Metallographic analysis of laser soldered chip resistors
33rd International Spring Seminar on Electronics Technology, ISSE 2010, 2010During the last decade laser material processing has been used in more and more fields of electronics technology. Among these techniques laser soldering processes showed great improvements and they offer several advantages mainly in terms of localized heating, rapid rise and fall in temperature, non-contact and easily automated process.

The Metallographer's Role in Damage Analysis
Practical Metallography, 2011Abstract The metallographer's role is of extraordinary importance when clarifying cases of damage. This statement is documented by means of an example of corrosion damage on a brewery pipe. Several different methods have been applied in order to provide for a final result, such as emission spectroscopy analysis ...

Strain analysis in machining using metallographic methods
Metallography, 1987Abstract Strain patterns in 4340 steel chips created during turning at speeds between 36 and 440 m/min (119 and 1442 sfpm) are examined metallographically. A new method, based on the grain elongation orientation in the chip, is developed for quantification of local strains created during plane strain deformation in the primary and secondary ...

Metallographic Analysis of Corrosion Failures
1978The proper analysis of a component failure can provide valuable assistance in determining the validity of a product design. Errors in selection and design as well as materials defects and shortcomings in processing can frequently be revealed. These problems can often be detected in prototype testing or early in production, which results in substantial ...

Metallographic analysis of M2 high speed steel granules
Voprosy Materialovedeniya, 2019The article is devoted to the metallographic analysis of the M2 high-speed steel granules. The study is based on the investigation of the microstructure of the M2 high-speed steel granules obtained by melt atomization. It is demonstrated that granules of similar size can harden both by chemically separating and chemically non-separating mechanism ...

Metallographic Analysis of Parts Produced by Rheocasting Method SEED
Materials Science Forum, 2017The article shows the analysis of castings parts produced by rheocasting method SEED. Structures of as cast and heat treated castings samples were observed by light microscopy and electron microscopy. Scanning electron microscope was also used for studying of fracture surfaces after destruction of the samples during testing of mechanical properties ...
