One of the most important technical issues for large-scale ceramic components is their quality stability (viz., differences in material properties depending on the part and the processing), which might influence the structural and/or thermal reliability through unforeseen deformation and breakage. In this study, the authors used a simple, low-cost method for evaluating the properties of SiC mirror materials. Using mechanical testing, thermodilatometry, and microstructural analysis on samples cut from the periphery of a prototype 800-mm-diameter mirror body, the overall quality of the mirror body material was determined., 資料番号: PA1420012000}, pages = {850--858}, title = {Evaluation of Spaceborne SiC Mirror Materials Using Samples Cut from the Periphery of a Mirror Body}, volume = {23}, year = {2014} }
