Carbon-Nanotube-Reinforced Polymer-Derived Ceramic Composites
Linan An,Weixing Xu,Sudhir Rajagopalan,Chongmin Wang,Hsin Wang,Yi Fan,Ligong Zhang,Dapeng Jiang,Jay Kapat,Louis C. Chow,Baohua Guo,Ji Liang,Raj Vaidyanathan +12 more
TL;DR: In this paper, carbon nanotube reinforced ceramic composites were synthesized by using recently developed polymer-derived ceramics as matrices, and significant increases in mechanical and thermal properties were observed by adding only 6vol% nanotubes.
Journal ArticleDOI
Elastic modulus of shape-memory NiTi from in situ neutron diffraction during macroscopic loading, instrumented indentation, and extensometry
TL;DR: The elastic modulus of B19' shape-memory NiTi was determined using three techniques; from the response of lattice planes measured using in situ neutron diffraction during loading, instrumented indentation using a spherical indenter and macroscopic extensometry.
Journal ArticleDOI
Application of Gaussian Process regression models for capturing the evolution of microstructure statistics in aging of Nickel-based superalloys
TL;DR: In this article, the principal component (PC) representation of rotationally invariant 2-point spatial correlations can adequately capture the salient features of the microstructure evolution in the thermal aging of the superalloys.
Journal ArticleDOI
Application of spherical indentation and the materials knowledge system framework to establishing microstructure-yield strength linkages from carbon steel scoops excised from high-temperature exposed components
TL;DR: In this paper, a novel spherical microindentation technique is applied to evaluate a library of scoop samples ranging between 0 and 99,000h of service, and microstructure and yield strength data for the different exposure periods are used to construct a structure-property (S-P) linkage using the MKS homogenization approach that employs spatial correlations, principal component analysis, and regression techniques.
Journal ArticleDOI
Structure and property evaluation of a vacuum plasma sprayed nanostructured tungsten-hafnium carbide bulk composite
Keith E. Rea,Venkatachalapathy Viswanathan,A. Kruize,J.Th.M. De Hosson,S. O'Dell,T. McKechnie,Sudhir Rajagopalan,Raj Vaidyanathan,Sudipta Seal +8 more
TL;DR: In this paper, high resolution transmission electron microscopy (HRTEM) revealed the retention of nanostructures at the select process conditions and correlated with the enhanced mechanical properties of the nanocomposite.
