Most common examples are blue brittleness,hydrogen embrittlement and temper brittleness.While such phenomena refer to changes occurring within the metal structure,this definition can be extended to embrittlement resulting from changes generated by the interaction between the metal and its environment.TheseEnergetics and kinetics of hydrogen at the grain boundary The embrittlement degree of 2.25Cr-1Mo steel which is induced by hydrogen and temper embrittlement is Cp = log[4.9351×(Cp )1.31687 ]+Cp .Read more Article

Temper Embrittlement Susceptibility of Heavy Forgings
as temper embrittlementis mainly caused by changes in the microchemistry of grain boundaries,which becomes the preferred path for fracture .Temper embrittlement is a not-hardening embrittlement and stems from grain boundary segregation of impurity elements as a result of prolonged exposure in the temperature range of 350600 C.Temper Embrittlement Metallurgical ChangesMartensiticFatigueBrittle Fracture Thermal Fatigue imagesThe Embrittlement and Fracture of Steels Part Two The optimum temperature range for temper embrittlement is between 500 and 575°C.However,in some steels embrittlement occurs in the range 250-400°C.This phenomenon is called 350° embrittlement,and occurs at too low a temperature to attribute it to the diffusion of metalloids such as Sb to the austenite grain boundaries.
Temper embrittlement is inherent in many steels and can be characterized by reduced impact toughness.The state of temper embrittlement has practically no effect on other mechanical properties at room temperature.Many alloy steels have two temperature intervals of temper embrittlement.For instance,irreversible temper brittleness may appear within the interval of 250-400°C and reversible temper brittleness,within 450-650°C.Temper embrittlement of HTLA Cr-Mo SteelsJan 08,2011·Temper Embrittlement of Heat treatable Low alloy Mn-Cr-Mo Steel depends upon presence of certain elemnts like P,Sn,Mn,Si,Sb,As and this embrittlement happens during PWHT,or SR,or in-service exposure within temperature zone of 450 - 550C preferably due to preferntial segregation of tramph impurities at the prior austenite grain boundary which reduces the impact
What is temper embrittlement, and how can it be controlled 410 stainless steel temper embrittlement
Temper embrittlement refers to the decrease in notch toughness of alloy steels when heated in, or cooled slowly through, a temperature range of 400°C to 600°C. Temper embrittlement can also occur as a result of isothermal exposure to this temperature range. The occurrence of temper embrittlement can be determined by measurement of the change in the ductile to brittle transition temperature with a What is temper embrittlement,and how can it be controlled In order to assess susceptibility to temper embrittlement in Cr-Mo steels,two compositional parameters are commonly employed,the Watanabe J factor (1) and the Bruscato X factor (2).J=(Mn + Si)(P + Sn) x10 4 (in wt %),has been applied to parent steels and weld metals.

For example the temper embrittlement resistance had to be proven via Step  Cooling Test; toughness values at -30 °C in mid-thickness and near surface where specified as 48/54 J (mindimum value/average value)and the hardness was limited to a maximum of 190 HB.
