times have made it possible to sinter nanometric powders to near theoretical values with little grain growth [13]. The aim of this paper is to investigate the use of spark plasma sintering (SPS) as a rapid and efficient technique to evaluate possible benefits deriving from high energy ball milling of NI 22 Cr 11 Al powders.

After the Great Trek European pastoralists also started settling in the Transvaal. Some of them chose to farm where Johannesburg was to rise later. Each burgher (citizen) was entitled to at least one farm, measuring 1500 morgen or about 3100 acres. The first recorded discovery of gold on the Witwatersrand was made by Jan Gerrit Bantjes in June 1884, on the farm Vogelstruisfontein.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

or solutiontreated material will give best service. The solutiontreated condition is recommended for components that require optimum resistance to creep or rupture. Finegrained (annealed) material may be advantageous at temperatures up to 1500°F with respect to fatigue strength, hardness, and tensile and yield strength.
In metallurgy, a ladle is a vessel used to transport and pour out molten metals. Ladles are often used in foundries and range in size from small hand carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (330 tons). Many nonferrous foundries also use ceramic crucibles for transporting and pouring molten metal and will ...
