Heat Affected Zone Induced by Laser Forming

Volume 1, 2004
Laser forming induces mechanical and structural modifications around the Laser Scanning Path. Various conventional methods are currently available to estimate properties of materials like X-ray and neutron diffraction, strain/curvature measurement, hole drilling, layer removal, chemical etching, etc.

Heat Affected Zone in the MEMS Wire Bonding

2009 International Conference on Measuring Technology and Mechatronics Automation, 2009
In the wire bonding process of MEMS packaging, Heat Affect Zone (HAZ) is the important factor governing the loop profile of bonding. The height of loop is affected by the length of the HAZ. Factors governing the HAZ are studied. To investigate this relationship, the experiments were done for the various sizes of wire diameter and Free Air Ball (FAB ...

Characteristics of GTA fusion zones and heat affected zones in superalloy 713C

Materials Science-Poland, 2012
In this paper, metallographic examinations, characterising microstructural changes in the 713C superalloy subjected to remelting by GTA method, are presented. In the fusion zone, precipitation of M23C6 or M6C carbides based on chromium and molybdenum was observed.

Dispersoid-free zones in the heat-affected zone of aluminum alloy welds

Metallurgical and Materials Transactions A, 2000
The local microstructure in the heat-affected zone 1 (HAZ1) of a laser beam-welded Al-Mg-Si-Cu aluminum alloy is investigated closely. Dispersoid-free zones (DFZs), where the dispersoids of the base material (BM) are dissolved, are found in the vicinity of the fusion line (FL).

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.

Analysis of LePera’s etching of the heat affected zone of a microalloyed steel

Micron
LePera's etching combined with optical microscopy is an effective way to distinguish various microstructures that can form in microalloyed steels, especially within the heat affected zone (HAZ) of steels that have been welded. Ferritic and bainitic constituents tend to be tinted by the etchant and show up as various shades of tan, while martensite ...
