抄録

The strain rate dependence of liquid Cu embrittlement was studied by a simulated hot tensile test. Carbon steel containing 0.1 % C showed this embrittlement at 1 323 K, just below the melting point of pure Cu. Fe-36Ni showed a very distinct embrittlement in the temperature range between 1 350 and 1 473 K. This embrittlement strongly depends on the strain rate in both 0.1C steel and 36Ni alloy. Faster strain rate than the velocity of grain boundary penetration of liquid Cu improves hot ductility and shows no embrittlement. CP Ti does not show any embrittlement.
