The effect of grain size on workhardening and superplasticity in Zn/0.4% Al Alloy [PDF]
, 1969 Superplasticity*requires, amongst other things, a metal with a grain-size in the range 0.5-5μ. Theories of SP invoking dynamic recovery require that the cell-Size of the substructure for the alloy in question is larger than the SP grain-size, so that ...

Arthritis Care &Research, EarlyView.Objective Patients with knee osteoarthritis rely on symptomatic treatments, in which up to 75% of the pain reduction can be attributed to the placebo effect. This effect may vary based on treatment type (eg, biologics vs nonbiologic injection) and route of administration (eg, intra‐articular vs topical vs oral).

Novel sputtering-technology for grain-size control [PDF]
, 2004 In this paper, we present a description of a novel high-rate plasma sputtering system that allows the control of grain size in sputtered films. Additionally, the system has the advantage of a better utilization of the target material (around 80% to 90 ...

Effect of Grain Size on Mechanical and Creep Rupture Properties of 253 MA Austenitic Stainless Steel
Metals, 2022 The effect of grain size on the mechanical properties and creep rupture of 253 microalloyed (MA) austenitic stainless steel (ASS) was investigated. The cold rolling process with a 53% reduction in thickness was applied to the steel followed by annealing ...

Ageism in Rheumatology: the Healthcare Professional's Perspective
Arthritis Care &Research, Accepted Article.Objective Ageism (age‐based stereotypes, prejudice, or discrimination) is prevalent and linked to prolonged disability and reduced lifespan in older adults. Little is known about ageism within rheumatology. This study explores the healthcare professional's (HCP) perception of the care of older adults and how ageist attitudes or perspectives may impact ...

Advanced Engineering Materials, EarlyView.AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by
