decrepitation

基本解释

Hydrogen Decrepitation (HD) process has been widely used to crash NdFeB ingots in sintered NdFeB magnet industry.
烧结钕铁硼工业中，用于粗破碎钕铁硼合金铸锭的氢脆工艺的应用越来越广泛。
Compared with the grains of complete hydrogen decrepitation, the grains of selective hydrogen decrepitation are relatively larger and more uniform, but small grains are fewer.
与完全氢爆相比，选择氢爆后的晶粒较粗大，且较均匀，但细小晶粒较少。
Most ball-grinding powders, which are get from hydrogen decrepitation powder-fabricating technique are polycrystalline, which we assume will affect tropism so as to get low magnetic properties.
本文中铸带氢爆后得到的球磨粉主要是多晶体，认为影响了取向度，使其烧结体的磁性能较低。
