Processing and Thermomechanical Properties of PHA

2020
The biodegradability and biocompatibility of PHAs make them a class of materials with wide range of applications, raising interest of scientist and industries. PHAs applications are limited by a narrow processing window, easy degradation during melt processing, variable crystallization rate and high crystallinity of commercial PHA grades.

Thermomechanics of Biomaterials Freezing Process

Advances in Heat and Mass Transfer in Biological Systems, 1994
Abstract Large volumetric expansion during freezing of biomaterial, combined with phase change over a temperature range leads to thermal stresses and fractures. A viscoelastic model was used to analyze the transient symmetric freezing of a long cylinder (plain strain problem).

Thermomechanical processing of 42CrMoS4 steel

International Heat Treatment and Surface Engineering, 2010
AbstractBillets of 42CrMoS4 steel were subjected to a programme including forging and rolling to different reduction ratios, followed by quenching and tempering to simulate online thermomechanical treatment (TMT) during rolling. The mechanical properties obtained were compared with those obtained by conventional heat treatment (CHT) (quenching from 860°

Thermomechanical Processing of Ferrous Alloys

2005
Abstract Thermomechanical processing (TMP) refers to various metal forming processes that involve careful control of thermal and deformation conditions to achieve products with required shape specifications and good properties. This article describes TMP methods in producing hot-rolled steel and reviews how improvements in the strength ...

Process Control for Thermomechanical Pulping

IFAC Proceedings Volumes, 1983
Abstract The pulp and Paper industry is snowing increasing interest in a pulping process known as Tnermo-mechanical Pulping - or TMP for snort. In one example of this process wood chips are “refined” to wood pulp directly by mechanical and thermodynamic forces set up between the contra-rotating plates of a so-called TMP Refiner. In the purest form of

Modeling thermomechanical processing of austenite

Journal of Materials Processing Technology, 2003
Abstract This work is divided into two parts. First, a mathematical modeling of the austenite transformation during deformation operations at high temperature is presented. The model introduced by Estrin, Mecking and Bergstrom is employed in predicting the dynamic recovery step while the additional softening by dynamic recrystallization is modeled ...
