The ZrO2 Formation in ZrB2/SiC Composite Irradiated by Laser
In order to clearly understand the details of ZrO₂ formation during ablation, high intensity continuous laser was chosen to irradiate ZrB₂/SiC. The results reveal that there are two different modes of ZrO₂ formation depending on whether liquid SiO₂ is present. When liquid SiO₂ is present, ZrO₂ generated by the oxidation of ZrB₂ is firstly dissolved into SiO₂. Then, ZrO₂ will precipitate again, ...
متن کاملThermal Shock Properties of ZrB2-SiCp-Graphite and ZrB2-SiCp-AlN Ceramic Matrix Composite Material
Thermal shock property of the material can be improved by improving fracture property of the material. In this paper, factors affecting fracture property have been studied and the effect of residual stress, microstructure, strain rate and stress concentration on fracture property of material has been analyzed, which may provide help for improving thermal shock property of material. Thermal shoc...
متن کاملFabrication and inspection of C/Cf-ZrB2-ZrC-SiC and C/Cf-ZrB2-SiC composite parts resistant to ablation by pressureless sintering method
In this research, the aim is to achieve strong and ablation-resistant composite parts C / Cf-ZrB2-ZrC-SiC and C / Cf-ZrB2-SiC by non-pressure sintering method. C / Cf-ZrB2-SiC samples were prepared using synthesized ZrB2 and SiC powders between layers of resin-impregnated carbon fabric. After pressing with pressure 5 times at 1600 وC and heat treatment for 2 hours in a controlled atmosphere fur...
متن کاملInvestigation of Effective Parameters on Densification of ZrB2-SiC Based Composites Using Taguchi Method
Abstract The main goal of this study is optimization of densification of ZrB2-SiC composites reinforced with chopped Cf prepared by SPS. Taguchi method is employed as statistical design of experiment (DOE) to optimize densification parameters including SiC, Cf, MoSi2, HfB2 and ZrC content, milling time of Cf and SPS parameters such as temperature, time and pressure. Each of these factors ...
متن کاملEffect of Milling on the Mechanical Properties of Chopped SiC Fiber-Reinforced ZrB2
This work aims at studying the effect of the milling conditions on the microstructure and mechanical properties of a ZrB₂-5 vol% Si₃N₄ matrix reinforced with chopped Hi-Nicalon SiC fibers. Several composites were obtained using different milling conditions in terms of time, speed and type of milling media. The composites were prepared from commercial powders, ball milled, dried and shaped, and ...
