Investigation on Particulate/Matrix Interface Bonding in Al Matrix Composites. 1994
Authors:  Y. H. Teng; J. D. Boyd; RISOE NATIONAL LAB ROSKILDE (DENMARK)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Particulate/matrix interface strength is an important parameter in relation to the mechanical behaviour of particulate reinforced metal composites. the present work investigates the degree of interface bonding in commercial al6061-al2o3 particulate composites using a critical stress partition model. this model correlates the composite tensile properties with the strengths of particulate, matrix and interface, and also with some fracture parameters. based on the results on tensile testing, micro-indentation and quantitative fracture ...

Effects of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Ti-V-N Steel, MAY 1988
Authors:  B. Dogan; L. E. Collins; J. D. Boyd
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Based on studies of austenite deformation behavior and continuous-cooling-transformation behavior of a Ti-V microalloyed steel by cam plastometer and quench-deformation dilatometer, respectively, plate rolling schedules were designed to produce recrystallized austenite, unrecrystallized austenite, and deformed ferrite + unrecrystallized austenite. The effects of austenite condition and cooling rate on the final microstructure and mechanical properties were investigated. To rationalize the variation in final ferrite grain size with different thermomechanical processing schedules, ...
