For binary alloy cooling, the cooling temperation is a range instead of a fixed line.
During the transition (the range), equilibrium of two metals take place at each temperature (temp. decreasing), if the equilibrium finished before going to lower temperature , this is equilibrium cooling. If not, this is the one with the word "non".

What it the effect of non-equilibrium cooling on solid state phase tranformation in metals and alloys?
Non-equilibrium cooling can lead to the formation of metastable phases in metals and alloys, which may not have the same properties as equilibrium phases. This can affect the mechanical, electrical, and thermal properties of the material. Additionally, non-equilibrium cooling can result in the presence of defects and dislocations in the microstructure, influencing the material's performance under certain conditions.
Why marten site is not appear on iron iron carbide diagram?
The martenite phase does not appear on the iron-iron carbide (Fe-Fe3C) phase diagram because it is a metastable phase that forms during rapid cooling of austenite rather than being a stable equilibrium phase. The Fe-Fe3C diagram primarily represents stable phases and their transformations at equilibrium conditions, while martensite results from non-equilibrium conditions, such as quenching. Therefore, its formation and characteristics are not depicted in this equilibrium phase diagram.
Does a battery represent a system at equilibrium?
No, a battery does not represent a system at equilibrium. A battery operates by creating a potential difference between its terminals through chemical reactions, which is a non-equilibrium process as it involves the flow of electrons from one terminal to the other.
What is a non example of equilibrium?
When you have one or more things going wrong in a system then the system can't function properly. An example for your non-example would be a plant that does not get enough water, the cells become dehydrated and begin to lose shape, move out of equilibrium and eventually die.
What is the difference between non spontaneously and spontaneously?
Non-spontaneous processes require intervention or energy input to occur, while spontaneous processes occur on their own without needing external help. Spontaneous processes tend to move towards equilibrium, while non-spontaneous processes move away from equilibrium.

What is the non equilibrium model?
The non equilibrium model says that communities are constantly changing after being affected by disturbances.
What does not happen to a non moving object in equilibrium?
A non-moving object in equilibrium does not accelerate or change velocity. It remains stationary and experiences no net force acting on it.
If a solid object radiates more energy than it absorbs, its?
Cooling down and as such not in thermal equilibrium.
What phenomenon is exemplified by a cup of hot tea cooling over time?
The phenomenon exemplified by a cup of hot tea cooling over time is called thermal equilibrium, where the tea and its surroundings reach a balance in temperature.
How an objects be motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
How can an object motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
Can one force by itself create equilibrium?
No. For equilibrium, the SUM OF ALL FORCES acting on an object must be zero, and that is not possible with a single (non-zero) force.Note: For equilibrium, the sum of all torques on an object must ALSO be zero.
Why martensite is non equilibrium phase?
Martensite is considered a non-equilibrium phase because it forms rapidly during the quenching process, bypassing the slow diffusion-based transformations typical of equilibrium phases. Its formation involves a shear mechanism that occurs at low temperatures, resulting in a unique crystal structure that does not correspond to the equilibrium phase diagram. This rapid transformation does not allow for the atomic rearrangements required for equilibrium, leading to its metastable nature. Consequently, martensite possesses distinct mechanical properties compared to equilibrium phases like pearlite or bainite.
What is a peltier?
a peltier is a non-moving, quiet heating and cooling tool
Does a battery represent a system at equilibrium?
No, a battery does not represent a system at equilibrium. A battery operates by creating a potential difference between its terminals through chemical reactions, which is a non-equilibrium process as it involves the flow of electrons from one terminal to the other.
Which factor does not take a population out of Hardy-Weinberg equilibrium?
Mutation is the factor that does not take a population out of Hardy-Weinberg equilibrium. The other factors that can disrupt equilibrium are natural selection, genetic drift, gene flow, and non-random mating.
