ルファス合金薄帯を押出す場合も金属製の容器に入れた
後押出しても良い。In the present invention, when extruding the amorphous alloy powder, the powder may be pressed in advance to solidify it to some extent, or after being placed in a metal container or the like, extrusion may be performed. Furthermore, when extruding the amorphous alloy ribbon, it may be placed in a metal container and then extruded.
押出す際ＭｏＳ２やＣなどの潤滑剤でダイスとの潤滑を
行なうと良好な押出しが行なえる。また場合によっては
不活性ガス中で押出す。Good extrusion can be achieved by lubricating the die with a lubricant such as MoS2 or C during extrusion. In some cases, it may be extruded in an inert gas.

ある。In particular, the temperature during extrusion is 15% higher than the crystallization temperature.
When extruding at temperatures as low as 0'C, it is easy to obtain a bulk amorphous material with high density. Here, what is the crystallization temperature?
This is the temperature at which an exothermic peak due to crystallization begins to occur when measured with a DSC (differential calorimeter) at a heating rate of OK/min.
したがって、結晶化温度より低くい温度で押し出しても
結晶相が含まれる場合があるが少なくとも５０％以上が
アモルファス相であれば本発明と同一とみなすことがで
きる。Therefore, even if extruded at a temperature lower than the crystallization temperature, a crystalline phase may be included, but if at least 50% or more is an amorphous phase, it can be considered as the same as the present invention.
パイプ形状のバルクアモルファスを得る場合は中心部に
Δ１等の金属を配置し、押し出した後に中心部の金属を
引抜く。また、金属を引抜かなければアモルファスと金
属の複合材を得ることができる。When obtaining a pipe-shaped bulk amorphous, a metal such as Δ1 is placed in the center, and after extrusion, the metal in the center is pulled out. Furthermore, a composite material of amorphous and metal can be obtained without drawing out the metal.
