Damage evolution and anisotropy in freeze cast metal/ceramic composites: An in-situ SEM analysis

INTRODUCTION Innovative metal/ceramic composites produced by melt infiltration of innovative ceramic preforms prepared by a freeze casting technique are examined in this study. These composites exhibit a characteristic hierarchical structure: On a mesoscopic length scale, lamellar domains with sizes up to several millimetres are observed (Fig. 1). The aim of the present study is to analyze the ...

Fabrication of Ti3SiC‌‌2-SiC max phase composites via in-situ and ex-situ synthesis

Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...

Wear of ceramic particle-reinforced metal-matrix composites

Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...
