Abstract

Weld deposits from advanced high-strength steel constructions may suffer from severe embrittlement reactions caused by non-qualified PWHT procedures. This effect, if not detected, can lead to catastrophic brittle failure of the component. A temper embrittlement reaction in the weld deposit was detected as root cause of this effect. By qualified application of reversible temper embrittlement (RTE) treatment, characterized by a short-time heat treatment at about 600 °C, the toughness of the embrittled weld material can be significantly recovered. Basic investigations were performed to explain the embrittlement as well as the de–embrittlement effect. Examples of successful RTE application on embrittled welds are given.
