The influence of various gaseous environments on the rate of fatigue crack growth at room temperature in an 0.45 percent carbon low-alloy ultra-high-strength steel tempered at 400ยฐF and at 800ยฐF has been investigated. The sensitivity of the rate of fatigue crack growth to moisture in this steel is f
The critical intensity factor K,, of a single crystal alumina (1100)-plane in air and in a simulated body environment was measured. Based on these measurements, the esti- mated durability of a single crystal alumina disk in a ceramic heart valve was determined. Standard single-edge notched beam spec
## Abstract Fracture toughness and modulus of rupture tests have been carried out on three aluminas, which differed in composition and microstructure, in a variety of environments (air, deionized water, albumen/salt solution, Ringer's solution, and fresh human plasma). Generally tests in liquid env
