Mg-Pb alloys-Dendritic structure of cast alloys for SEM examination will be revealed by deep ecthing

Material: Mg-Pb alloys
Type: Micro
Method: Sublimation treatment in vacuum
Etchant (electrolyte): Temperature 70% of euectic temperature.
Procedure: Time: 5 mins at temperature, 20-30 mins cycle RT to RT, pressure: 1 exp 10 (-4) mm Hg.
Note: Dendritic structure of cast alloys for SEM examination will be revealed by deep ecthing with sublimation treatment in vacuum.
