In situ evaluation of the low-temperature aging response of Ti–5Al–5Mo–5V–3Cr alloy as influenced by starting microstructure

The impact of starting microstructure on the isothermal behavior of β-metastable Ti–5Al–5Mo–5V–3Cr alloy during aging at 400 °C for 8 h was studied by means of in situ synchrotron X-ray diffraction. Results show that prior deformation does not accelerate phase precipitation during heating, but has an influence on secondary null precipitation during aging, and that the composition of the β matrix, which is affected by the amount of primary null...
