我们报告了使用机械合金化合成高熔点金属-准金属间化合物。对于我们研究的所有包含铁、钛、镍、钒、钨、硅、硼和碳的 50 多种二元体系,金属间相均通过以下四种反应通道之一产生:(1)直接形成金属间化合物; (2)非晶相形成,然后退火; (3)亚稳态纳米结构形成,然后退火;或(4)形成精细混合物,然后退火。在所有这些情况下,退火都是在远低于熔点的温度下进行的。这些反应路径用 X 射线衍射结果记录。
We report on the synthesis of high melting point metal-metalloid intermetallics using mechanical alloying. For all of the over 50 binary systems containing iron, titanium, nickel, vanadium, tungsten, silicon, boron and carbon studied by us the intermetallic phases from via one of the four reaction channels: (1) direct formation of an intermetallic; (2) amorphous phase formation followed by annealing; (3) metastable nanostructure formation followed by annealing; or (4) fine mixture formation followed by annealing. In all of these cases annealing is performed at temperatures well below the melting point. These reaction paths are documented with X-ray diffractometry results.
