Materials and design interface

A study on martensitic phase transformation in 9Cr–1W–0.23V–0.063Ta–0.56Mn–0.09C–0.02N (wt.%) reduced activation steel using differential scanning calorimetry

“…It is needless to stress the fact that a fundamental study on thermodynamics and kinetic considerations of phase stability is indeed germane to evolving a strategically transparent approach to alloy design [85]. It is amidst this background that we have undertaken in our recent study on the indigenously developed reduced activation ferritic-martensitic (RAFM) steel, a comprehensive calorimetry characterisation of various onheating diffusional phase transformations up to melting [86].…”

A calorimetric study of high temperature phase stability in Fe–U alloys

“…In the domain of materials design for advanced nuclear power generating systems, the availability of critically assessed high temperature phase stability and thermal property data is indeed vital from the point of view of facilitating the knowledge driven approach to materials selection, component design and subsequent fabrication [1]. It is generally well-appreciated that in so far as emerging new reactor concepts are concerned, the candidate materials are expected to perform under more stringent operating conditions with tighter safety margins as compared to older designs [2].…”

Drop Calorimetry Studies on 9Cr–1W–0.23V–0.06Ta–0.09C Reduced Activation Steel

“…It is well known that the availability of reliable and critically assessed thermodynamic data is essential for facilitating the knowledge-driven approach to alloy design [1]. At present, there is an urgent need for generating accurate high-temperature thermochemical and thermophysical property information on many advanced engineering alloys that are slated for applications in conventional and emerging power generation options [2].…”

“…At present, there is an urgent need for generating accurate high-temperature thermochemical and thermophysical property information on many advanced engineering alloys that are slated for applications in conventional and emerging power generation options [2]. The profitable understanding of factors that govern ultimately the materials selection and component design depends to a large extent on our ability to successfully model and simulate the degradation mechanisms that the chosen candidate material is expected to experience during its normal service or under hypothetical accident conditions [1]. While the modelling of materials performance during service is veritably a daunting task when viewed in its entirety of scope and perspective, it is nevertheless useful to address this issue in a compartmentalized manner.…”

“…In the area of such hierarchical, multi-tiered approach to materials modelling, there has been a sustained effort over the last decade towards developing successful thermodynamic and kinetics protocols that aim at rationalizing or predicting the phase and microstructural stability of advanced engineering materials at the level of classical thermodynamics and continuum mechanics. In such an approach it is difficult to overemphasize the pivotal role played by reliable material property data [1,2].…”
