Creep: The phenomenon of metal which allows it to deform continuously at slow rate without any further increase in stress is known as creep.
Fatigue: It is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading.
Resilience: resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading.
Plasticity: Ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behavior, and those causing failure of the material, or rupture

The Phenomenon of Metal Deformation: Creep
Introduction:
Metal is a widely used material in various industries. However, metal structures are exposed to different environmental conditions, including high temperature and stress, which affect their properties. One of the phenomena that affect metal properties is creep.
Definition of Creep:
Creep can be defined as the phenomenon of metal deformation that occurs continuously at a slow rate without any further increase in stress. Creep occurs at high temperatures and under high stresses. Creep can cause failure of metal structures, especially in applications where the metal is exposed to prolonged stresses and high temperatures.
Mechanism of Creep:
Creep occurs due to the movement of dislocations in the crystal lattice structure of metals. The movement of dislocations causes the metal to deform. The rate of deformation is slow initially but increases as time passes. Creep can be classified into three types:
Factors Affecting Creep:
Several factors affect the creep behavior of metals. These include:
Conclusion:
Creep is a phenomenon that affects the properties of metals. Creep occurs at high temperatures and under high stresses. The movement of dislocations in the crystal lattice structure of metals causes creep. Creep can cause failure of metal structures, especially in applications where the metal is exposed to prolonged stresses and high temperatures. Several factors affect the creep behavior of metals, including temperature, stress, time, and chemical environment.

Mechanism of Creep:
Creep occurs due to the movement of dislocations in the crystal lattice structure of metals. The movement of dislocations causes the metal to deform. The rate of deformation is slow initially but increases as time passes. Creep can be classified into three types:
- Primary Creep: This is the initial stage of creep where deformation occurs at an increasing rate.
- Secondary Creep: In this stage, the rate of deformation becomes constant, and the metal deforms at a steady rate.
- Tertiary Creep: In this stage, the rate of deformation increases until failure occurs.
Factors Affecting Creep:
Several factors affect the creep behavior of metals. These include:
- Temperature: Creep occurs at high temperatures, and the rate of creep increases with increasing temperature.
- Stress: Creep occurs under high stresses, and the rate of creep increases with increasing stress.
- Time: Creep occurs over time, and the rate of creep increases with increasing time.
- Chemical Environment: The chemical environment can affect the creep behavior of metals.

Creep is a phenomenon that affects the properties of metals. Creep occurs at high temperatures and under high stresses.
