WebSep 8, 2013 · The first step starts with holding molten metal slightly above its liquidus temperature to reach a homogenous temperature gradient. The second step is to insert a cool rod (normally made of graphite) into the melt to stir and rapidly cool the metal for a period until it reaches a temperature that is slightly below its liquidus temperature (i.e., to … WebAnswer (1 of 2): First, get the concept that steady state does not mean temperature gradient or heat transfer to be zero or thermal equilibrium to be established. It simply means temperature is invariant with time. Temperature gradient may/may not be present, based on the boundary conditions. Fo...

Cold-room simulation tests showed crystal growth to be an increasing function of the temperature-gradient modulus with a lower limit of around 0.25 deg/cm. This growth also proved to be a function of …
WebSteady two-dimensional heat conduction takes place in the body shown in the figure below. The normal temperature gradients over surfaces P and Q can be considered to be uniform. The temperature gradient ∂ T ∂ x at surface Q is equal to 10 K/m. Surfaces P and Q are maintained at constant temperatures as shown in the figure.
