摘要

研究了添加Ti的Co3O4/Cr2O3/WO3/MoO3/C/Al混合物在人工重力作用下的燃烧规律。在大于40 g的离心加速度下，燃烧产物为目标CoTiCrWMoCAl合金(下)和Al2O3渣(上)的两层钢锭。添加量的变化(可达17 wt %)影响了铸态CoTiCrWMoCAl合金的成分和组织。采用XRD、SEM和EDS对shs合金进行了表征。采用含Ti含量为5%的CoCrWMoCAl合金，采用真空感应熔炼、惰性气体溅射法制备粉末。结果表明，粉末及其前驱体的化学成分相同。

Influence of Ti on the Structure and Phase Composition of CoCrTiWMoCAl Alloys Prepared by Centrifugal SHS

Regularities of combustion of Co₃O₄/Cr₂O₃/WO₃/MoO₃/C/Al mixtures with additive of Ti under the action of artificial gravity were studied. At the centrifugal acceleration of more than 40 g, combustion products were obtained as two-layer ingots of target CoTiCrWMoCAl alloy (lower) and Al₂O₃ slag (upper). Variation in the amount of additive (up to 17 wt %) affected the composition and structure of cast CoTiCrWMoCAl alloy. SHS-produced alloys were characterized by XRD, SEM, and EDS. CoCrWMoCAl alloy containing 5% Ti was used for preparing powder by vacuum induction melting followed by inert gas sputtering. It was shown that the chemical compositions of powder and its precursor are the same.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
