I am using Al2O3(gamma) as the material; is it required to use piecewise function in material section to consider the variation with temperature if I have already declared the property values in the parameters section.

Piecewise fuction is used to define time dependant variable at the boundary. Global --> Definitions --> Functions. Remember to add the unit for the argument and the function.

That is correct....if you have varying material properties...either with time or with temperature, you can use any suitable function from the global definitions to define this variation...but you should define it again in the definition section of the physic.
