Slight amounts of carbon (0:015{0:1mass%) were added into the Fe-30Mn-6Si-5Cr shape memory alloy. The microstructure, precipitation behaviour and shape memory performance of these Fe59Mn30Si6Cr5CX alloys with various thermo-mechanical treatments were investigated. Experimental results show that two particles, the -phase and M23C6 carbide, are observed within the grain-boundary phases. M23C6 car...

An experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Rampur, Nepal during July 2011 to September 2011 with an objectine to determine phenotypic variability of Nepalese finger millet landraces using descriptive statistics, cluster analysis and principal component analysis. FValue of REML procedure of mixed model analysis revealed that highly significant variation wa...

We extend the common theme of random Apollonian packing of circles to consider orientable grains with a noncircular shape. Systems of up to 10(6) grains are examined for a range of polygonal and elliptical shapes using both the random Apollonian packing model and the new rotational random Apollonian packing model which takes into account the extra rotational degree of freedom of noncircular gra...

Based on serial sectioning data, materials microstructure can be reconstructed to digitally represent each grain in three dimensions. This paper attempts to calculate the average shape of the grains through Principal Component Analysis(PCA) , with a theoretical introduction to how this method can be generalized into calculating an average shape of the microstructure. Also investigated is the re...
