This study is concerned with the effect of post welding heat treatment(PWHT)on the microstructure and properties at the intercritical reheated coarse-grained heat-affected zone(IRCGHAZ)of WB36 steel, and investigated whether the PWHT could reduce IRCGHAZ embrittlement.

The embrittlement in 1Cr21Ni5Ti duplex stainles s steel with medium titanium and aluminum content, the temperature range in whic h the toughness is sharply deteriorated has been determined and effect of soluti on temperature has been researched.

The study wanted to solve the embrittlement problem in copper alloy due to bismuth in drinking water pipe,The result showed that the embrittlement of copper alloy can be completely avoided when Sn and P were added,A proportion of Cu-Bi 1 Sn 3 Zn 6 P 0.
