Book excerpt: A study was made to evaluate the kinematics of grain boundary shear and to compare the results pertaining to crystallographic deformation with those reported in the literature. Melt-grown single crystals and bicrystals of high purityAl were tested in tension at extension rates of 8.20 x 10 to the -6th power to 10 to the -4th power cm/sec (strain rates of approximately 2.3 to 230%/hr) and at temperatures of 538 to 650 C. The bicrystal samples contained pure, symmetrical tilt or twist boundaries of 10, 32, 40, 88, and 90 degrees. Continuous stress and total extension and intermittent shear displacement data were obtained as a function of time. A yield point phenomenon which is caused by a small amount of pre-test deformation was observed for single crystals and to a reduced extent for bicrystals. Its presence is explained by a model based upon dislocation multiplication and the stress dependent velocity of dislocations. A yield stress for grain boundary shear which is associated with a thermally activated process was also observed.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a comprehensive study of plastic deformation of aluminum single crystals over a wide range of temperatures. The results of constant-stress creep tests have been reported for the temperature range from 400 to 900 degrees F. For these tests, a new capacitance-type extensometer was designed. This unit has a range of 0.30 inch over which the sensitivity is very nearly linear and can be varied from as low a sensitivity as is desired to a maxtium of 10 microinches per millivolt with good stability.

Available in PDF, EPUB and Kindle. Book excerpt: Written by the leading experts in computational materials science, this handy reference concisely reviews the most important aspects of plasticity modeling: constitutive laws, phase transformations, texture methods, continuum approaches and damage mechanisms. As a result, it provides the knowledge needed to avoid failures in critical systems udner mechanical load. With its various application examples to micro- and macrostructure mechanics, this is an invaluable resource for mechanical engineers as well as for researchers wanting to improve on this method and extend its outreach.
