martensitic transformation meaning in Hindi

Examples

1. Hardening need not be due to martensitic transformation, but can also be accomplished by cold work at cryogenic temperatures.
2. There are five hardening processes : Hall-Petch strengthening, work hardening, solid solution strengthening, precipitation hardening, and martensitic transformation.
3. When the martensitic transformation temperature and the Curie temperature are the same ( based on composition ) the magnitude of the magnetic entropy change is the largest.
4. Many alloys that do not undergo martensitic transformation have been subjected to the same treatments as steels that is, cooled with no provisions for cold work.
5. "' Phase transformation crystallography "'describes the orientation relationship and interface orientation after a phase transformation ( such as martensitic transformation or precipitation ).
6. The most commonly encountered transformation of this type is the martensitic transformation which, while being the least studied, is only one subset of non-diffusional transformations.
7. He performed pioneering work in the study of martensitic transformation in crystalline materials that are of fundamental importance for the theory of phase transitions and heat treatment of steels and alloys.
8. Nitinol's unusual properties are derived from a reversible solid-state phase transformation known as a martensitic transformation, between two different martensite crystal phases, requiring of mechanical stress.
9. The martensitic transformation in steel represents the most economically significant example of this category of phase transformations but an increasing number of alternatives, such as shape memory alloys, are becoming more important as well.
10. Twin boundaries are partly responsible for shock hardening and for many of the changes that occur in cold work of metals with limited martensitic transformations : the motion of twin boundaries is responsible for the pseudoelastic and shape-memory behavior of nitinol, and their presence is partly responsible for the hardness due to quenching of steel.
