X-RAY phase analysis (XPA) of a cold-hardening mixture (CHM) and the effect of the mixture properties on the casting

The objectives of this type of research are as follows: identifying the phase composition of the samples under study; assessing the effect of the composition on the mechanical properties of the samples. Prior to the study by the XPA, the authors obtained 9 samples of different compositions to select the optimal composition of cold-hardening mixture (CHM). The method of X-ray phase analysis was selected for the phase composition of the CHM samples. After examining the samples using XPA analysis, molds were made from CHM (resin+clay) according to the composition of sample No. 3. To evaluate the quality of the castings, there was measured roughness.
