TL;DR: There is a possibility to develop bone substitutes that can repair bone defects and promote new bone formation for orthopedic applications, and some effective strategies to enhance cell ingrowth in bone engineered tissues are discussed.

TL;DR: In this article, a design of experiments approach (Taguchi L25 orthogonal array) was adopted to statistically determine the influences of individual process parameters, including oscillation amplitude, welding speed, normal force, operating temperature, and fiber orientation, on bond formation and fiber/matrix bond strength.

TL;DR: In this article, the authors examined the effects of various process parameters on linear weld density (LWD) in ultrasonically consolidated aluminum alloy 3003 parts and proposed strategies to ensure near 100% LWD.

TL;DR: In this article, an analytical energy model aimed at investigating the effects of process parameters on bond formation in ultrasonic consolidation was presented, where two factors were defined, energy input to the workpiece within a single cycle of ultrasonic vibration (E0) and total energy input (Et), to evaluate to the magnitude of transmitted energy into the work piece during UC and it was found that linear weld density, E0 and Et are affected by process parameters in similar manners.

TL;DR: In this article, the results of mechanical testing were discussed based on microstructural and fractographic studies, and they showed that incorporation of SiC fibers resulted in a considerable improvement in peel strength and tensile strength of ultrasonically consolidated parts.
