Composite Strengthening of Nb-Ti Base Alloys

Authors: M. G. Benz; M. R. Jackson; J. R. Hughes; GENERAL ELECTRIC CO SYRACUSE NY RESEARCH AND DEVELOPMENT CENTER*

Although Nb-Ti-Cr-Al alloys have attractive oxidation and oxygen embrittlement resistence, they have relatively low strengths; the use of composite technology to strengthen these alloys is investigated.

Mechanical Properties of Diverse Binary High-Temperature Intermetallic Compounds

OCT 90

Authors: R. L. Fleischer; R. J. Zabala; GENERAL ELECTRIC CO SYRACUSE NY RESEARCH AND DEVELOPMENT CENTER*

A suite of 29 binary, single-phase alloys that includes 18 different ordered intermetallic crystal structures has been tested. Microhardness and tendency toward formation of cracks are reported as a function of temperature; room-temperature Young's moduli are quoted; and results of simple room- temperature toughness tests are given. Using toughness, low specific gravity, and hardness at 1000 deg C as figures of merit, several alloy systems are recognized as deserving of ...
