Further, both CSRO and CMRO of the same structure motif are different from the chemical order of the known second phase (here, B2). From a general perspective, it is anticipated that mechanically stable CMRO, along with CSRO, will enhance the mechanical property. CMRO of large sizes will...

The shape recovery property of SMSs after deformation of alloy in the martensite phase is dependent on the chemical composition (alloying elements) and grain size in the austenite phase [97]. 4.3.1. Fe–Mn system These alloy systems are considered a new area of interest in the subject of ...
Thermal barrier coating (TBC) spallation life during service in a gas turbine engine is largely determined by the chemical composition of the substrate and the interaction of the substrate with the coating system. Substrates are typically made of a high temperature metal alloy such as a gamma prim...
A strength-ductility balance at a high temperature above 1000° C., particularly a high temperature above 1050° C. is improved by rendering a chemical composition of Cr-based alloy into Cr: more than 60 mass % but less than 65 mass %, C+N: not more than 20 mass ppm, S: not more...
(after ODP) at very high stresses by lamination, without altering the global chemical composition of Ti alloys (the detailed processing procedure can be found in the Methods, Supplementary Fig.4and Supplementary Table1). On the one hand, these α nanoprecipitates serve as strong pinning particles...
The structure, the phase composition, the pattern of distribution of alloying elements in the structure, and the long-term strength of refractory alloy 45Kh26N33S2B2 in cast condition are studied. The degree of segregation of chemical elements in the 纬-solid solution and in the carbide ...
