The Impact of Weld Metal Creep Strength on the Overall Creep Strength of 9% Cr Steel Weldments [PDF]
Journal of Engineering Materials and Technology, 2011 In this work, three joints of a X11CrMoWVNb9-1-1 (P911) pipe were welded with three filler metals by conventional arc welding. The filler metals varied in creep strength level, so that one overmatched, one undermatched, and one matched the creep strength of the P911 grade pipe base material.

Creep Strength of Turbine Discs
Transactions of the Japan Society of Mechanical Engineers, 1948 高壓高温のタービン圓板では匍匐のため,その外周が膨脹して翼先端とケーシング内壁とが接觸するに到る恐があるゆえ,匍匐變形を考慮した設計が必要である.本報告はその近似計算法を述べようとするもので,匍匐状態を初期匍匐状態と整定匍匐状態とに分ち,まず整定匍匐状態における應力分布をC. R. Soderbergの基礎式より出發して階差法によりて求め,かゝる應力状態が初期匍匐状態においても成立しているものと假定することにより匍匐量が實際よりかなり大き目に求まる方法を提唱し,最後に一計算實例を示した.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
