- Summary
-
Hot-pressed, hot-upset and hot cross-rolled Be sheets were examined to assess their differences and advantages from a structural design viewpoint. Tension, notch tension, compression, bend ductility and box-beam tests, with the main emphasis on factors which tend to embrittle Be, were conducted. The results showed that hot cross-rolled Be sheet exhibited both high strength and high elongation in tensile tests but was relatively brittle when, as in bending, the stress was complex. Hot-pressed Be sheet, which was low in tensile strength and elongation, demonstrated an excellent capacity for accommodating complex stresses in bending without fracture. The hot-upset Be sheet exhibited the best characteristics possessed by both hot-pressed and hot cross-rolled Be, though to a lesser degree than the optimum of each. The differences in mechanical behavior among the 3 groups were apparently a function of the degree of preferred orientation. However, the amounts of impurity elements which were reported could have contributed significantly to the embrittlement of the hot- pressed and hot cross-rolled Be sheet.
