What is the difference between full annealing and isothermal annealing?
Full annealing process consists of three steps. First step is heating the steel component to above upper critical temperature by 30 to 50 deg c, after suffciant soaking time parts will be cooled very slowly in the furnace. Where as for ISo Thermal annealing parts will be heated above upper critical temperature by 30 to 50 deg c, after suffciant soaking time parts will be transfered to intermediate temprature( Below the lower critical temperature) and allow to equalise the temperature then cool in air to Room temperature
Lower part has temperatures -50 degress upper temperature are 0 degress?
The temperature range is from -50 to 0 degrees, where -50 degrees is the lower limit and 0 degrees is the upper limit. The temperature is in the negatives and ranges from extremely cold to freezing.
What is the lower fixed point and upper fixed point of clinical thermometer?
The lower fixed point of a clinical thermometer is the temperature of the ice point (0°C) and the upper fixed point is the temperature of the steam point (100°C at standard atmospheric pressure). These fixed points are used to calibrate the thermometer for accurate temperature measurements.
What is the upper fixed point and the lower fixed point in a clinical thermometers?
The upper fixed point in a clinical thermometer is typically the temperature of a healthy human body (e.g., 37 degrees Celsius). The lower fixed point is usually the temperature of melting ice (e.g., 0 degrees Celsius). These fixed points help calibrate the thermometer for accurate temperature measurements.
Will temperature be higher or lower in a mountain?
Temperature tends to decrease as elevation increases in mountains. This is due to a combination of factors, including the thinner air at higher altitudes which can't trap heat as effectively, as well as the cooler air that flows down the slopes from the upper regions.
What is intercritical annealing?
Intercritical annealing is where the metal is heated to between its lower and upper critical temperature point to allow partial transformation of the matrix into austenite followed by slow cooling or holding below the lower critical temperature point.
What do you mean by upper critical temperature of metal?
The upper critical temperature of a metal is the temperature at which the metal undergoes a phase transformation from a solid to a liquid. This temperature is specific to each metal and varies depending on its composition.
What is the Difference between the Upper and lower yield stress in mild steel?
Lower YS is that point at which the steel flows elastically and failure takes place at upper YS.
What are the critical temperatures of iron -carbon equilibrium diagram?
At the time I'm writing this answer, I'm astudent of BSc Metallurgical & Materials Engineering and I've had a brief study of Iron-Carbon diagram recently. I hope my answer helps. The Lower Critical Temperature is 1333o F. The Upper Critical Temperature is 2066o F.
Is the upper stratosphere is cooler than the lower stratosphere?
Yes, the upper stratosphere is cooler than the lower stratosphere. This is because the absorption of ultraviolet radiation by ozone in the upper stratosphere creates a temperature inversion, where the temperature increases with altitude.

What are three differences between the upper and lower mantle?
Temperature: The upper mantle is cooler than the lower mantle. Composition: The upper mantle is more silicate-rich and less dense compared to the lower mantle. Physical properties: The upper mantle is more rigid and brittle, while the lower mantle is more ductile and capable of flow.
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
Is the upper stratosphere colder then the lower stratosphere?
Yes, the upper stratosphere is colder than the lower stratosphere. This is because the stratosphere is heated from below by the Earth's surface, so as you move higher in the atmosphere, the temperature decreases. The temperature inversion between the lower and upper stratosphere is due to the absorption of solar radiation by ozone in the upper stratosphere.
Lower part has temperatures -50 degress upper temperature are 0 degress?
The temperature range is from -50 to 0 degrees, where -50 degrees is the lower limit and 0 degrees is the upper limit. The temperature is in the negatives and ranges from extremely cold to freezing.
What is the contents of the mantle?
The mantle is primarily composed of solid rock that is rich in silicate minerals. It is divided into the upper mantle and the lower mantle, with the upper mantle being more rigid and the lower mantle exhibiting more plastic behavior due to higher pressure and temperature. The mantle is responsible for convection currents that drive plate tectonics and is a critical component of Earth's structure.
