Effect of adding cobalt and iron on the resistance of β1 in Cu-Al-Mn alloys to decomposition
Alloying Cu-Al-Mn material with cobalt and iron increases the resisance of β1-phase towards decomposition.
An increase in aluminum content in Cu-Al-Mn alloy by 1% reduces the resistance of β1-phase to decomposition by about a factor of ten.
