摘要
高速钢与45号钢摩擦焊制造杆状刀具的环形裂纹主要有焊后冷却裂纹和淬后裂纹两种,研究了其产生的原因。
The paper discusses a kind of circular cracking on rod type cutting tools made by friction welding between high speed steel and 45~# steel. The cracking appeared as cooling cracking after welding and quenching hardening cracking. The reason for the cracking is probed, too.
