对一批裸铝线在室温下发生脆性断裂的原因进行了研究,指出主要是由于第二类氢脆造成的。材料纯净程度较差及加工硬化等也起了一定作用。对如何防止类似脆断进行了讨论。 The reasons for the brittle fracture of a group of bare aluminum wires at room temperature were studied, pointing out that it was mainly due to the second type of hydrogen embrittlement. Poor material purity and work hardening also play a role. Discussions on how to prevent similar crispness.
