Yes, always. the temperature of the heat, time for which it is applied, cooling methods and metal itself all determine how its tensional, torsional and compressional strength will be affected (stronger or weaker, and by what factor).

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 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.
Why is metal use for power cables?
Metal will conduct the power along its length. Metal also gives the power cable strength to withstand adverse weather conditions.
Difference between post heating and pwht?
post heating : after completion of weld is not cool below to preheat or room temp. further it is heat by applying addition heating system to certain period of time and temperature to evalute hydrogen from weld metal.
Does heat reduce the tensile strength of metal?
Heating a metal decreases the tensile strength and increases ductility
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 happens to metal when cooled?
It contracts.
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.
When metal is cooled by ice what will the particles do?
The particles will contract.
What is the basic process for metal casting?
The basic process for metal casting involves heating a metal (such as iron) until it becomes molten. Then, the molten metal is poured into a metal cast which is specifically shaped to form a weapon or tool such as a sword or hammer. Once cooled, the metal cast is broken open, and the solid metal form within is cleaned and shaped to a high quality standard. After the process is complete, the product is then prepared for shipment to sell.
How do you make swords?
You can make a "toy" sword from wood by carving the edges down. To make an actual sword from metal, a block of heated metal is pounded, then cooled, then repeatedly heated and flattened again to make it into a hard, narrow strip. This provides strength to the metal. If liquid metal were simply poured into a flat form, it would not have the required toughness.
How grain size depends on the temperature of liquid metal?
It doesn't, it depends on how fast the metal was cooled.
What is a metal used when heating?
Steel iron copper alimunium are used for heating
Do alloys produce strength?
Alloys can add strength to a metal
How does strength of acid affect the time to dissolve a metal nail?
This depends not only to the reactivity o f metals; other factors are temperature, pressure, the form of metal (big piece, granules, powders).
