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).

Why do gallium silicon and bismuth expand on freezing?
Because all of them have orthorhombic solidification as crystalline solid.
What is the use of solidification?
solidification of metals
How is liquefied natural gas produced?
Natural gas can only be liquefied under extreme pressure.
What do you called it when liquid turns into solid?
This is called freezing, or solidification. The two terms are roughly equivalent; however, usually the term freezing is used when this occurs at a relatively low temperature such as water freezing, and solidification is used when this occurs at elevated temperatures, such as a liquid metal solidifying in a mold during a casting process.
What is a sentence for the word solidification?
When water reaches 32 degrees Fahrenheit, the solidification process begins to turn it into ice.
Which metal increases in volume during solidification?
Gallium
Why do gallium silicon and bismuth expand on freezing?
Because all of them have orthorhombic solidification as crystalline solid.
How coring of alloys during solidification be prevented?
By proper composition of metal & by slow cooling & by uniform distribution of metal
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 do oven trays expand and contract?
heat makes metal expand.
What is the use of solidification?
solidification of metals
Crater pipe in tig welding imperfection?
crater pipe is shrinkage cavity and is occurring during weld metal solidification
Why does metal expand when warm?
Because the particles
When does metal expand?
When the metal has overhotted the micrometer will overdue and drip. this is when you shut your mouth you understand!!!!!!!!!!!!!!!!!!
Will the metal ball go through the metal ring if you heat the metal ring?
yes because when you heat a metal ring it will expand
