Abstract
A liquid phase sintering method was carried out in order to sinter the 13Cr-Mo-Ti steel strengthened by y-A1203 with Fe-Ti alloy powders, and the reaction of dispersoid with the alloy elements and its effect on the structure obtained were investigated.
The results obtained are as follows:
1) γ-Al2O3 added as the dispersoid has reacted with Ti existing in the Fe-Ti alloy and the matrix. As a results of this reaction, a complex oxide has been produced and the distribution of oxide particles improved.
2) Dispersion strengthening effect is also improved by satisfactory thermal stability of the complex oxide produced by above mentioned reaction and also better dispersoid/matrix bondings are obtained.
