The paper contains the results of experimental work on caustic embrittlement. The type of apparatus chosen was based on one used in recent American work carried out by Straub and Bradbury (1938). In this, the solution to be tested is contained in a hollow sealed tubular specimen, heated to any desired temperature in the steam boiler range, and ...

The effects of hydrogen on the fracture of metals will be reviewed using a selection of observations based on the use of in situ environmental cell experiments. These were developed to allow understanding of the mechanisms of the failure process. The in situ technique, combined with use of the environmental cell, is well suited to mechanistic studies ...

In general, materials tend to increase in strength as their temperature is lowered. The deformation of metals occurs with the movement of crystal-lattice dislocations. As the temperature is raised, the thermal energy of the vibrating atoms assists this movement.

Embrittlement of a metal is measured by the amount of plastic or creep deformation that occurs before fracture. Irradiation invariably renders a metal less ductile than the unirradiated condition. Fracture can be of the brittle type in which a small crack rapidly propagates across an entire component, or it can occur after long times at stress and ...

Mechanism of Embrittlement and De-Embrittlement for 2. 25Cr-1Mo Steel
Journal of Iron and Steel Research International, 2011The constant embrittlement curve for constant segregation concentration on grain boundary of impurity element P and relationship between equilibrium grain boundary segregation concentration and operation time for 2. 25Cr-1Mo steel were derived based on the theory of equilibrium grain boundary segregation.

Abstract In the introductory section of this paper, boiler embrittlement as a field of study is traced back toward the very invention and genesis of steam boilers. The study is traced through the miscellaneous researches of several countries up to the establishment of unified research in three institutions: Britain’s National Physical ...

The Age- Embrittlement of Silver Coins
Studies in Conservation, 1954THAT certain ancient silver articles, including coins, have in the course of time become exceedingly brittle is fairly well known. Silver coins which have been struck must have been ductile at the time of manufacture and hence have become brittle as a result of some sort of ageing process. This form of embrittlement has been observed in silver coins of

Abstract This article examines the embrittlement of iron and carbon steels. It describes compositional, processing, and service conditions that contribute to the problem and presents examples of how embrittlement influences mechanical properties. Embrittlement due to hydrogen is the most common form of embrittlement and influences the
