hi experts i have a question about how to do a DSC test. I have a sample (shape memory alloy) to do that test on. I want to determine the phase transformation temperatures. I have done the DSC test several times and gained results that are not favorable. in fact my alloy must not have these transformation temperatures (I'm sure about the composition of my alloy). I think the way I prepare the sample is not correct. for example during cutting the DSC specimen from the original sample, stresses may remain in it and adversely affect the transformation temperatures or maybe during removing the oxide layer mechanically this also happens. I wonder if there is any standard method to prepare the sample for DSC test to get to good results. please help.
