Experimental Study of the Thermal Diffusivity and Heat Capacity Concerning Some Duplex Stainless Steel

In the present work, thermal diffusivity and heat capacity measurements have been investigated in temperature range between RT and 1473 K for different duplex stainless steel supplied by Outokumpu Stainless AB, Sweden. The purpose of this study is to get a reliable thermophysical data of these alloy...
