Book Description
The composite material consists of 25 volume percent of silicon carbide whiskers in 2014-T4 aluminum matrix. Specimens were taken from hot-isostatically-pressed cylindrical billets and tested at various loading conditions and strain rates. Tension and compression tests were performed at strain rates of 10-4 and 5 S-1 to determine the effect of strain rate. Bauschinger effect was investigated by precompressing specimens to two strain levels followed by reversing load to tension until fracture occurred. Torsion tests were carried out to determine the relationship between torque and twist angle. The KIc-value was determined by testing short-rod specimens. The tensile properties and KIc were compared with those of 2014-T4 aluminum to demonstrate the effect of silicon carbide whisker reinforcement on the properties of matrix materials.
