Effects of Component Layer Thickness on Properties of TC4/Al3Ti Microlaminated Composites
TC4/Al3Ti micro-laminated composites were prepared by high vacuum hot pressing taking TC4 foil and pure Al foil as raw materials,and the influence of component layer thickness on the microstructure and properties of the composites was investigated.The microstructure,crack fractures were analyzed by metallographic microscopy,X-ray diffractometer,scanning electron microscopy,and field emission electron probes.The results indicate that with the constant thickness and volume fraction of Al3Ti in the specimen,the smaller the component layer thickness,the better the mechanical properties.When the number of laminated layers is 55,the component layer thickness is the minimum,and the performance is optimal,where the flexural strength is 970 MPa,the compressive strength perpendicular to the layer is 1 307 MPa,and that parallel to the layer is 1 206 MPa.
