    Abstract:  鋼製の基材に焼入れを施してマルテンサイト組織からなる基材を製作し、上記基材の表面に、非晶質のNi-P合金からなる表面被覆層を形成し、上記基材に加熱処理を施すことでトルースタイト組織又はソルバイト組織に変えるとともに、前記表面被覆層をNiとNi 3 Pの共晶組織に変える。これにより成形温度において表面被覆層にクラックが発生することを防止するとともに、金型の塑性変形を防止することで、金型の形状を高い精度で維持する。

    Abstract translation: 由马氏体组织构成的基体通过淬火钢基材而形成,并且在基材的表面上形成由非晶Ni-P合金构成的表面被覆层。 然后将基底进行热处理,使得基底转变成修复体结构或山梨糖醇结构,并将表面涂层转化为Ni和Ni 3 P的共晶结构。 因此,通过防止模塑温度下的表面涂层发生裂纹,同时防止模具的塑性变形,可以高精度地保持模具的形状。

    Abstract: Design and fabrication processes and compositions for iron-based bulk metallic glass materials or amorphous steels. Examples of bulk metallic glasses based on the described compositions may contain approximately 59 to 70 atomic percent of iron, which is alloyed with approximately 10 to 20 atomic percent of metalloid elements and approximately 10 to 25 atomic percent of refractory metals. The amorphous steels may exhibit X-ray diffraction patterns as shown in Figure 1. 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 . Some of the alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous steels have increased specific strengths and corrosion resistance compared to conventional high strength steels.
