Optically Active Birefringent Polymer–Lipid Hybrid Microparticles With Dual‐Stimuli Responsiveness

open access: yesAdvanced Optical Materials, EarlyView.
The present study reports on geometrically tunable, magnetic and NIR‐stimuli‐responsive anisotropic microparticles that exhibit intrinsic birefringence due to their lamellar crystalline architecture, enabling label‐free detection under a polarized light.

Analysis of heat affected zone in the micro-electric discharge machining

International Journal of Manufacturing Technology and Management, 2008
It is known from the classical EDM process, which is a thermal process, that a significantly damaged zone, called Heat Affected Zone (HAZ) is generated around the EDmachined features. However, the presence of the analogous zone in the micro-EDM process has not been addressed adequately so far.

Heat Affected Zone Softening Susceptibility Test

Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2020
Abstract There have been a number of unexpected girth weld failures in pipelines, both in-service and during pre-service hydrostatic testing. Investigation of these incidents indicated that the line pipe met industry standard requirements, such as API 5L and the welding procedures had been qualified to API 1104 and construction welding ...

Prediction of residual stresses in the heat affected zone

Journal de Physique IV, 2004
In this paper the behavior of a disc made up of carbon manganese steel and subjected to an axisymmetric heating in its middle zone is considered. The applied thermal cycle generates localized metallurgical solid-solid phase transformations. Contrary to the study performed some years ago, the present work is concerned with relatively thick discs that ...

Heat-Affected Zones in Grinding Steel

CIRP Annals, 1994
Summary Two well known forms of metallurgical damage of ground surfaces involve untempered and overtempered martensite. Both of these forms of metallurgical damage involve martensitic transformations. This paper reviews the nature of such transformations and the special characteristics that pertain in grinding where the time at temperature before ...
