Using format to convert decimal to HH:mm:ss really slow

I have a dax query from an SSAS cube. This takes an average of the time of day from a time dimension. I have tried a couple of measures but I am getting terrible performance trying to convert the average which is a decimal number to HH:mm:ss using format? I have this query below for an SSRS report. the Measures in the cube are decimal for average time of day 0 to 1. The query returns in under a second but if I add the bottom 2 measures that format the time as HH:mm:ss it never finishes? Is this a limitation of dax? I can create the time format in SSRS but I thought I could do this in dax.
