What else can I help you with?
Does heat reduce the tensile strength of metal?
Heating a metal decreases the tensile strength and increases ductility
What does porosity in a weld means?
Porosity in welding is a result of dissolved gases or gases released during the welding process, being trapped in the metal when there is insufficient time to escape prior to solidification. If in the shape of rounded holes, the gas is called spherical porosity or just porosity. However, if elongated the terminology is wormholes or piping. Causes of porosity are;excessively long or short arc lengthwelding current too highinsufficient or moist shielding gastravel speed to fastbase metal covered with oil, grease, moisture etc.wet, unclean or damaged electrodes.
What is metal grain direction?
Metal Grain Direction is similar to Wood Grain Direction. It is the direction in which the metal was produced, so when you look at it under a magnifying glass and see lines, that is the direction in which the metal was made in the factory.
What is a metal rope called?
A metal rope is also called a wire rope.
What is the value of Youngs modulus for the metal?
Metal is not a specific material, how is this ever going to be answered?!
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
A heated metal block volume decreases or increases?
It decreases
How coring of alloys during solidification be prevented?
By proper composition of metal & by slow cooling & by uniform distribution of metal
Crater pipe in tig welding imperfection?
crater pipe is shrinkage cavity and is occurring during weld metal solidification
What is a sentence for the word solidification?
When water reaches 32 degrees Fahrenheit, the solidification process begins to turn it into ice.
Will air bubbles affect the volume when measuring the volume of a metal.?
Air bubbles would make the volume you read in the measuring cylinder increase from the actual volume of theliquid. so when you add in the metal, there would be an increase in the volume of the metal than it really is. the mass of the metal cannot be affected by air bubble because this is the amount of matter in the metal. This increase in volume causes the density of the metal to reduce from its original value. since mass is constant, density is inversely proportional to volume. As volume increases, density decreases.hope that was helpful.
What word describes how molten metal changes into a solid?
Solidify...?
Why does casting shrink in casting process?
when the metal transition occurs from hot molten state to cold state then its volume get reduce by the evulutaion of heat due to metal solidification and it shrins so its remedy is that fill the molten metal slowly & properly & fill it upto sprue so that when it shrinks the molten metal from sprue move down & fill the casting properly
What happens when hot metal objects cool?
When hot metal objects cool down, they lose heat to the surrounding environment, causing them to contract and reduce in temperature. As the metal cools, its atoms slow down and move closer together, resulting in a decrease in volume and the solidification of the material. This process can lead to changes in the metal's physical and mechanical properties, such as increased hardness and brittleness.
When heating metal will volume and mass change?
When heating metal, its volume typically expands due to thermal expansion, which causes the atoms in the metal to vibrate more and spread out. The mass of the metal will not change during heating unless there is a chemical reaction taking place, such as oxidation.
Is molten metal solidifies exothermic or endothermic?
The solidification of molten metal is an exothermic process. During this phase change, the metal releases heat as it transitions from a liquid to a solid state. This release of heat occurs because the molecules in the liquid metal lose energy and arrange themselves into a more stable solid structure.
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.
