Microstructure and Mechanical Properties of the Cold-Rolled Al?Mn and Al?Mn?Sc?Zr Alloys

Popis výsledku v původním jazyce

The conference paper reports results of a study aimed at understanding precipitation processes of the binary Al?Mn and quaternary Al?Mn?Sc?Zr alloy. The alloys were investigated in the mould-cast state and coldrolled state. The alloys were studied duringstep-by-step quasilinear annealing from 200 °C up to 600 °C with heating rate 100 K/h followed by subsequent isothermal annealing at 600 °C/4 h. The effect of the pseu dohomogenization heat treatment (610 °C/18 h) on mech anical properties of the alloysduring isothermal annealing at 300, 400 and 500 °C was also investiga ted. Precipitation reactions were studied by electrical resistometry and (micro)hardness measurements. The microstructure development was investigated by transmission, scanning electron microscopy and electron diffraction examinations. The hardening effect is due to fine, coherent, uniformly distributed Al3Sc and/or Al3(Sc,Zr) particles. The distinct changes in resistivity of the cold-rolled alloys at temperature abov
