What factors affect the Glass Transition Temperature?
cooling rate
Is superconductor diamagnetic?
Yes - it is a perfect diamagnet below its transition temperature
What is the glass transition temperature of pet plastic?
Around 70 degrees Celsius.
Does sound travel faster in cold air or in steel?
Sound travels faster in steel than in air, regardless of temperature.
Does two solids make steel?
Carbon steel is iron with some carbon (around 2-6% by weight). At room conditions both of these components are solids.
What is ductile to brittle transition temperature of steel?
It varies. Firstly, it's only present in ferrittic steels like carbon steel, not in most kinds of stainless. Secondly, it depends on the grain size of the steel microstructure, with smaller grains giving a lower transition temperature. The third factor is alloying elements. Silicone and Nickel content tends to raise transition temperature. With modern steels the transition temperature is about -60 degrees celcius. Older steels may have a transition temperature at room temperature, or, more often, at 0 or -10 degrees.
What is the impact strength value of mild steel?
it is the resistance of material to impact(sudden) loading...or..it is the impact energy absorbed per unit area.
What is the importance of impact test?
Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition. It is to determine whether the material is brittle or ductile in nature.
What is a steel strengthening transition metal?
H
What is the glass transition temperature of silk?
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
What is impact tested carbon steel?
By the ability of the material of carbon steel, its called as IMPACT tested carbon steel
What transition metal is used in many important alloys including steel?
Steel is an alloy of iron and carbon. Carbon (C) is a non-metal, and iron (Fe) is a transition metal.
Why does the temperature remain constant at the transition temperature even though heating is continued?
At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.
What is the answers of TM and tg in chemistry?
Tm is temperature of melting. Tg is glass transition temperature.
What is glass transition?
The glass transition is a second order phase transition. For materials that have a glass transition temperature, below it they are hard and brittle and above it they are softer and "rubbery".
What is the glass transition temperature of cotton?
It doesn't have
What temperature would water be if steel was put in it?
That really depends on the temperature of the water and the steel !
