) (School of Materials Science and Engineering, Jiangsu University, Zhenjiang 212013, China) Abstract: A novel in-situ reaction system Al-Zr-O was developed. In-situ Al3Zr and Al2O3 particulates reinforced aluminum matrix composites were fabricated by the direct melt reaction technique in the Al-Zr-O system. Microstructures of the composites and crystal morphology of in-situ formed Al3Zr and Al2O3......
(TiB2/B4C) were in-situ fabricated via chemical reaction of B4C, TiO2 and graphite powders at 2 050 °C under a pressure of 35 MPa. Scanning electron microscopy (SEM) and transmission election microscopy...; in-situ reaction; toughening mechanisms......
between NiAl3 and Ni2Al3. The high temperature phases like NiAl and Ni3Al are also found at low temperature. The results indicate that the key driving force of in-situ reaction is not temperature, but the atom concentration. Key words: intermetallic compound; in-situ reaction; layered structure; back scattering photo CLC number: TG111.6 Document code: A 1 INTRODUCTION Most intermetallic......
