Numerical Research of Fracture Toughness of Aged Ferritic-Martensitic Steel

Metals, 2020
Generally, material properties such as the modulus of elasticity, yield strength or fracture toughness are determined by conducting an experiment. Sometimes experimental determination cannot be done due to specific experimental conditions, lack of ...

Expanding the Genetic and Phenotypic Spectrum of POLRMT‐Related Mitochondrial Disease

Clinical Genetics, Volume 109, Issue 1, Page 167-175, January 2026.
We identified potentially damaging monoallelic and biallelic POLRMT variants in affected individuals from six unrelated families, thus extending both the clinical and genetic phenotypes of POLRMT‐related mitochondrial disease. ABSTRACT Mitochondrial diseases are a complex group of conditions exhibiting significant phenotypic and genetic heterogeneity ...

Influence of axial load on internal pressure creep of Mod.9Cr-1Mo circumferential welded pipe

Nihon Kikai Gakkai ronbunshu, 2015
Mod.9Cr-1Mo steel(P91) is widely used for high temperature pipes in ultra-super-critical thermal power plants. However it was recently reported that the creep damage was detected at heat affected zone(HAZ) in welded joints of the pipes so-called the ...

With or without you: Family and Career‐Work in a Demanding and Precarious Profession

Journal of Management Studies, Volume 62, Issue 8, Page 3386-3424, December 2025.
Abstract Family arrangements are crucial to people’s abilities to meet the high demands of professional careers; but most scholarship has examined stable, highly remunerated professions. To understand the relationship between career and family within the increasing number of precarious professions, we analyse interviews with 102 journalists.

Enhancing Welding Productivity and Mitigation of Distortion in Dissimilar Welding of Ferritic-Martensitic Steel and Austenitic Stainless Steel Using Robotic A-TIG Welding Process

Journal of Manufacturing and Materials Processing
The P91 martensitic steel and 304L austenitic stainless steels are two mainly used structural steels in power plants. The major problem in conventional multipass tungsten inert gas (TIG) welding of P91/304L steel is high heat input and joint distortion ...
