摘要
A new electrothermal alloy containing 0.1—1.0 wt% yttrium has been developed by Prof.Li Pei andhis coworkers in Baotou Research Institute of RareEarth.This alloy is characterized by low brittleness,high strength at high temperature,good cold worka-bility,high service temperature,long lifetime and lowoxidation rate.The experts identified that its compre-hensive property had reached an advanced level incomparison with the same kind of alloy in the world.
