Development and microstructure study of closed cell LM13 alloy foams

Abstract

Metal foams need no introduction in today's industrial and research sectors. Aluminium foam based components already being used in various engineering applications or are in final stages of development. Prototypes are being made for characterization and testing purposes. The aim of present dissertation is development of closed cell LM13 piston alloy foams. The blowing agent used for foaming of aluminium alloy is CaCO3. Foams are fabricated by varying the amount of blowing agent and at different foaming temperatures. Macroscopic analyses is done by comparing the cell size and cell wall thickness of foam samples developed under different processing conditions.
