Cr2AlC Decomposition and Al Dissolution in Molten Copper
In Cr2AlC, Al is weakly bonded to Cr, while C is strongly covalently bonded to Cr. Due to this bonding characteristic, at high temperatures, Al atoms are dissolved and solid-solved into the copper matrix due to the stripping effect of the molten Cu metal's strong chemical affinity. Due to the dissolution of Al atoms, Cr2AlC undergoes in situ decomposition to form Cr7C3 or Cr3C2.
