Polymer Testing | Year: 2010

Measurements of the glass transition temperature obtained by dynamic mechanical analysis (DMA) and temperature modulated differential scanning calorimetry (TMDSC) are reported to be different. This was mainly attributed to the frequency effect. To obtain comparable measurements, experimental conditions were studied. Although some experimental issues had to be fixed, it was possible to apply the same frequency and temperature using quasi-isothermal conditions in both instruments. The method was tested with three different polymer samples. It was then found that when choosing a suitable response parameter, i.e. the phase angle, the dynamic glass transition temperature values obtained by both methods are practically the same. © 2010 Elsevier Ltd.

CIRP Annals - Manufacturing Technology | Year: 2016

Directed energy deposition (DED) for producing a complex shaped metal part has attracted attention in the aerospace industry. However, DED easily causes structural defects such as voids and compositional changes, which results in the deterioration of the mechanical strength of the product. Hence, reducing such defects is essential. In this study, the influence of the powder characteristics of Inconel 625 was focused upon, and the void density and compositional change inside the deposited part were analyzed. The results indicated that a slight amount of carbon in the particle caused void generation and a carbon layer was formed at the surface. © 2016 CIRP.
