Description

The relatively poor microwave electrical conductivity of additive manufactured AlSi10Mg results in many applications relying on the use of post processing in the form of silver plating.  For space & satellite application, extreme thermal cycling can cause expansion of the component and the silver plating at different rates. In addition to this, extreme thermal expansion of the component can lead to changes in operating frequency. Therefore, assessment of the thermal properties of AlSi10Mg is of particular importance for it utilisation in practical applications.

This dataset constists of an overn ramp (300-450K) and a fridge ramp (300-6K). cooling_6-300K.exl contains three colums (Temperature in Kelvin, Frequency in Hz and Quality Factor) for the fridge ramp. heating.tdms is the data for the oven ramp. The file contains data tabs for five resonant frequency modes (Mode 0= TM010, Mode 1= TM110, Mode 2= TM210, Mode 3=TM020 and Mode 4=TM310) The data used in publication was Mode 0, Mode 2 and Mode 4. The data for each mode consits of two temperature measurments in celsius, time in seconds, resonant frequency in Hz, bandwidth in Hz and insersion loss in dB.
