Effect of cooling rate and Y element on the microstructure of rapidly solidified TiAl alloys

Influence of cooling rate on microstructure formation during rapid solidification of binary TiAl alloys

“…Some attempts on the AM of titanium aluminide alloys have been reported recently [4][5][6]. While many experimental data are available regarding the phase evolution during solid state heat treatments and subsequent quenching [1,[7][8][9][10], comparably little is known about microstructure formation during rapid solidification [11][12][13][14]. The Ti-Al system is well studied in the solid state up to cooling rates of 400 K s À1 [7,8].…”

Thermodynamic modeling of the Ti–Al–Cr ternary system

“…␥-TiAl based alloys are considered as the candidate materials for elevated temperature applications, engineering materials in the aviation and automotive industry, for their numerous advantages such as low density, good oxidation resistance, and attractive high temperature property, they have been widely studied in the latest years [1][2][3][4][5][6][7][8][9]. The studies of structure and some properties of Ti-Cr alloys and the formation of nanocomposites containing Al and TiAl 3 in Ti-Al alloys are also reported in recent years [10][11][12].…”

Effect of cooling rates on solidification and microstructure of rapidly solidified Mg57Zn37Y6 quasicrystal alloy

“…Research on the difference of microstructure and solidification process between the traditional solidified; however, the relationship between different cooling rates and the growth mechanism of I-phase in rapidly solidified Mg-Zn-Y alloy has only rarely studied. Liu et al 17 have carried on the study of icosahedral phase in a rapidly solidified Al-Fe-Ce alloy under different cooling rates, providing a detailed and systemic work.…”
