Metal Foam by Powder Metallurgy Routes: A Review Paper
Abstract: The aim of study is to evaluate and optimize the process parameters and several control factors of foaming because of their physical and mechanical properties such as, high stiffness, high compressive strength, and good energy absorption. Powder metallurgy is a method in which aluminum and aluminum alloy are mixed with TiH2 or other blowing agents for foam making process. Powder mixed is consolidated to obtain a high dense foam compact …

Investigation on Properties of Water and Methylene Chloride Blown Rigid Polyurethane Foam
Abstract: Physical properties are important parameters which influence the other properties and performance of rigid polyurethane foam (RPUF). Water and methylene chloride are the important ingredients of RPUF which act as blowing agents and influence the density, morphology and fire properties. RPUF samples were prepared from crude 4, 4’-diphenylmethane diisocyanate (CMDI), polyether polyol, triethylene diamine (TED), 1, 4-butane diol, polysiloxane ether, water and methylene chloride. RPUF with different densities were prepared …
