Abstract—

Molybdenum is a refractory metal, with a melting point of 2900 K. Its alloys with B and Si, obtained via powder metallurgy, have high heat resistance and have potential use in aircraft engine building. In this paper, the authors examined the possibility of using centrifugal SHS-metallurgy for the production of Mo–Si–B. To synthesize Mo–Si–B, a combination of a highly exothermic mixture (MoO₃/Al/Si/B) and a moderately exothermic mixture (Mo/Si/B) were used. In a wide range of ratios, the combustion temperature exceeds 3000°C, which makes it possible to obtain combustion products in a cast form. Studies have shown that variation in the composition of the mixture and the magnitude of the centrifugal effect allows the parameters of combustion to be controlled, along with the composition and structure of molybdenum silicoborides.

离心SHS-冶金复合材料Mo–Si–B

摘要—

钼是一种难熔金属，熔点为2900K。通过粉末冶金法获得的其与B和Si的合金具有很高的耐热性，并有可能在飞机发动机制造中使用。在本文中，作者研究了使用离心SHS冶金生产Mo–Si–B的可能性。要合成高放热混合物（MoO ₃（/ Al / Si / B）和适度放热的混合物（Mo / Si / B）。在大范围的比例下，燃烧温度超过3000℃，这使得可以获得铸型的燃烧产物成为可能。研究表明，混合物成分的变化和离心作用的大小可控制燃烧参数，以及硅硼化钼的组成和结构。
