| Abstract: | The effect of heat treatment over the range from room temperature to 500°C on the elastic properties of a bulk amorphous Pd40Cu30Ni10P20 alloy was studied. It is shown that the increase in the shear modulus under crystallization of the alloy is two-staged and that the most significant increase in the modulus occurs at the second stage. The obtained results are compared to the x-ray structural data. It is also found that the density characteristics of the as-cast material change very slightly during the transformation from the amorphous to the crystal state, with the density decreasing slightly due to crystallization. |
