Usually, scraps of X22CrMoV12-1 alloy are obtained through machining steam turbine blades and recycled casting. However, this process is considered too costly. The viability recycling with addition vanadium carbide (VC) powder metallurgy was analyzed in study. Scraps VC were milled a planetary ball mill during 10, 30 60 hours. granulometry the determined laser granulometry. evolution particles ...

to study the genetic variations in pistachio cultivars, 42 female pistachio cultivars from station no.2 of rafsanjan, 25 cultivars from pistachio research station of kerman, 40 cultivars from station no. 1 of naseriyyeh region, 3 cultivars from damghan region, as well as 5 ones from khorasan region were taken for experimentation. to carry out cluster analysis based on morphological traits, the ...

To improve the mechanical properties of tires, silica granules can be incorporated into the elastomer as well as carbon black. Ideally, the fragmentation of the granules in the elastomer must be obtained with low mechanical stresses and lead to very small fragments distributed homogeneously in the material. On the other hand, granules must present a sufficient cohesion, in order to avoid the ge...

Grain size analysis is an essential tool for classifying sedimentary environments. The calculation of statistics for many samples can, however, be a laborious process. A computer program called GRADISTAT has been written for the rapid analysis of grain size statistics from any of the standard measuring techniques, such as sieving and laser granulometry. Mean, mode, sorting, skewness and other s...

Introduction: The characteristics of Martian soils are a matter of clear importance when considering the problems that can arise for a rover traversing areas where loose particles are predominant – as Opportunity had the mischance to comprove by itself. The study of Martian surficial materials has been the subject of a number of works, mainly concerned with the texture, constitution, origin and...

Mineral fillers can be defined as “inert materials included in a mix design for some useful purpose”. They can be added to compounds in order to complete a large variety of final properties without increasing costs or to improve specific characteristics like hardness, brittleness, impact strength, compressive strength, softening point, fire resistance, surface texture, electrical conductivity, ...

PURPOSE To carry out a radiological and histomorphometric evaluation of bone response to two xenografts of animal origin, one porcine, and the other bovine, inserted in rabbits' tibiae. MATERIAL AND METHODS Twenty New Zealand rabbits weighing 3900-4500 g were used. Twenty bovine bone grafts (Endobon) in granulated form of 500-1000 μm granulometry were inserted in the proximal metaphyseal area...
