Abstract:

There is an increasing demand for advanced materials for aerospace and other applications, with temperature capability ranging from 1500℃ to well over 2000℃ and able to survive highly corrosive environments whilst subject to intense heat fluxes and mechanical stresses. The interaction of environmental conditions together with the requirement that dimensional stability is maintained makes the selection of suitable materials extremely challenging. This paper discusses the design, development, manufacture and testing of a new class of ceramic matrix composites based on either SiC or C fibre preforms and enriched with different ceramic powders as well as a matrix infiltrated by either microwave- or RF-heated chemical vapour infiltration (CVI). These composites will form suite of materials suitable for application in severe aerospace environments.

Shouxun Ji is currently a Lecturer at BCAST. Before rejoining Brunel in October 2010, he was a Manager at Arcadia, leading a team working on various projects to develop products and managing supply chains. Prior to that, he was the Chief Engineer of BCAST specialized in semi-solid processing of rheo-die casting, rheo-extrusion and rheo-twin roll casting. He is focusing on developing lightweight materials and structures for the automotive industry, including purpose developed aluminium and magnesium alloys with improved ductility, strength, modulus, or thermal conductivity, and the hybrid structures using different materials. He is also working on new materials for aerospace application, such as materials for explosive cords and high strength casting materials for aircraft. Meanwhile, he is in charge of all the equipment specification, planning and supply in the AMCC 1 and 2 programmes.

Abstract:

The formation, 3D morphology and growth mechanism of Al₆(Fe, Mn) phase were studied in Al-Mg-Mn-Fe alloys processed by high pressure die casting (HPDC). Thermodynamic calculation indicates that Al₆(Fe, Mn) phase in the HPDC Al-Mg-Mn-Fe alloys is a metastable phase. The experimental results confirm that Mn addition in the alloy suppresses the transformation from metastable Al₆(Fe, Mn) phase to stable Al₁₃(Fe, Mn)₄ phase under nonequilibrium solidification conditions. Energy-dispersive spectroscopy (EDS) analysis of extracted particles reveals that the average Mn/Fe atomic ratio in the Al₆(Fe, Mn) phase decreases as the Mn/Fe atomic ratio in the melt decreases. It is also found that the Al₆(Fe, Mn) phase grows to form two elongated prism morphologies: rhombic prism (equilibrium morphology, bounded by {110} and {002}), and rectangular prism (growth morphology, bounded by {002}, {200} and {020}). The primary Al₆(Fe, Mn) phase shows hollow structure and the eutectic one is in the form of fine solid particles. The growth mechanism of Al₆(Fe, Mn) phase is also elucidated according to the crystallographic rules and the morphological characteristics of Al₆(Fe, Mn) phase.
