摘要: Design and fabrication processes and compositions for bulk metallic glass materials. Examples of bulk metallic glasses based on the described compositions may contain a high atomic percent of titanium or iron, which is alloyed with metalloid elements and refractory metals. The compositions can be designed using theoretical calculations of the liquidus temperature to have substantial amounts of refractory metals, while still maintaining a depressed liquidus temperature. The alloying elements are molybdenum, tungsten, chromium, boron, and carbon may be used. Some of the resulting alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous alloys have increased specific strengths and corrosion resistance compared to conventional high strength steels.
