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?
Basically there are two types of effects that may happen during this non-equilibrium cooling. 1. Micro-segregation -result in "hot shortness" which means the material will melt below the temperature of equilibrium solids. -this can be fixed by homogenization heat treatment, heat and hold material to allow diffusion to even out the composition gradients. 2. Macro-segregation -composition gradients on scale of part because some locations solidify before other location in part. -this situation can only be removed by mechanical mixing, in other words hot work or cold work Hope this helps
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.
When the net force is zero the forces acting on an object are?
They are either non-existent or else balanced.
What are the conditions of equilibrium when a number of parallel forces are acting on a body can a moving body be in equilibrium explain?
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
What is the non equilibrium model?
The non equilibrium model says that communities are constantly changing after being affected by disturbances.

If a solid object radiates more energy than it absorbs, its?
Cooling down and as such not in thermal equilibrium.
What does not happen to a non moving object in equilibrium?
it does not accelerate
What is the difference between rest and equilibrium?
Velocity of body and acceleration of body is zero implies body is at rest Acceleration of body is zero implies it is in a state of equilibrium Body in equilibrium can have non zero velocity
Which is not a characteristic of chemical equilibrium?
The ONLY characteristics of an equilibrium are:sort of reactants and products involvedconcentration of all components in the continuous phasetemperatureThe others are non-characteristic
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.
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.

What is a peltier?
a peltier is a non-moving, quiet heating and cooling tool
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.
