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.
