Fracture Toughness of CIP-HIP Beryllium at Elevated Temperatures.

Abstract

The fracture toughness of CIP-HIP (Cold Isostatic Pressed-Hot Isostatic Pressed) Beryllium was determined using the short bar fracture toughness (K sub IcSB) method. The K sub IcSB value measured was 10.96 MPa x the square root of m at room temperature. This falls well within the expected range of 9 to 12 MPa x the square root of m as observed from previous fracture toughness measurements of beryllium. Toughness increased rapidly between 400 F and 500 F reaching a value of 16.7 MPa x the square root of m at 500 F.
