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

The cooling effect of perspiration as it evaporates from the skin is the result of high of water?
The cooling effect of perspiration is due to the high heat capacity of water. As sweat evaporates from the skin, it absorbs heat energy from the body in order to change from a liquid to a gas, resulting in a cooling effect.
What is the name of the cooling effect for moving air at different temperatures?
The cooling effect is called the wind chill effect. It is the increase in the rate of heat loss experienced by a body due to the combination of wind and cold temperatures.
Which property of water accounts for the cooling effect of perspiration?
The property of water that accounts for the cooling effect of perspiration is its high specific heat capacity. This means that water can absorb a lot of heat energy before its temperature increases significantly. When sweat evaporates from the skin, it takes away heat energy from the body, leading to a cooling effect.
How do you make a cooling headband?
To make a cooling headband, you can soak a bandana or fabric headband in cold water, wring out the excess water, and place it in the refrigerator or freezer for a few minutes before wearing. You can also sew pockets into the headband to insert cooling gel packs. Another option is to use specialized cooling fabrics that you can wet and wear for a cooling effect.
Can eruptions cause global cooling?
Yes, volcanic eruptions can cause global cooling by releasing ash and sulfur dioxide into the atmosphere. These particles can scatter sunlight and reduce the amount of solar radiation reaching the Earth's surface, leading to a cooling effect.
Does ozone layer has cooling effect?
Ozone does have a cooling effect. It is because of its properties.
What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
Science fair do heating and cooling effect the strength of glass?
No, heating and cooling does not effect the strength of a glass
Are there cooling mats for my PlayStation 3?
No, but laptop cooling mats (or cooling pads) can be used to the same effect.
Does alloys effect the color of metals?
Yes i sure dose ! it effects everthing
Does Diamond have cooling effect?
Diamond doesn't have any cooling effect but it is an effective heat sink since diamonds conduct heat quite easily.
How does cooling time effect rocks?
The longer the cooling time from the melted state, the larger the crystals.
Which effect does the ocean not have on the land?
Cooling land in winter
Water as ice has a cooling effect?
Yes, it is true.
What is the effect of cooling on pulse rate?
Cooling slows heart rate, thus slowing the pulse rate.
Why evaporating of water cause cooling?
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
