Hiroshi Harada focuses on Metallurgy, Superalloy, Alloy, Microstructure and Ultimate tensile strength. As a part of the same scientific study, he usually deals with the Metallurgy, concentrating on Single crystal and frequently concerns with Composite material. Hiroshi Harada integrates several fields in his works, including Superalloy and Ruthenium.
Hiroshi Harada has included themes like Creep, Turbine, Base and Volume fraction in his Alloy study. He has researched Microstructure in several fields, including Titanium alloy, Condensed matter physics and Phase diagram. In his study, Grain size, Grain boundary strengthening, Vickers hardness test and Crystal twinning is strongly linked to Annealing, which falls under the umbrella field of Ultimate tensile strength.
The scientist’s investigation covers issues in Superalloy, Metallurgy, Alloy, Creep and Single crystal. When carried out as part of a general Superalloy research project, his work on Nickel base is frequently linked to work in Base, therefore connecting diverse disciplines of study. In his research on the topic of Metallurgy, Diffusion is strongly related with Coating.
His Alloy course of study focuses on Chromium and Titanium. His studies examine the connections between Creep and genetics, as well as such issues in Turbine, with regards to Gas turbines. His Single crystal research integrates issues from Dislocation and Chemical composition.
His scientific interests lie mostly in Superalloy, Metallurgy, Single crystal, Creep and Alloy. His Superalloy study combines topics from a wide range of disciplines, such as Ultimate tensile strength, Stress and Base. His Metallurgy research includes elements of Fracture mechanics and Dislocation.
Hiroshi Harada combines subjects such as Dendrite, Nickel base and Phase stability with his study of Single crystal. His research in Creep intersects with topics in Paris' law, Yield, Ingot and Single crystal superalloy. The Alloy study combines topics in areas such as Condensed matter physics, Diffraction, Ceramic and Anisotropy.
Hiroshi Harada mainly focuses on Metallurgy, Superalloy, Alloy, Fracture mechanics and Single crystal. His research is interdisciplinary, bridging the disciplines of Nuclear chemistry and Metallurgy. In his articles, he combines various disciplines, including Superalloy and Science, technology and society.
His studies deal with areas such as Crystal twinning and Fracture as well as Fracture mechanics. Hiroshi Harada works mostly in the field of Oxide, limiting it down to concerns involving Toughness and, occasionally, Turbine. His biological study spans a wide range of topics, including Annealing, Precipitation hardening, Microstructure, Grain boundary strengthening and Grain size.
