Strength And Ductility

Since writing on this subject two years ago [1], a number of developments have occurred, particularly in relation to the mechanical properties of the L12 nickel aluminide Ni3Al. Some elucidate the nature of the yield strength and the extraordinarily beneficial effect of boron on low-temperature ductility. Some others expose, at least in part, the nature of the marked reduction in ductility at elevated temperatures. Another considers the mechanisms dominating creep deformation. Also during this period, contradictions have appeared: the relationship between the yield strength and the grain size, d, at room temperature has been contested, and opposing views of grain refinement on ductility have been reported.This paper reviews these developments. Although broadly directed at intermetallic compounds, the discussion is specific to Ni3Al. The hope is that the knowledge and understanding gained about this compound will benefit the class as a whole.

ABSTRACTCast, homogenized, and isothermally forged aluminum-rich L12 compounds Al87Ti25Cr8 and Al66Ti25Mn9 were tested in compression as a function of temperature and as a function of strain rate at elevated temperatures (1000K and 1100K). Three-point bend specimens were tested as a function of temperature in the range 300K to 873K. Strain gages glued on the tensile side of the ambient and 473K specimens enabled direct strain measurements. A number of “buttonhead” tensile specimens were electro-discharge machined, fine polished, and tested between ambient and 1073K for yield strength and ductility as a function of temperature. Scanning electron microscope (SEM) examination of fracture surfaces from both the bend and tensile specimens revealed a gradual transition from transgranular cleavage to intergranular failure with increasing temperature.

Strength And Ductility

Abstract One of the important problems in determining the usefulness of stainless steels as cladding materials in high-temperature gas-cooled reactors is the effect of chemical reactions between clad and coolant on the cladding strength and ductility. The mechanism by which the coolant (CO2 in this investigation) affects the strength properties of Type 304 stainless steel are being investigated in the range 1300 to 1700 F (704–927 C). Creep- and stress-rupture results obtained on sheet materials in wet and dry CO2 and argon are compared. The effect of annealing in CO2 on the tensile strength and ductility is also reported. The question of whether the strengthening observed in CO2 was due to oxidation or carburization was investigated. Experiments on the effect of various partial pressures of oxygen in argon showed that the creep rate was minimum at approximately 10 ppm. The creep rate in CO2 at equivalent stress and temperature was one-third the minimum rate observed in oxygen. Chemical analyses, metallography, and experiments with isotopic carbon showed that carburization occurred in pure flowing CO2 in the temperature range studied. From this evidence it was concluded that the strengthening observed in CO2 was primarily due to carburization. The creep- and tensile-fracture strains were adversely affected by exposure to CO2 with the magnitude of the effect dependent on the time and temperature of exposure.
