Temperature-dependent thermal expansivities of silicate melts: The system anorthite-diopside [PDF]

open access: yes, 1992
The temperature-dependent thermal expansivities of melts along the join anorthite-diopside have been determined on glassy and liquid samples using a combination of calorimetry, dilatometry, and Pt double bob Archimedean densitometry.

Development Of High-Resolution Mechanical Spectroscopy, HRMS: Status And Perspectives. HRMS Coupled With A Laser Dilatometer

open access: yesArchives of Metallurgy and Materials, 2015
Recent achievements in the development of low-frequency high-resolution mechanical spectroscopy (HRMS) are briefly reported. It is demonstrated that extremely low values of the loss angle, ϕ, (tanϕb = 1×10−5) can be measured as a function of frequency ...

Dilatometry of ball milled nickel nano powder during non-isothermal sintering [PDF]

open access: yesScience of Sintering, 2007
This work attempts to evaluate the sintering mechanisms of ball milled nanocrystalline nickel during nonisothermal heating. Samples showed a sintered density of 91.2% (theoretical) and grain growth up to 414 nm at 1273K.

The Influence of Silica Sand Granulometry and Sorting Level on Thermal Expansion [PDF]

open access: yesArchives of Foundry Engineering, 2023
The quality of the castings depends, among other influences, on the quality of the moulding mixture used. The silica sands used are characterized by high thermal expansion compared to other sands. The tendency to dilatation of the moulding mixture can be

Unit cell dilation technique for analyzing dilatometry data [PDF]

open access: yes, 2017
Dilatometry is the most accurate and common method for measuring the kinetics of phase transformations in solid specimens. Despite the development of a more accurate technique, an inferior method, i.e., the lever rule, is widely used in the scientific ...

Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment [PDF]

open access: yesScience of Sintering, 2017
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes that will happen during ...

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.
