A quantitative fractographic analysis was undertaken in order to relate important microstructural and fractographic features to fatigue fracture in a Ti-28V alloy. Special emphasis is placed on facet characteristics and subsurface cracking in the sin

As the result of years of work, a new, quantitative treatment of the geometrical attributes of metallic fracture surfaces has emerged. Modern advances utilize the powerful relationships of stereology to give quantitative descriptions of the fracture

The fractal characteristics of a series of fractured AISI 4340 steel specimens were studied experimentally by means of vertical sections through the fracture surface. Extensive fractal data have been generated for both the fracture surfaces and their

Stereology is the study of the three-dimensional structure of materials from two-dimensional sections or projections. By suitable statistical measurements on the test plane or projection plane, and by utilizing the basic equations of stereology, the

Defect structures in superplastic and nonsuperplastic Al-Zn eutectoid alloys were studied by transmission electron microscopy. Slowly cooled alloys develop a fine lamellar microstructure and are not superplastic. The equiaxed quenched and quench-aged

SUMMARY A generalized, geometrical approach is adopted in reviewing the basic relationships of projected structures. Projections of features from a plane to a projection line, and from a three-dimensional foil to a projection plane are considered bri

A new series of ductile Be-Al alloys are described which have the advantages of Be, viz., high modulus and low density, but without many of the disadvantages of unalloyed Be. Mechanical properties of the alloys can be varied considerably (tensile str
