“…When the hot metal liquid is poured into the mold cavity, the foam is decomposed into gaseous and liquid products due to the thermal action of the metal, and these products are expelled into the cavity through a breathable coating. There is a solid (cast wall)-liquid (AZ91D)-gas (gaseous decomposition products) three-phase interaction in the metal liquid front as same as traditional LFC [42] . However, this process also includes interactions among the liquid AZ91D, solid A356 and foam decomposition products due to the presence of the A356 inlay, which increases the complexity of metal-liquid pre-filling.…”

“…It is well known that the microstructure and properties of the castings are closely related to the filling and solidification process of liquid metal. Although there are many research works on the filling and solidification behavior in the LFC [41][42][43] , the introduction of solid inlays and the application of vibration field will make the filling and solidification behavior more complicated in the process of the bimetallic preparation. Previous studies had explored the effect of the vibration parameters on the microstructure and properties of the bimetal, but the filling and solidification process of the solid-liquid composited Al/Mg bimetal in the LFC without or with vibration has not been reported.…”

Al/Mg bimetal was prepared by lost foam solid-liquid compound casting, and the effects of mechanical vibration on the filling and solidification behavior, microstructure and performance of the bimetal were investigated. Results show that the mechanical vibration has a remarkable influence on the filling and solidification processes. It is found that after mechanical vibration, the filling rate increases and the filling rate at different times is more uniform than that without vibration. In addition, the mechanical vibration also increases the wettability between liquid AZ91D and A356 inlays. The mechanical vibration reduces the horizontal and vertical temperature gradient of the casting and makes the temperature distribution of the whole casting more uniform. Compared to the Al/Mg bimetal without vibration, the shear strength is improved by 39.76% after the mechanical vibration is applied, due to the decrease of the inclusions and Al 12 Mg 17 dendrites, and the refinement and uniform distribution of the Mg 2 Si particles in the interface of the Al/Mg bimetal.

Need of construction is increasing due to increase in population growth rate. The geopolymer concrete is eco-friendly than ordinary concrete. Current experimental investigation was conducted on ordinary and geopolymer concrete using nondestructive testing (NDT) tests like ultrasonic pulse velocity (UPV) test and rebound hammer (RH) test. Cube specimens of dimensions 150 mm × 150 mm × 150 mm are used to conduct these tests at 7, 14, and 28 days. Proportions considered for concrete are cement-fly ash-river sand (100-0-100% and 60-40-100%), cement-fly ash-robo sand (100-0-100% and 60-40-100%) whereas geopolymer concrete fly ash-metakaolin is taken in proportions of 100-0%, 60-40%, and 50-50%. Alkaline activators (sodium hydroxide and sodium silicate with molarity 12M) were used in preparing geopolymer concrete. The major objective of the current study is to obtain relation between compressive strength of concrete and UPV values.
