What else can I help you with?
How would you describe a metal that has a yield strength and tensile strength that are the same?
Brittle
What metal is used in central heating radiators?
aluminum and copper
What is cheaper cold working or heat treating a metal?
Cold working is generally cheaper than heat treating because it involves shaping the metal at room temperature without the need for energy-intensive heating processes. While cold working can increase the strength of the metal through deformation, it may also lead to increased brittleness. Heat treating, on the other hand, involves significant energy costs and specialized equipment to alter the metal's properties through controlled heating and cooling. Overall, the cost-effectiveness depends on the specific application and desired material properties.
What are the materials used to make an Air Conditioner today?
it is made up of iron, aluminum, metal coils on the inside, where air is cooled, and lastly it is made up of sheet metal.
What type of metal is central heating pipes made out of?
Central heating pipes are commonly made from copper, which is favored for its excellent thermal conductivity and resistance to corrosion. Alternatively, they can also be made from PEX (cross-linked polyethylene), a flexible plastic that resists scaling and corrosion. In some systems, galvanized steel or stainless steel may be used for added strength and durability. Each material has its advantages depending on the specific heating system and installation requirements.
How does heating or cooling affect metal?
Heating metal can cause it to expand, increasing its volume and potentially altering its shape and strength. Cooling metal can cause it to contract, reducing its volume and potentially making it more brittle. Rapid heating or cooling can also lead to thermal stress and distortions in the metal.
Does heat reduce the tensile strength of metal?
Heating a metal decreases the tensile strength and increases ductility
How does the process of tempering and hardening affect the overall strength and durability of metal components?
Tempering and hardening are heat treatment processes that improve the strength and durability of metal components. Tempering involves heating and then cooling the metal to reduce its hardness and increase its toughness. This helps prevent the metal from becoming too brittle. Hardening, on the other hand, involves heating the metal to a high temperature and then rapidly cooling it to increase its hardness and strength. Overall, tempering and hardening work together to create a balance between hardness and toughness in metal components, making them stronger and more durable.
How does super-heating an alloy change it?
It melts the metal, but this does not change the alloy. Heating may mix metals into an alloy. Structurally, heating the alloy will improve strength.
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
What is the scientific term for heating metal and then rapidly cooling?
The scientific term for heating metal and then rapidly cooling it is "quenching." This process helps to alter the metal's physical properties, such as hardness and strength, by inducing a rapid transformation within its atomic structure.
How you can get the metal lid in the jar should you heat it or cool it?
cool it. When molecules are cooled they compress.
What happens to metal when cooled?
It contracts.
Which property of a block remains constant when the metal is heated?
Mass
Why does metal get stronger with heat?
Heating metal can cause the atoms to vibrate more rapidly, making it harder for dislocations to move through the crystal structure. This leads to an increase in strength. Additionally, the heat can also help to relieve internal stresses in the metal, which can further improve its strength.
I want to know the definition of metallurgic dislocations?
Metallurgic dislocations are defects or irregularities within the crystal structure of a metal. These dislocations can affect the physical properties of the metal, such as yield strength.
How grain size depends on the temperature of liquid metal?
It doesn't, it depends on how fast the metal was cooled.
