The Embrittlement and Fracture of Steels Part Two

There are several forms of embrittlement in steel like intergranular embrittlement,temper embrittlement,embrittlement caused by overheating and burning.While cleavage fracture in steels is a common form of embrittlement,in many cases the embrittlement is intergranular (IG),i.e.it takes place along the grain boundaries,usually the former austenitic boundaries.Tempered Martensite - Harry BhadeshiaTemper Embrittlement.Whereas tempering is frequently necessary to reduce the hardness of martensite and increase toughness,the heat-treatment can lead to embrittlement when the steel contains impurities such as phosphorus,antimony,tin and sulphur.This is because these impurities tend to segregate to the prior austenite grain boundaries and Temper embrittlement is a metallurgical change that is not Jul 09,2019 What is temper embrittlement and how can it be#0183;Temper embrittlement is a metallurgical change that is not readily apparent and can be confirmed through ________.A .Metallographic examinationB .Impact testingC .MetallographyD .None of the above View Answer Answer B
