Effect of Ti2AlC particles on the microstructure and elevated-temperature-deformation properties of gama-TiAl alloys

Original language description

The gama-TiAl intermetallics with and without amount fractions x = 0.3 % of yttrium and with different carbon amount fractions ranging from 0.9 % to 1.6 % were prepared by vacuum-induction melting in a graphite crucible. Different amounts of carbon wereobtained by varying the time of melting. The resulting samples had large rod-like carbides with volume fractions 0.6 % to 3.7 % Ti2AlC in the lamellar matrix consisting of the alternating lamellas of gama-TiAl and alfa2-Ti3Al phases. It was found that the grain size of the matrix decreases with the increasing volume fraction of Ti2AlC carbides from 430 ?m to 35 ?m. In addition, finer carbides with a similar composition were observed. Their size was below 1 ?m and they appear mainly at the grain boundaries and also inside the lamellar grains. Compression testing revealed that all the samples had a relatively high yield strength at elevated temperature, from 917 MPa to 623 MPa at 600 °C and from 608 MPa to 547 MPa at 800 °C, but the best
