Summary: Silicon carbide fiber-reinforced silicon carbide ceramic matrix composite (SiCf/SiC) shows great potential for manufacturing aero-engines due to its high-temperature resistance and lightweight properties. However, the machining process of SiCf/SiC is challenging due to the material's hardness and brittleness, which often results in uncontrolled damages such as edge chipping, cracks, and fiber breakage. This research focuses on studying the edge chipping characteristics of SiCf/SiC during single grain grinding. The study finds that the edge chipping in SiC matrix grinding is influenced by pre-existing defects, while the edge chipping in SiC fiber grinding is dependent on both fiber orientation and grinding speed. Grinding perpendicular to the fiber orientation results in larger edge chipping compared to grinding along with the fiber orientation, and higher grinding speeds also decrease the width of the edge chipping area. Therefore, increasing grinding speed can enhance material removal rate without enlarging edge chipping, which is crucial for achieving desired surface finish and damage control in the machining of SiCf/SiC.

Summary: This study introduced the laser-ablating assisted grinding (LAAG) method to investigate the surface/subsurface damage behavior of C-f/SiC composite. It was found that SiO2 ablation products with a loose structure were formed during picosecond-laser ablating, and the ablated layers showed excellent machinability during grinding. LAAG resulted in significant ductile fracture and smeared removal appearance on the ground surfaces, while conventional grinding (CG) led to brittle removal of the composite. The grinding forces during LAAG decreased with increasing grinding speed, and the brittle-ductile transformation of the normal fiber became more significant. The increase of feed speed increased the grinding forces and enhanced the brittle removal behavior. The laser power affected the machined quality through the ablation depth and the ablative transformation.

Summary: Quasi-isotropic carbon fiber-reinforced pyrolytic carbon and silicon carbide matrix (C-f/C-SiC) composites and chopped silicon carbide fiber-reinforced silicon carbide matrix (SiCf/SiC) composites were prepared using an airlaid process combined with chemical vapor infiltration. The composites showed random fiber distribution and homogeneous pore size. The C-f/C-SiC composites exhibited higher tensile strength and interlaminar shear strength compared to the SiCf/SiC composites due to the appropriate interfacial shear strength and introduction of low-modulus and highly textured PyC matrix.

Summary: This study investigates the effect of grinding steps on the mechanical behavior of SiC/SiC composite fuel cladding tubes. Different depths of inner and outer surface grinding were carried out, followed by cyclic tensile tests and elastic behavior analysis. The results show that machining of the tubes does not cause pre-damage, internal slippage is not dependent on seal coat thickness, and surface quality has a weak influence on damage in the loading direction, while damage in the shear plane and ultimate failure strength strongly depend on the inner seal coat thickness.

Summary: The study found that the FMA at the CFRP stage has a significant impact on the microstructure and mechanical properties of C/C-SiC composite fabricated via LSI. A higher FMA led to nonhomogeneous distribution of SiC matrix, while a lower FMA resulted in uniform distribution and a strong bonded C-SiC interface. Control of interface bonding by modifying FMA at the CFRP stage is crucial for achieving desired mechanical properties of C/C-SiC composite.

Summary: The modified precursor infiltration pyrolysis (PIP) method was used to prepare an integrated doped ceramic matrix and coating with SiC nanowires, resulting in a composite with improved bonding strength and ablation resistance. The integration of the coating and matrix enabled the formation of a continuous oxide layer in the ablation process, effectively blocking oxygen and heat. This systematic improvement led to significantly lower mass and linear ablation rates compared to traditional composites.

Summary: Fiber bending by the cutting tool is a major cause of fiber pull-out during CFRP milling. The shear stress on the polymer matrix between fibers leads to debonding, and the strain energy absorbed by the deformed matrix is released into fiber-matrix debonding, causing fiber pull-out on the machined surface.

Summary: Different heat treatment methods were used to investigate the impact on the strength and toughness of TA15 aviation titanium alloys. Increasing the annealing temperature led to an increase in phase boundary and secondary a phase, while the volume fraction of primary a phase decreased, resulting in an increase in hardness and a decrease in elongation. Heat treatment at 810 degrees C/2 h/WQ produced the highest tensile properties, and higher temperatures enhanced hardness but decreased tensile properties, bending strength, and impact toughness. Triple heat treatment (810 degrees C/1 h/AC + 810 degrees C/1 h/AC + 810 degrees C/1 h/AC) resulted in the highest hardness.

Summary: Micro-grinding is an important step in most surgical operations, but technical challenges such as insufficient cooling capacity, poor visibility, and high grinding temperature have hindered its progress. To address these issues, a new micro-grinding process called ultrasonic vibration-assisted nanoparticle jet mist cooling (U-NJMC) is proposed, combining the advantages of ultrasonic vibration and nanoparticle jet mist cooling. The combined effect of U-NJMC on cooling has been investigated and compared to other grinding methods. Results show that U-NJMC significantly reduces grinding force, friction coefficient, specific grinding energy, and grinding temperature, making it a promising approach for clinical surgical micro-grinding of biological bone.
