第一段压力为使非晶合金棒能够在超塑性状态下流动的力F1，施加压力的时间为T1，第二段压力为非晶合金超塑性状态结束之后所施加的力F2，施加压力的时间为T2，其中，F2>1.2×F1，T2>0.3×T1。The first stage of pressure is the force F1 that enables the amorphous alloy rod to flow in the superplastic state, the time of applying the pressure is T1, and the second stage of pressure is the force F2 applied after the superplastic state of the amorphous alloy ends. The time is T2, where F2>1.2×F1, T2>0.3×T1.
需要说明的是，通过上述的采用分段加压的方式，可以消除硬质金属或硬质合金与非晶合金之间的间隙，提高结合强度，使产品的致密度提高。第一段压力F1为使非晶合金能够在超塑性状态下流动的力，第二段压力F2为超塑性状态结束之后使复合材料的致密度提高的压力。It should be noted that, by adopting the above-mentioned method of subsection pressing, the gap between the hard metal or hard alloy and the amorphous alloy can be eliminated, the bonding strength can be improved, and the density of the product can be improved. The first stage pressure F1 is the force that enables the amorphous alloy to flow in the superplastic state, and the second stage pressure F2 is the pressure that increases the density of the composite material after the superplastic state ends.
