On the sensitivity of dimensional stability of high density polyethylene on heating rate

open access: yeseXPRESS Polymer Letters, 2007
Although high density polyethylene (HDPE) is one of the most widely used industrial polymers, its application compared to its potential has been limited because of its low dimensional stability particularly at high temperature.

Influence of Austenitisation Temperature and Time on Martensitic and Isothermal Bainite Phase Transformation of Spring Steel

open access: yesMetals, 2022
The influence of austenitisation temperature and time on the martensitic and isothermal bainite transformation of 51CrV4 spring steel was analysed. Based on the analysis of dilatometric curves, the martensite start temperatures (MS) were determined at ...

Optical Dilatometry and Push-Rod Dilatometry—A Case Study for Sintering Steel and Zirconia Tapes

open access: yesJournal of Experimental and Theoretical Analyses
In this work, the sintering behavior of tapes prepared via tape casting from stainless-steel and zirconia powders is investigated by optical—as well as push-rod—dilatometry. Both methods are compared in terms of sample preparation, measurement conditions,

Effect of two-step ausforming on bainite transformation and retained austenite in a medium-carbon bainitic steel

open access: yesMaterials Research Express, 2020
It is commonly accepted that single ausforming with small strain at low temperature promotes isothermal bainite transformation and leads to more retained austenite.

Analyzing the Sintering Kinetics of Ti12.5Ta12.5Nb Alloy Produced by Powder Metallurgy

open access: yesMetals, 2023
The focus of this work is to analyze the sintering kinetics of Ti12.5Ta12.5Nb alloy by dilatometry. The mixture of powders was achieved by mixing individual powders of Ti, Ta and Nb, which were then axially pressed.

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Impact of Electrolyte Formulation on the Phase Behavior and Interphase Formation of Sb/Graphite Electrodes for K‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Electrolyte formulation is shown to govern both interphase chemistry and bulk phase evolution in Sb/graphite anodes for potassium‐ion batteries. A diglyme‐based localized high‐concentration electrolyte promotes a thin inorganic‐rich interphase, suppresses deep graphite potassiation, limits electrode swelling, and stabilizes amorphous KxSb formation ...
