The role of microstructure in the temper embrittlement of low alloy steels.
… of heat treatment on the susceptibility to temper embrittlement (Ductile-Brittle transition temperature and low energy fracture characteristics) of eleven experimental steels.These experimental alloys represented a range of compositions related to engineering steels and corresponded to a …

Evaluation of Temper Embrittlement in 2.25 Cr- 1 Mo Weld Metals Utilizing X-Ray Diffraction.
Temper embrittlement in low alloy steel is a phenomenon of reversible embrittlement occurring when a susceptible alloy is held in or slowly cooled through a temperature range of 1100 - 650 °F (13). Characteristics of this type of embrittlement are a reduction in notch toughness, an increase in the …

Impact fracture of embrittled stainless steels
Hydrogen embrittlement of austenitic stainless steels and temper embrittlement of a martensitic stainless steel have been studied by impact testing, metallography, and SEM fractography. New data for uncharged and hydrogen-charged specimens of Types 304L and 316L austenitic stainless steels show …

A study of the microstructural and mechanical properties of novel spring steels.
… by Pandrol from a SiMn alloy in the quenched and tempered condition. For many years low to medium carbon based spring steel has been manufactured via an oil quench temper route producing components with suitable mechanical and microstructural properties. The current problem facing the spring …

The impact toughness of iron manganese alloys.
… nickel. However, Fe-Mn alloys are susceptible to temper embrittlement through segregation of Mn, N and P to prior austenite grain boundaries. The present investigation shows that impact toughness can be improved by tempering to produce small amounts of reverted austenite into the structure. In …

Development of the small punch test platform to evaluate the embrittlement of power plant materials
… due to in-service aging mechanisms (i.e. temper embrittlement, creep, etc.) and poor engineering and maintenance practises. Mechanical, metallurgical and non-destructive techniques are used to evaluate the condition of the in-service materials in order to aid in these life assessments. The …
