grey cast iron because during solidification the graphite flakes expands
Bismuth and antimony are metallic elements that expand on solidification (~3-4%). These elements solidify in a monoclinic (not close-packed) structure which becomes more dense when it transforms from a solid to a liquid. A range of bismuth alloys are used for low temperature melt applications that have take advantage of the expansion to get close tolerance die castings. Gallium is a third metal element that expands during solidification (31 deg C).

What is a sentence for the word solidification?
When water reaches 32 degrees Fahrenheit, the solidification process begins to turn it into ice.
What word describes how molten metal changes into a solid?
Solidify...?
What is the use of solidification?
Solidification is the process by which a material transitions from a liquid or gaseous state to a solid state. It is commonly used in metal casting, 3D printing, and freezing of foods to create solid objects with desired shapes and properties. Solidification plays a crucial role in material processing, product manufacturing, and preservation of goods.
What happens to metal when it is heated?
The atoms that make up the metal are loosened up by the heat, therefore causing the metal structure to become more flexible.
What is the process called when particles in a metal lid expand under hot water?
This is a misconception. Particles do not expand, When they get hot they move further apart. This means that the object (the lid) gets bigger. It's just called expansion.
Which metal increases in volume during solidification?
Gallium
What is a sentence for the word solidification?
When water reaches 32 degrees Fahrenheit, the solidification process begins to turn it into ice.
What word describes how molten metal changes into a solid?
Solidify...?
Will a metal expand if it's thicker?
Yes, metal will expand when heated regardless of its thickness. Thicker pieces of metal will expand in all dimensions, but the expansion will be proportional to the increase in thickness.
How coring of alloys during solidification be prevented?
By proper composition of metal & by slow cooling & by uniform distribution of metal
Why do oven trays expand and contract?
heat makes metal expand.
Why thoes liquid grow when it change to solid?
Most liquids compress on solidification with the exception of water which due to its anomalous behaviour expands on solidification.Note also that any liquid containing water like milk will also expand on solidification.
Explain solidification of molten metal in Electrical discharge machining process?
The electric current spalls metal into the machining liquid, and the metal cools to form metal "dust" that is carried away by the liquid.

What is solidifiction?
Solidification means the process of a liquid becoming a solid, such as liquid metal cooling to become solid
Why does metal expand when warm?
Because the particles
How can a metal bar be made to expand in all directions?
Heating the metal bar evenly will cause it to expand in all directions. This is known as isotropic expansion, where the material expands uniformly in all dimensions. Heating allows the atoms in the metal to move more freely, causing the entire metal bar to expand uniformly.
