Book Description
The effects of temperature, strain rate, and strain on densification and hardness of direct powder forged metal matrix composites was analyzed. Manufactured by Materion Brush, the MMCs were premixed, mechanically-alloyed, agglomerate powders of Al6061/20%/SiCp/0.7μm and Al6061/40%/SiCp/3.0μm. Open-die direct powder forging was conducted on 80% relative density, green powder compacts under temperatures ranging from 475 to 550 oC, with strain rates from 0.001/s to 0.1/s, and strain levels from -0.16 to -1.51 true strain. Flow stress increased with a decrease in temperature or increase in reinforcement volume fraction and exhibits little softening under the conditions tested in this study. Relative density values up to 97% were achieved in the center region of the ~38 mm diameter DPF billet, requiring forging loads of less than 50 kN, ~15 times lower than unreinforced aluminum in a closed die. Within the chosen range of temperatures and strain rates, strain was determined to have the largest effect on densification. Vickers microhardness show the strongest correlation with density and increases with true strain.

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.

Book Description
The effects of strain rate and temperature on the mechanical behavior of a magnesium alloy (ZC71) and its corresponding composite reinforced with SiC particles are investigated. The experimental procedures of testing at high strain rate and different temperatures are described. The tensile stress-strain responses of both the base and the reinforced materials were found to depend on the applied strain rate (0.003

Book Description
Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.
