The reasonableness of direct alloying with chrome ores is discussed with thermodynamical analysis as well as the influencing factors, such as the burden of chrome ores, basicity of slag and reductants. The results of experiments have shown that the basicity of slag should be around 1.5 and the chrome ore burden was limited up to 30% of Cr2O3 in slag. Carbon was used as reductant first and then silicon to continue for better metallurgical effect.

n this paper the status and potential of NiA1-based intermetallic alloys are presented.NIA1 is consid-ered to be next generation materials for high temperature structural applications for its properties such as high melting temperature,low density and good resistant to oxidation etc. However,low ductility at room temperature and low strength at high temperatur limit its use as engineering materials.The crystal struc- ture,defects and mechanical properties of NiA1 were studied.The room temperature ductility and high tem-perature strength are improved through alloying,microstructure control and modify the processing tech-nique.

介绍了NiAl基金属间化合物研究的现状与前景。NiAl由于具有高熔点、低密度和良好的抗氧化性等性能而被认为是下一代的高温结构材料,然而NiAl在室温时塑性低和高温时强度低限制了它作为工程材料的应用。对NiAl的晶体结构和缺陷、力学性能进行研究,采用合金化、控制显微结构和改进加工技术等方法使NiAl的室温塑性和高温强度都得到了提高。
