The sound actually emanates from breaking atomic bonds, and the subsequent rearrangement of the crystalline matrix within grains. This change occurs so quickly, that the material produces a pressure wave (sound wave) that you can hear as a popping sound.
Pretty cool, huh!?

What else can I help you with?
What causes a broken or fractured camshaft?
Lack of lubrication or defect in the metal.
What causes you to burn a hole in the metal during arc welding?
Either too much amperage, travel speed too slow, or electrode too large for the metal thickness.
How do you reduce the sound of rain on a metal roof?
Yes, to dampen the sound, before installing this metal roof, get a layer of insulation for it installed, which both reduces the sound of rain on the roof and causes them to be highly energy efficient.
What causes the oxide scale on metal during heat treatment or annealing?
chemical reaction between the oygen atoms and the carbon atoms
What does welded mean?
It's "ultrasonic weld," rather than "sound weld." Sounds more "engineering-ish," anyway. This is done by clamping two objects together - usually plastic ones, but thin metal can also be ultrasonically welded - and directing a high-power beam of ultrasonic energy at the mating point. The beam causes heat, which makes the two materials in the joint melt. When they cool down, they're fused together.
What sound does a metal spoon make?
A metal spoon typically makes a clinking or tinkling sound when it hits a hard surface like glass or ceramic.
What causes a 91 corolla to sound like metal on metal when turning the key?
That sounds like the starter isn't hitting the flywheel like it suppose to!
What causes metal on metal when it comes to brake pads?
When metal rubs against metal, it means the pad on your brake pad is wearing down. This can be extremely dangerous. If you notice any kind of unusual sounds, get your car checked immediately.
Why do water heaters make noise?
Water heaters can make noise due to the expansion and contraction of metal parts as they heat up and cool down, as well as the buildup of sediment in the tank that can cause popping or rumbling sounds.
What causes a car is make loose metal sounds underneath when driving slow?
I drive a 96 mustang,and was told that the 1990-2000 model's body is made from sheet metal and on bumps,or a dirt road it will make rattling sounds. Your exhaust pipe is another explanation if it is loose.
Oxygen causes metal to?
oxygen causes metal to rust oxidate
Are sounds produced when matter cools?
Yes, sounds can be produced when matter cools. This is often due to the contraction of the material as it loses heat, which can create stress and cause vibrations that generate sound waves. An example of this is the popping or cracking noises heard when objects like metal or wood cool down.
What is a Metal popping noise in Dodge Caravan?
Could be one of a number of things, as it could be in any vehicle.
Can Brandon Mcdowell play the tronbone?
he sounds like metal hiting metal
Why does your water tank make clicking noise?
it is were it turns on the heat to warm it upThe coefficient of expansion per degree per inch causes the metal to expand and contract making the sounds
What causes you to taste metal?
It means you can taste metal :P
Which metal reacts with acids but sounds as if you're washing your hands?
Zinc is the metal that reacts with acids and sounds like you're washing your hands (zinccing).
