As one may see from figure 1 (a) brass consists in cast structure
, with nonhomogeneous disposal of a solid solution and P solid solution and bronze (figure 1 b) has a cast structure
formed from a solid solution, [gamma] 2 solid solution and rounded eutectic of ([alpha]+[[gamma].
Ultrasonic testing and magnetic flaw detection of CESC castings showed dense cast structure
and absence of micro-cracks or any defects.
In the weld area, SeamFree tubing has a recrystallized and reoriented equiaxed grain structure as compared to the cast structure
found in conventional roll formed and welded tubing.
Hot forging refines and densifies the characteristic cast structure
of the starting stock, thereby eliminating inherent cast porosity, redistributing segregation more evenly via metal flow, and reducing the size of as-cast large inclusions.
Topics include microstructure evolution, phase formation and solidification path analysis, grain refinement, micro/macro-segregation, mechanical behavior/properties in the mushy state, solidification cracking/tearing, gas/shrinkage porosity formation, effect of impurities/trace elements, and the impact of cast structure
on the subsequent fabrication and properties of finished products.
Tenders are invited for Construction of Pre Cast Structure
at Various Places at Distt Balaghat
Eutectic alloys--These alloys have between 10% and 13% silicon, and consist mainly of Al-Si eutectic in the cast structure
Heat treatment does not change the typical signs of cast structure
in general but leads to formation of the fine troostitic structure after tempering.
It includes case studies and covers such topics as control of cast structure
and properties, secondary processing and fabrication, simulation and modelling techniques.
This suggests either a difference in the microstructure, the geometry of any pores present or the number of pores in the original cast structure
of the metal in the weld zone.
The final design consisted of a thin-walled aluminum cast structure
, which underwent further processing until the application of the finishing varnish.
The cast structure
is a traditional A356 with a nicely modified eutectic structure.
