Abstract

Abstract

The Fe-based amorphous powders with different mass fractions of 0, 5%, 10% and 15% were added to the matrix of Fe-based prealloyed powder. After the matrix sample was made by hot pressing sintering, the Rockwell hardness, the flexural strength and the wear rate were tested. For the sample without powder, its Rockwell hardness, flexural strength and wear rate are 104.6 HRB, 610 MPa and 3.3 respectively. For the sample adding 10% amorphous powder, its Rockwell hardness and flexural strength increase to 107.7 HRB and 965 MPa, which are 3.0% and 58.2% higher than the corresponding values of the original matrix respectively. The wear rate decreases to 0.9, which is 72.7% lower than the corresponding value of the original matrix. For the sample adding 15% amorphous powder, its Rockwell hardness and flexural strength increase to 110.0 HRB and 790 MPa, which are 5.2% and 29.5% higher than the corresponding values of the original matrix respectively. The wear rate decreases to 0.6, which is 81.8% lower than the corresponding value of the original matrix. Therefore, the addition of Fe-based amorphous powder can significantly improve the mechanical properties and the wear resistance of matrix samples. In addition, the DSC and the XRD tests of Fe-based amorphous powder show that at 500~700 ℃, the Fe-based amorphous powder will produce the process of crystalline phase transformation. The B element is integrated into NiSi phase to convert into NiSiB phase, and the Si element is integrated into CrFe phase to form SiCrFe phase, which can improve the matrix structure and properties.
