Effect of heating rate on precipitation of peak-aged Al-Li (8091) alloy: A quantitative approach
Апстракт
Samples of Al-Li (8091) alloy were solution treated at 540ºC for 30 min, water-quenched and continuously heated in oil at 0.05 and 0.1ºC/min rates, from room temperature to 190ºC when the peak hardness was achieved. Having reached 190ºC at a pre-determined heating rate samples were water-quenched followed by cooling in liquid nitrogen. Precipitate identification performed by transmission electron microscopy (TEM) revealed the presence of strengthening phases formed during heating to 190ºC: δ' (Al3Li), S (Al2CuMg), and β' (Al3Zr). Applying the method of quantitative metallographic analysis (light microscopy and TEM) size, shape, density, distribution and other characteristics of precipitates were determined.
