MEMORANDUM on EFFECTS OF HIGH STRAIN RATES AND RAPID HEATING ON THE TENSILE PROPERTIES OF TITANIUM ALLOYS

摘要

Some structural members of supersonic aircraft and missiles may be subjected to both rapid heating and high rates of loading under certain service conditions. It has been shown by numerous investigators that strength properties tend to increase with increasing strain rate. Most researchers have ignored the effects of rapid heating, however. In order to properly assess the usefulness of materials under these conditions special testing techniques must be used.
