Characterization of precipitates in strip-cast 2.7%Si steel under different heat treatment conditions

open access: yesMATEC Web of Conferences, 2015
A 1.5mm thickness as-cast Fe-2.7%Si strip was produced by twin-roll strip casting and the precipitates under different isothermal holding time (0.5 min–30 min) and cooling rates (1∘/s–20 ∘C/s) were investigated by thermal simulation experiment technology

Management of Auricular Hematoma With Bolster Versus Quilting: A Retrospective Cohort Study

open access: yesThe Laryngoscope, EarlyView.
This retrospective cohort study compared outcomes between bolster dressings and through‐and‐through mattress quilting sutures in the management of auricular hematoma in 43 patients. Recurrent hematoma occurred in 30% of the bolster group and 0% of the quilting group, with no significant differences in complications observed between the two groups ...

Analysis of Gap Formation in the Casting of Energetic Materials

open access: yes, 2007
The problem of undesirable separation of the cast material from the mold in the casting of energetic materials is investigated. Comprehensive models are developed to simulate the heat and mass transfer processes during melt casting of energetic materials,

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

open access: yesPolymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.
