摘要：
Ball-milled Fe, Co and Cr powders have been investigated by differential scanning calorimetry to study the stored enthalpy and the origin of the enhanced specific heat in these materials. The samples were prepared of high purity powder of 40-50 mu m initial particle size and milling times up to 1 month have been applied. The results of calorimetric measurements have been correlated with structural parameters (average grain size and dislocation density) obtained by high resolution X-ray diffractometry.
