Study of iron phase transformation in aluminum alloys of the series 6XXX with short-term annealing

  • P. Yu. Bryantsev
Article

Processes of iron phase transformation in low-alloy aluminum alloys of the 6XXX series with short-term homogenizing annealing lasting less than 1 h are studied. Based on estimates of particle shape change the possibility is demonstrated of a significant reduction in homogenizing annealing duration.

Key words

alloys of the Al Mg Si system, homogenizing annealing, quantitative metallography, phase transformation 

Notes

The work was carried out within the framework of a grant from RF President for support of young scientists — science candidates MK.5561.2011.8, and with support of the program for development of NITU MISiS.
