Can somebody tell me why, when we carried out stirring at 1000rpm or above, did the material's temp decrease to 577 degree C?
I had tried many time to cast Al-7Si alloys through the rapid slurry formation (RSF) process at different rpm e.g. 400, 600, 800, 1000, 1200, 1400 rpm. At low shear rate 400-800, the temperature...
