materials fail below their yield strength due to the application of loads resulting in fracture. These fractures of materials are observed due to the grain structure or micro voids or discontinuities in grain structure. In order to improve the mechanical properties and modify the grain structure, investigations have been followed with different material processing operations. In this paper AISI EN 19 tool steel mechanical properties were studied. To enhance the properties of tool steel, the material have been austenized for a period of time and quenched in water. Few of the specimens have been treated with cryogenic treatment for duration of hours and later tempered. The effect of this process has made a change in the tool steel microstructure specimens and has improved their strengths.
